My brightness function keys always worked, but suddenly they stopped working as well as the “Reduce backlight brightness” option in Power Management Preferences

Every time I unplugged my power cord the monitor dimmed automatically. Now not even with the function keys I get my brightness down.

This happened in my HP Pavilion dv5-1020ep running Ubuntu 8.10 64 bits.

Here some additional info after searching in the Ubuntu forums and Google:

grep . -r /var/lib/acpi-support/*-*

/var/lib/acpi-support/bios-version:F.20
/var/lib/acpi-support/system-manufacturer:Hewlett-Packard
/var/lib/acpi-support/system-product-name:HP Pavilion dv5 Notebook PC
/var/lib/acpi-support/system-version:Rev 1

more /proc/acpi/video/DVGA/LCD/brightness

not supported

sudo echo -n 5 > /proc/acpi/video/DVGA/LCD/brightness

bash: /proc/acpi/video/DVGA/LCD/brightness: Permission denied

This happened either after a kernel or hal update…

I found a workaround, that allow the brightness to be changed. This isn’t the fix, if I unplug the power cord the brightness keeps it’s value. Still, the function keys do their job…

Just add acpi_osi=”Linux” to your grub menu:

sudo vi /boot/grub/menu.lst

title           Ubuntu 8.10, kernel 2.6.27-11-generic
root            (hd0,2)
kernel          /boot/vmlinuz-2.6.27-11-generic root=UUID=cba317f7-1d97-4cf8-9ac8-a4a6aaf0ea81 ro quiet splash acpi_osi="Linux"
initrd          /boot/initrd.img-2.6.27-11-generic
quiet

Update 1: There is a bug report about this problem.

Update 2 (16/01): Recent acpi and kernel updates just solved the problem

UPDATE Dec10: New post updated from here.

One of my “to achieve” points was syncing my calendar and contact information from my Windows Mobile 5.0 Smartphone (Qtek 9100).

This post is an update from my previous one, after my Ubuntu 8.10 upgrade. Please refer to that first post if you’re using previous versions of Ubuntu. I upgraded Ubuntu and Synce, so if you are installing it from scratch and you’re having problems please let me know. I’ll try and help you.

I will show how I’m syncing my phone with Evolution using Synce in Ubuntu 8.10.
This is based in Synce wiki and Synce mailing lists.

Note: save this post if you’re using Gnome Network Manager, because you may stay without Internet after installing the core libraries. It’s very easy to fix though. In Ubuntu 8.10 I don’t have this problem.

Disclaimer

This is not an official Synce guide. This is my personal eXPerience using a single device, with a single WM flavor and a single OS.

If you are starting to play around with Synce, this post could help you if you’re using the same WM and Linux OS’s, but you should always check Synce official wiki for updates.

If you are having problems, the Synce mailing lists are probably the best place to go right now. The people are friendly and will help you solving your problems. You could also send me an email. If I can, I’ll help, if not, I’ll guide you in the right direction.

My setup

This is my current environment:

• Qtek 9100 device running Windows Mobile 5.0 (WM5)
• Ubuntu 8.10
• Evolution as my Personal Information Manager

Adding repositories

• Go to System > Administration > Software Sources
• Add the following Third Party software

deb http://ppa.launchpad.net/synce/ubuntu intrepid main

• Close and Reload, as asked, your sources

Core libraries

• Get the core libraries

sudo apt-get install synce-hal librra0-tools librapi2-tools

• Connect your device and run

synce-pls

You should see a list of files on your device. If so you have a working connection to your device!

Password protected device

When running synce-pls, if you have the following error, your device is password protected. If so, install SynCE-GNOME or SynCE-KPM to provide a password prompt on device connect.

I didn’t try this because my device isn’t password protected…

WARNING **: synce_info_from_odccm: Failed to get a connection for :
Not authenticated, you need to call !ProvidePassword with the
correct password. pls: Could not find configuration at path
'(Default)'

Gnome Network Manager

If you’re running Gnome Network Manager you don’t have Internet by now because your phone is now the new default network connection.

