Cannot Enable Compiz

[popupblocker]

Hey guys, I recently installed Ubuntu 10.04 by upgrading from 9.10 and now my compiz doesn work for some reason. When I use the command compiz --replace, terminal yields ẗhis:
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

Launching fallback window manager

The thing I don get is that I don even use an Nvidia graphics card. Here is my xconfig:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder75) Fri Mar 12 01:42:27 PST 2010

Are you using the recommended graphics driver? did you try to reinstall Compiz?

Well in 9.10 all my effects worked perfectly, but I've noticed that some Nvidia stuff was installed and that on my xorg.conf, it claims that I'm using an Nvidia driver when in all actuality, I'm using an ATI Mobile Graphics Card O_o I didn't try reinstalling Compiz, but I doubt that would help. Thanks for the quick reply.

Rename the xorg.conf as backup and restart.

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.confbak The system should detect the ATI card and use the open source driver which in many cases will certainly allow compiz. Having an ati card but an xorg which says nvidia will probably have totally confused the system.

I had this kind of problem in Karmic (I hated karmic) Make sure that you have the recommended graphics drivers installed. Go to "Settings>Administrative>Resticted Drivers" Make sure your connected to the internet. Should Work. I would recommend Lucid because One it rocks and two my graphics card worked right away.
