Getting 'Desktop effects could not be enabled' error while trying to enable 'compiz'.

[nayankk]

Hi All,

I am getting following error while trying to enable 'compiz' in 10.4.

"Desktop effects could not be enabled"

Output of http://blogage.de/files/9124/download?compiz-check script present in http://forlong.blogage.de/entries/pages/Compiz-Check is below,

Gathering information about your system...

Distribution: Ubuntu 10.04
Desktop environment: GNOME
Graphics chip: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02)
Driver in use: intel
Rendering method: AIGLX

Checking if it's possible to run Compiz on your system...

Checking for texture_from_pixmap... [ OK ]
Checking for non power of two support... [ OK ]
Checking for composite extension... [ OK ]
Checking for FBConfig... [ OK ]

So, it looks like my hardware support all what it needs for Compiz. What else is going wrong here?

Any help is much appreciated. Sorry, if I provided less details here. Pls let me know if anymore details about the issue is needed.

Thanks in advance.

I'm also getting this message on an Eee 901, was working fine in 9.10 and was working fine for a while after install but now cannot be enabled. My compiz-check output is:

edit: realised other startup apps weren't starting, this PC is on auto-login, logged out to see that it was switched to failsafe login.

Any help?

OK, found the solution.

The problem was with a previous install of nvidia drivers that was removed.
Although I am using the intel driver, the GLX extension from Nvidia was being picked up. This is because the alternatives tool is still linked to nvidia for glx lib.
Fixed it with following commands -

sudo apt-get purge nvidia*
sudo apt-get install --reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg
sudo update-alternatives --remove gl_conf /usr/lib/nvidia-current/ld.so.conf