Follow this and you should be fine:

• Check what ethernet device was given to your phone (in my case is rndis0)

ifconfig -a | grep 80:00:60:0f:e8:00  | cut -d " " -f 1

• Add the next line to /etc/network/interfaces (replace rndis0 with the result from the previous command)

sudo vi /etc/network/interfaces

add iface rndis0 inet dhcp to the file

• This will make Gnome Network Manager ignore the interface

• Restart your network

sudo /etc/init.d/networking restart

No devices are connected to odccm

If you get an error that no devices are connected to odccm you should probably blacklist ipaq module:

• Add the next line to /etc/modprobe.d/blacklist

sudo vi /etc/modprobe.d/blacklist

add blacklist ipaq to the file

• After that you can remove any currently active ipaq modules

sudo rmmod ipaq

Syncing with OpenSync (needed packages)

In order to sync your device you need to use OpenSync.

sudo apt-get install multisync-tools opensync-plugin-evolution opensync-plugin-synce

Sync-engine

Sync-engine must be running in order to sync your phone. In Ubuntu the Engine should start automatically when you connect your device.

• Download the config.xml file needed by sync-engine

cd ~/.synce/
wget

http://synce.svn.sf.net/svnroot/synce/trunk/sync-engine/config/config.xml

Now the tip. The current config.xml has the AutoSyncCommand and the Disable commented. Uncommented, leaving it disabled.

• You can download my own

cd ~/.synce/
wget http://lofspot.net/synce/config.xml

• Start sync-engine if needed

synce-sync-engine

Connect your phone via usb. You shouldn’t get any errors.

Create a partnership

You have to create a partnership between device and computer using one of two methods:

1. Via command line
2. Using synce-kpm (graphical and recommend)

(1) You can then use the command

synce-create-partnership "Linux desktop" "Contacts,Calendar"

The “Linux desktop” string can be any string of 20 characters or less. The available items for synchronization are:

* Contacts
* Calendar
* Tasks
* Files

When specifying items to sync, they must be separated by commas. You must also surround the list in double quotes and the string must not contain any whitespace.

(2) Or install synce-kpm

sudo apt-get install synce-kpm

Now run synce-kpm

synce-kpm

Go to Partnership manager. You probably have already partnerships created if you ever synced your phone under Windows.

I chose to start by deleting my existing partnerships and start from scratch, but, as pointed out by Guido Diepen if your device runs WM6 this will erase all your contacts/tasks/calendar. So do not delete your partnership if you’re running WM6 and your want to keep your data in the device.

In my case, having WM5, I’ve deleted every partnerships and created a new one. I chose to sync Calendar, Contacts and Tasks.

synce-opensync-plugin

Check the list of the available plugins:

msynctool --listplugins

You should have synce-opensync-plugin.

If you don’t see the above plugin in the output of msynctool, then download the plugin and copy this file to /usr/lib/opensync/python-plugins.

I already had the plugin.

Create OpenSync group

A group between SynCE and your chosen PIM application must be initiated.

I’m using Evolution (evo2-sync).

msynctool --addgroup synce-sync
msynctool --addmember synce-sync synce-opensync-plugin
msynctool --addmember synce-sync evo2-sync

Syncing your device (finally)

• Start sync-engine if needed and connect your device

synce-sync-engine

• Start synce-kpm

synce-kpm

• Sync with OpenSync

msynctool --sync synce-sync

This could take some time the first time, so be patient. You can check your progress in synce-kpm.

After the msynctool command ends completely, check Evolution

Important: keep your device on, so the synchronization isn’t interrupted.

In Ubuntu 8.10 I only need to call the msynctool after connecting the device and be sure the firewall isn’t causing trouble. Very easy.

Firewall

If you have a firewall active, and you’re having troubles syncing your device try to disable it.

Inconsistencies while syncing

While syncing kepp an eye out in you console. I had some inconsistencies in my data (contacts) than I had to resolve by selecting witch version of a contact I would like to keep.

Please, feel free to post a comment or email me at lof-ubuntu-xp [(at)] lofspot.net.

This is just a “this is how I did it” post. I probably won’t be able to help you, especially in another distribution/version or phone, still feel free to share your experience.

Last week Ubuntu 8.10, aka The Intrepid Ibex, was released.

Time to updgrade First in my laptop.

I will be the using the 64 bit alternate cd to upgrade. This means that the upgrade will have a cd image as his source, and not the Internet. This way it’s much faster.

Before you start

• Check for updates using Update Manager
• Backup your data
• Check the Release Notes
• Download Ubuntu (I recommend using Torrents)
• Check the file hash (example: md5sum ubuntu-8.10-alternate-amd64.iso)
• Be sure to upgrade from Ubuntu 8.04.
• Use Gmount-iso to mount the iso file. This way cd could be mounted without having to burn a cd.

