I've got a problem with my graphic card. When I try to enable desktop effects on Ubuntu 10.10, "Desktop effects could not be enabled" message appears.

I have Asus ul50vg (nvidia G210M). I don't use any xorg.conf file because when I generate it through nvidia-xconfig, only terminal appears after boot.

Do you have any idea how to solve that problem?

Have you tried installing the official nVidia from their website? – User Feb 20 '11 at 20:01
It causes the same problem. After installation of the driver from nvidia website, Ubuntu drops to terminal during booting. When I remove xorg.conf, it boots normally. Desktop effects, however, can not be enabled anyway. So, the situation is the same as with the Ubuntu nvidia driver. – user11177 Feb 20 '11 at 20:53
When I try to run compiz from terminal, I get: Xlib: extension "GLX" missing on display ":0.0". compiz (core) - Fatal: Root visual is not a GL visual compiz (core) - Error: Failed to manage screen: 0 compiz (core) - Fatal: No manageable screens found on display :0.0 – user11177 Feb 20 '11 at 21:22
It seems to work now. I've changed IDE configuration in bios from Enhanced to Compatible. It's kind of weird because everything used to work with the Enhanced option. However, I think the problem is solved now. I would like to thank Shubh and Stephan for their answers. – user11177 Feb 21 '11 at 22:08
@MichalPavelka Can you pleas answer your own question with what you did to correct this? It's best do to so for future people needing assistance – Marco Ceppi Apr 30 '11 at 12:07

This was fixed by the user by changing IDE mode from Enhanced to Compatible in the system BIOS.

Try to install bumblebee to have both the Intel and Nvidia cards working simultaneously:

sudo apt-get install git
# type password
git clone
cd bumblebee/
sudo ./
optirun glxgears
# check the speed and compare to running:
# If you have google-chrome installed, you can try it with/without optirun and report the FPS values on the mailing list:
optirun google-chrome
