Ubuntu Feisty and 3D Desktop Effects

I had to leave my 1st Ubuntu and Linux installation, Breezy Badger, because repositories are no longer available and I cannot install any new software.

The first thing I want to test was the new 3D “Desktop Effects”. I activated both “Windows Wobble when Moved” and “Workspaces on a Cube”. Unfortunately I discovered that I get only one workspace instead of two with default Feisty settings. I set again 2 workspaces in Workspace Switcher “Preferences”.

Big mistake! After this change, I began to loose window’s Titlebars and both top and bottom panels ! No way to close session or use any application other than those already launched. Searching with Google with my Nvidia card, I find a post on Taltab.blog.pkp, Ubuntu 7.04 Feisty Fawn et configuration de l’effet de bureau 3D (Ubuntu 7.04 Feisty Fawn and Desktop Effects settings). The answer would be to add this line in /etc/X11/xorg.conf :

« {Option "AddARGBGLXVisuals" "True"} »

inside Device section, but this line is already there!

After some tweaks, I finally understood:

After activating 3D Desktop Effects, you must NOT use the Workspace Switcher Preferences any more, only Compiz settings.

But this post help me about this : I discovered gnome-compiz-manager and as I don’t want to have to tweak Compiz or being a Geek in order to run it properly, I installed this package.

Quoted from Synaptic :

Gnome compiz manager is small utility, which manage GL Desktop configuration on
XGL/AiGLX. It’s composed of two applications :
- compiz-tray-icon : which launch and stop compiz
- gnome-compiz-preferences : which adjust GL effects
The goal isn’t to propose all compiz options but allow a simple configuration of compiz.

This was enough for my needs. gnome-compiz-manager is easier than gconf-editor to change main settings, as you can see on article’s picture, "Espace de travail (workspace) tab". After that, I did no saw any problem with my Titlebars and panels.

Unfortunately the next time I switched on my computer, the settings I changed within gnome-compiz-manager were lost. I get only one workspace, and the nice applet I ticked Afficher l’icône dans la zone de notification (Show Icon in System tray) was not there.

However I found how to solve this on Ubuntu Geek blog post : Compiz and nVidia on Ubuntu feisty Fawn.

As mocoloco said, System -> Administration -> Restricted Drivers Manager install the correct driver, but also run sudo nvidia-xconfig --add-argb-glx-visuals automatically.

So using the two commands:

or manually adding them with gconf-editor solved the workspace problem. The setting does not vanish ! The only thing missing is the Gnome Compiz Preference icon in the Taskbar :