In the Terminal, go to the cd mount point (example: /media/cdrom) and type:

gksu "sh /cdrom/cdromupgrade"

And now we wait…

During the updgrade there may be some questions about replacing some configuration files. I replaced them all with the new versions.

After restarting and reactivating my Software Sources there were more updates to do. This is because Ubuntu deactivates other software sources and because I made the upgrade from the alternate cd.

Issues

• Non-Issue 1: It really seams faster
• Non-Issue 2: Install OpenOffice 3.0
• Issue 1: I was missing some software I wanted to get back.
  • gVim
  • gnuCash
  • Mail Notification
  • LAMP Server (check the link for details)
• Issue 2: Reactivate Software Sources (System > Administration > Software Sources) updating them to Intrepid.
• Issue 3: Add to re-install EnvyNG-Qt (sudo apt-get install envyng-qt) and enable the ATI driver.
• Issue 4: Scrolling in Firefox was extremely slow. I reinstalled the ATI driver and it’s fixed now.

sudo apt-get remove --purge fglrx*
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati
sudo dpkg-reconfigure -phigh xserver-xorgsudo dpkg-reconfigure -phigh xserver-xorg

My old laptop’s battery is dying, and used that as an excuse to buy myself a new on

I had a HP Pavilion zt3240EA, and have been very happy with it. Nice machine. Still, age weights on every one.

I’m gonna be installing Ubuntu 8.04.1 LTS Desktop Edition, 64 bits version, on my new HP Pavilion dv5-1020ep.

Download and Burn a CD

• Go to Ubuntu Download Page and download Ubuntu.
• Check the downloaded file hash. The output must be the same as you see in the Ubuntu Hashes Page.

md5sum ubuntu-8.04.1-desktop-amd64.iso

• Burn a cd (you can use Brasero, for example, if you already use Ubuntu).

Running the live cd

• Boot from the cd.
• After booting it’s important to check the integrity of the cd. Burning cds also fails.

Hardware to check (during the live cd session)

• Graphics (only 1024×768, but check)
• Sound (check)
• Media buttons (check)
• Cable network (check)
• Wireless network (the proprietary Atheros wireless card was found, not tested)
• HP media command (not working)
• Integrated Webcam (check)

Hard Drive Partition Layout

/dev/sda
	/dev/sda1	ntfs	Vista			36002 MB
	/dev/sda2	ntfs	Vista Recover		 8450 MB
	/dev/sda3	ext3	/			10240 MB
	/dev/sda5	ext3	/home 			10240 MB
	/dev/sda6	ext3	/storage		94072 MB
	/dev/sda7	swap				 1028 MB

Post-install: Graphics Card

I installed EnvyNG using the Synaptic Package Manager (look for envyng-gtk) and just had to run it (Applications > System Tools > EnvyNG), after closing Synaptic (important), and choose to “Install the ATI driver (Automatic Hardware Detection)” option.

I now have a normal 1280×800 screen resolution and some desktop effects are already active.

There is an ATI Catalyst Control Center under Applications > Other, where you can tweak things up.

Problems to Solve: if I have Compiz on, there’s a terrible flickering when playing back movies.

Post-install: CPU Frequency Scaling

After installing Ubuntu I noticed that the frequency of both cores was always at 2 GHz (the cpu max frequency in my case).

Because this is a laptop I want the cpu to scale that frequencies as needed.

Useful tools:

sudo apt-get install cpufrequtils

You can check this behavior by:

• Adding the “CPU Frequency Scaling Monitor” to your Gnome Panel (add two, one for each core). Frequency should change while you work.
• Check the output of the following (here you can check the driver used – powernow-k8 – and the current scaling policy)

cpufreq-info

Reference: How to use CPU frequency scaling (cpufreq)

After some time of research here’s a very simple method (read the Reference for much more details):

• Add the following to your /etc/rc.local file ( sudo vi /etc/rc.local )

modprobe powernow-k8
sudo cpufreq-selector -g userspace
/etc/init.d/powernowd restart

exit 0

• Add the -n option to your /etc/default/powernowd file ( sudo vi /etc/default/powernowd )

OPTIONS="-q -n"

• Restart

Useful tips:

• Check available frequencies for your cpu (if you have more than one core also check cpu1, cpu2, etc.)

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

• Check current governor

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

• Check available governors

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

Problems to solve: restarting powernowd always change the governor to ondemand.

