Switching GTK themes (widgets and icons)

The application lxappearance from XFCE is a useful tool to change icon and widget themes for your favourite window manager.

For me this tool was especially useful to regain icons in my file manager (e.g. thunar) when using a minimal window manager (e.g. awesome). Just run lxappearance and apply a theme, the items should now appear when you start your file manager.

Ubuntu on ASUS EEE PC 1025CE

The ASUS 1025CE EEE PC has a cedarview Atom processor (N2800), 1 GB RAM, and the Intel GMA 3650 graphic chip.

Currently, the graphics chip is not well supported in linux. However it is possible to have a working system including smooth playback of 720p videos.

The following method worked for me:

  1. Install Xubuntu 12.04. I tried 12.10 first, but it didn’t work out for me despite the fact that it includes the newer gma500_gfx driver
  2. Boot your OS and fully update it. You may have to update twice. When update is done, reboot.
  3. sudo add-apt-repository ppa:sarvatt/cedarview
  4. sudo apt-get install add-apt-key
  5. sudo apt-get install cedarview-drm libva-cedarview-vaapi-driver cedarview-graphics-drivers
  6. sudo apt-get install gdm # The default login manager lightdm, didn’t start on my system
  7. sudo dpkg-reconfigure gdm # pick gdm as default
  8. Reboot your system.

On the 1025CE I tested audio, wifi, graphics including video acceleration, and suspend functionality.

Linux is a lot lighter on the RAM (~600MB free) than windows (~100MB free). This results in a smoother experience and more possibilities to run demanding apps.

Citrix receiver in Linux Ubuntu 12.04 or 12.10

When you do the default install of the Citrix receiver 11 in Ubuntu 12.04 or 12.10, it will not run by default. When opening your remote desktop (.ica file) from Firefox, it will fail silently. When trying from command line, you will get an error about loading shared library libXaw.so.7. An easy way to remedy this is to do a
sudo apt-get install ia32-libs

Another problem you may encounter is a missing certificate. We encountered the missing Thawte certificate. Where to get the certificate exactly is up to you (since there are potentially so many different ones) but it must be put in the /keystore/cacerts folder.