Post-install: Wireless Network card

A warning in the Notification Area showed that a Proprietary Driver is enabled (Atheros wireless card).

lspci | grep Atheros to check the driver name.

Followed this instructions from Ubuntu Forums, now I can use the wireless card, I found several networks, the signal is good, I connect with my password, but I can’t get an IP… This means no Internet.

Problems to solve: connect to the Internet with sucess.

Post-install: Laptop Optimizations

Here’s some useful tips if you’re running on a laptop:

• Change the ENABLE_LAPTOP_MODE option to true ( sudo vi /etc/default/acpi-support )

ENABLE_LAPTOP_MODE=true

• Install and run powertop. Follow the instructions on-screen (more info here).

sudo apt-get install powertop

sudo powertop

Post-install: Sound Card

Sound works fine, but the Master mute button doen’t mute the Front. This means that the columns still output sound.

To fix this go to System > Preferences > Sound and select the Front device in the list below.

Post-install: File System

Besides the / and /home partitions, only root have permissions to write in every other partitions. In my case /storage.

So, we have to add permissions to our user:

sudo chown -R youruser:youruser /storage
sudo chmod -R 755 /storage

Post-install: Updates

Update Manager warned me about 120 available updates. Just letting it go…

Post-install: Multimedia

Virtualbox 2.0 is out and now it’s easier to install and maintain.

Install

• Download and register Sun authentication key

wget -q http://download.virtualbox.org/virtualbox/debian/sun_vbox.asc -O- | \
sudo apt-key add -

• Go to System > Administration > Software Sources and Third-Party Software.

• Add the following sources for Hardy (check your distibution here):

deb http://download.virtualbox.org/virtualbox/debian hardy non-free

• Now you can go to Synaptic Package Manager and look for virtualbox. This way you can uninstall previous Virtualbox installations (Synaptic Package Manager will do that for you).

• Don’t forget to install the new Guest Additions if you’re using a Windows Virtual Machine.
• Now you’ll receive updated through Update Manager.

______________________________________________________________________________________

UPDATE AUG 10: Virtualbox 1.6.4 is out. Added a new “Update Virtualbox to a new version” section.

I have Virtualbox OSE (Open Source Edition) installed. I use it basically to use Office, when needed.

Currently I only restart to Windows to sync my iPod Touch, and that’s because Virtualbox OSE doesn’t support USB.

But there’s a version, provided by Sun, that supports USB devices.

Uninstall Virtualbox OSE

If you already have Virtualbox installed go to Applications > Add/Remove… and look for virtualbox to uninstall your current version.

I also went to System > Administration > Synaptic Package Manager and also looked for virtualbox to remove every trace of it.

Install Sun Virtualbox (currently v1.6.2 v1.6.4)

Go to Virtualbox download site and go to Binaries (all platforms).
Select your Platform (Ubuntu 8.04 x86 in my case), agree to the license and continue to the download.

After the download is complete start the installer (or double click the .deb file):

sudo dpkg -i virtualbox_1.6.2-31466_Ubuntu_hardy_i386.deb

And it’s that easy.

Virtualbox Users

• Go to System > Administration > Users and Groups

• Unlock the Settings and go to Manage Groups

• Find the vboxusers group and click Properties

• Select your username in the Group Members list

USB Support

By default the usb support is disabled. To enable it do the following:

sudo gedit /etc/init.d/mountdevsubfs.sh

Now look for:

#
# Magic to make /proc/bus/usb work
#
#mkdir -p /dev/bus/usb/.usbfs
#domount usbfs “” /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
#ln -s .usbfs/devices /dev/bus/usb/devices
#mount --rbind /dev/bus/usb /proc/bus/usb

And replace with (remove # from the last 4 lines):

#
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs
domount usbfs “” /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb

Restart your machine.

Update Virtualbox to a new version

When a new version is available you just need to download it and double click the .deb file. It’s that easy.

Last tips

Sun Virtualbox is now available at Applications > System Tools > Sun xVM VirtualBox.

In my case, at the end of the installation, Virtualbox found my previous virtual machine (Windows XP) and upgraded it to the new version, allowing me to use that virtual machine.

Because of this, every configuration was set and I only had to activate the USB support in my virtual machine.

Check my Virtualbox OSE post and see how to:

• Create a new Virtual Machine

• Share folders with the Virtual Machine (install Guest Additions for Windows)

• VirtualBox running modes

Note: if you had Guest Additions for Windows in your old virtual machine, uninstall it and install the new 1.6.2 version.

UPDATE Aug20: Added a “Synce 0.12 Update” section.
UPDATE Jul30: Synce 0.12 is out. It was updated by Update Manager in my machine and all worked fine synce-kpm had some images broken before, but this update fixed that.
UPDATE Jul15: Kernel 2.6.24-19 in Ubuntu notes (check “Kernel module”), new “Firewall” and “Inconsistencies while syncing” sections, “Day to day config” script additions.
UPDATE Jun28: Added a “Disclaimer” section (please regard that) and a “My setup” section, some extra information in the “Kernel module” section and an important information about WM6 in the “Create a partnership” section.
UPDATE Jun05: What to do when you update your kernel (check “Kernel module” bellow).
UPDATE Jun04: Sync-engine and create partnership commands changed (Hardy users after system update).

One of my “to achieve” points was syncing my calendar and contact information from my Windows Mobile 5.0 Smartphone (Qtek 9100).

After trying for some time, I used a tip from Synce mailing lists. This tip was great for me because the author was also having troubles and started from scratch.

I think my problem was the config.xml file. I believe that if I just followed the instructions from the good folks from Synce, as I first did, but changed the config.xml, as in the mailing list, I wouldn’t have needed to clean my system.

So, if you are starting, you probably could skip the “clean your system” part.

I will show how I’m syncing my phone with Evolution using Synce in Ubuntu 8.04.
This is based in Synce wiki and Synce mailing lists.

Note: save this post if you’re using Gnome Network Manager, because you’ll probably stay without Internet after installing the core libraries. It’s very easy to fix though.

Disclaimer

This is not an official Synce guide. This is my personal eXPerience using a single device, with a single WM flavor and a single OS.

If you are starting to play around with Synce, this post could help you if you’re using the same WM and Linux OS’s, but you should always check Synce official wiki for updates.

If you are having problems, the Synce mailing lists are probably the best place to go right now. The people are friendly and will help you solving your problems. You could also send me an email. If I can, I’ll help, if not, I’ll guide you in the right direction.

My setup

This is my current environment:

• Qtek 9100 device running Windows Mobile 5.0 (WM5)
• Ubuntu 8.04
• Evolution as my Personal Information Manager

Adding repositories

• Go to System > Administration > Software Sources
• Add the following Third Party software

deb http://ppa.launchpad.net/synce/ubuntu hardy main

• Close and Reload, as asked, your sources

Kernel module (for Kernel < 2.6.24-19)

If you’re using Kernel 2.6.24-19 or newer you should skip this part.

• Unload the current modules:

sudo rmmod rndis_host cdc_ether usbnet

• Now we have to delete the old drivers, such that the kernel will not reload them next time:

sudo rm /lib/modules/`uname -r`/kernel/drivers/net/usb/{rndis_host,cdc_ether,usbnet}.ko

• Now we have to get and compile the new drivers:

sudo apt-get install usb-rndis-source cdbs
sudo module-assistant auto-install usb-rndis

Every time you update your system kernel redo this steps. Everything should be fine again

My eXPerience with Kernel 2.6.24-19 in Ubuntu 8.04 Hardy Heron:
Although Synce official wiki recommends skipping this step for kernel 2.6.24-19 and newer, I had to redo this steps through all 2.6.24-19 kernel updates Hardy as been getting out. If you’re using this kernel try first skipping this step and if you have no joy redo them.
I realize something is wrong if my Internet connection is lost when I connect my device. ifconfig returns eth1 instead of rndis0 (see the “Gnome Network Manager” bellow).

Core libraries

• Get the core libraries

sudo apt-get install odccm librra0-tools librapi2-tools

• Connect your device and run

synce-pls

You should see a list of files on your device. If so you have a working connection to your device!

Password protected device

When running synce-pls, if you have the following error, your device is password protected. If so, install SynCE-GNOME or SynCE-KPM to provide a password prompt on device connect.

I didn’t try this because my device isn’t password protected…

WARNING **: synce_info_from_odccm: Failed to get a connection for :
Not authenticated, you need to call !ProvidePassword with the
correct password. pls: Could not find configuration at path
'(Default)'

Gnome Network Manager

If you’re running Gnome Network Manager you don’t have Internet by now because your phone is now the new default network connection.

Follow this and you should be fine:

• Check what ethernet device was given to your phone (in my case is rndis0)

ifconfig -a | grep 80:00:60:0f:e8:00  | cut -d " " -f 1

• Add the next line to /etc/network/interfaces (replace rndis0 with the result from the previous command)

sudo vi /etc/network/interfaces

add iface rndis0 inet dhcp to the file

• This will make Gnome Network Manager ignore the interface

• Restart your network

sudo /etc/init.d/networking restart

No devices are connected to odccm

If you get an error that no devices are connected to odccm you should probably blacklist ipaq module:

• Add the next line to /etc/modprobe.d/blacklist

sudo vi /etc/modprobe.d/blacklist

add blacklist ipaq to the file

• After that you can remove any currently active ipaq modules

sudo rmmod ipaq

Clean your system

If you have been playing around with Synce without success you may want to clean your system before continuing.
Check this tip for more info.

• Check what packages to remove from the result of each of the following

dpkg-query -l *sync*
dpkg-query -l *dccm*
dpkg-query -l *rra*
dpkg-query -l *rapi*
dpkg-query -l *multis*
dpkg-query -l *opensync*

• I then did

sudo apt-get remove libsynce0 multisync-tools opensync-module-python \
 opensync-plugin-evolution opensync-plugin-synce python-opensync synce-kpm \
 synce-sync-engine
sudo apt-get remove odccm
sudo apt-get remove librra0 librra0-tools
sudo apt-get remove librapi2 librapi2-tools
sudo apt-get remove multisync-tools
sudo apt-get remove libopensync0

• Remove your Synce home config folder

rm -rf ~/.synce

• Removed the byte compiled file

sudo rm -f /usr/lib/opensync/python-plugins/synce-opensync-plugin-2x.pyc

Syncing with OpenSync (needed packages)

In order to sync your device you need to use OpenSync.

sudo apt-get install odccm librra0-tools librapi2-tools multisync-tools \
 opensync-plugin-kdepim opensync-plugin-synce
sudo apt-get install multisync-tools opensync-plugin-evolution opensync-plugin-synce

Sync-engine

Sync-engine must be running in order to sync your phone.

• Download the config.xml file needed by sync-engine

cd ~/.synce/
wget

http://synce.svn.sf.net/svnroot/synce/trunk/sync-engine/config/config.xml

Now the tip. The current config.xml has the AutoSyncCommand and the Disable commented. Uncommented, leaving it disabled.

• You can download my own

cd ~/.synce/
wget http://lofspot.net/synce/config.xml

• Start sync-engine

sync-engine synce-sync-engine

Connect your phone via usb. You shouldn’t get any errors.

Create a partnership

You have to create a partnership between device and computer using one of two methods:

1. Via command line
2. Using synce-kpm (graphical and recommend)

(1) You can then use the command

create_partnership.py synce-create-partnership "Linux desktop" "Contacts,Calendar"

The “Linux desktop” string can be any string of 20 characters or less. The available items for synchronization are:

* Contacts
* Calendar
* Tasks
* Files

When specifying items to sync, they must be separated by commas. You must also surround the list in double quotes and the string must not contain any whitespace.

(2) Or install synce-kpm

sudo apt-get install synce-kpm

Now run synce-kpm

synce-kpm

Go to Partnership manager. You probably have already partnerships created if you ever synced your phone under Windows.

My advice, after playing around is to delete every partnerships you already have and create a new one.

I chose to start by deleting my existing partnerships and start from scratch, but, as pointed out by Guido Diepen if your device runs WM6 this will erase all your contacts/tasks/calendar. So do not delete your partnership if you’re running WM6 and your want to keep your data in the device.

In my case, having WM5, I’ve deleted every partnerships and created a new one. I chose to sync Calendar, Contacts and Tasks.

synce-opensync-plugin

Check the list of the available plugins:

msynctool --listplugins

You should have synce-opensync-plugin.

If you don’t see the above plugin in the output of msynctool, then download the plugin and copy this file to /usr/lib/opensync/python-plugins.

I already had the plugin.

Create OpenSync group

A group between SynCE and your chosen PIM application must be initiated.

I’m using Evolution (evo2-sync).

msynctool --addgroup synce-sync
msynctool --addmember synce-sync synce-opensync-plugin
msynctool --addmember synce-sync evo2-sync

Syncing your device (finally)

• Start sync-engine and connect your device

sync-engine synce-sync-engine

• Start synce-kpm

synce-kpm

• Sync with OpenSync

msynctool --sync synce-sync

This could take some time the first time, so be patient. You can check your progress in synce-kpm.

After the msynctool command ends completely, check Evolution

Important: keep your device on, so the synchronization isn’t interrupted.

Firewall

If you have a firewall active, and you’re having troubles syncing your device try to disable it.

Inconsistencies while syncing

While syncing kepp an eye out in you console. I had some inconsistencies in my data (contacts) than I had to resolve by selecting witch version of a contact I would like to keep.

If I have another one I’ll post an example.

Day to day config

To simplify I created a script to synchronize my phone.

touch sync_smartphone.sh
chmod a+x sync_smartphone.sh
vi sync_smartphone.sh

Add to the file (remove the Strikethrough text):

#!/bin/bash

echo ""
echo ""
echo "---> disconnect your device"
echo ""
sleep 10

sudo ufw disable

echo ""
echo "---> connect your device"
echo ""
sleep 10

sync-engine synce-sync-engine > engine.log &
sleep 20
synce-kpm > kpm.log &
sleep 20
msynctool --sync synce-sync > synctool.log

sleep 10
sudo ufw enable

Now connect your phone, run sync_smartphone.sh and check your progress in synce-kpm graphical UI.

update: I had to my script disable/enable ufw firewall commands and logging to synce engine, synce-kpm and mysynctool.

Please, feel free to post a comment or email me at lof-ubuntu-xp [(at)] lofspot.net.

This is just a “this is how I did it” post. I probably won’t be able to help you, especially in another distribution/version or phone, still feel free to share your experience.

Synce 0.12 Update

If you updated Synce to version 0.12 using Update Manager, you may me incapable of select the package synce-sync-engine for update.

Although this package wasn’t updated, my config worked fine and without any change.

This version of Synce replaced the odccm daemon with synce-hal, and, basically, this is the problem. Update Manager doesn’t seem to know what to do.

So, go to System > Administration > Synaptic Package Manager, look for synce-sync-engine, right click the package and select “Mark for Upgrade”. This will uninstall the odccm package and install synce-hal.

___________________________________________________________________________________________________

A friend of mine asked me about a Linux equivalent to Launchy, a keystroke launcher for Windows.

And that is GnomeDo.

Install

• If you have an older version of GnomeDo start by removing it and deleting is plugins:

sudo aptitude purge gnome-do gnome-do-plugins \
gnome-do-plugin-rhythmbox

rm -rf ~/.local/share/gnome-do/plugins/

• Then add the following software sources (System > Administration > Software Sources):

deb http://ppa.launchpad.net/do-core/ubuntu hardy main
deb-src http://ppa.launchpad.net/do-core/ubuntu hardy main

• Install GnomeDo (currently v0.5.97):

sudo aptitude update && sudo aptitude install gnome-do

Using GnomeDo

Go to Application > Accessories > GNOME Do to start the application (it will also appear in your notification area).

To summon GnomeDo press Super+Space (the Super key is the one with the windows logo).

Know just type what you want to launch. If you want to open a Terminal window start typing Termi and your good to go.

Use the Down key to view all the options available to what you’re writing and he Tab key to navigate horizontally (you’ll get it).

Tips

• In Preferences > General select the 3 options related to the First-Launch Behavior

• Choose your favorite appearance in Preferences > General (I chose Mini)

• Check Always show results windows (you’ll see what you’re writing) (I’m having trouble when restarting so I turned it off)

• If you don’t like the Super + Space combo choose another one in Preferences > Keyboard

• Take some time going to Preferences > Plugins (some of them have options to Configure)

• Restart GnomeDo when you choose new Plugins

• Use the About button to discover how to use a plugin in Preferences > Plugins

My favorite Official Plugins

Evolution: I just need to type a contact name to easily send an email
Files and Folders: write for example a new folder name, click down until you bypass the available matches, click Tab, click Down and look for Create Directory (it goes to the Desktop); also add your favorite folders in order to quickly access them

As you install, uninstall and update applications there are some garbage left behind.

Autoremove

When you run autoremove, packages that have been installed but are no longer in use, are removed.

sudo apt-get autoremove

Autoclean

Autoclean removes .deb files from packages no longer installed on your system.

sudo apt-get autoclean

Do you have other cleaning tips? Send me an email or post a comment.
