Please help-Video driver mistake

[DevinDow]

While installing XBMC, which was working with my standard Ubuntu install, I accidentally installed NVidia hardware acceleration (sudo apt-get install libvdpau1 nvidia-185-libvdpau) on a notebook with ATI video.
Now XBMC does not work and says it requires OpenGL.
apt-get remove does not work for that package because it's transitional.

Does anybody have suggestions on how I can get my stuff working like it was?

Hi and Welcome !

Have you tried to re-install driver of ATI Card or edit xorg.conf file to you correct driver?

[DevinDow]

I reinstalled every package in the package manager that contained "ATI", to no avail. I appear to not have an xorg.config.

Any other suggestions I can try?
It originally worked with a basic install of Ubuntu.

Now XBMC does not work and says it requires OpenGL.

Could you post exact error message here?

[DevinDow]

Here's the contents of the popup error message:
"Error
XBMC needs hardware accelerated OpenGL rendering.
Install an appropriate graphics driver.

Please consult XBMC Wiki for suported hardware"



Also, I run "glxinfo" from the command prompt, and it says:
"Xlib: extension "GLX" missing on display ":0.0"."

How do I reinstall drivers for my ATI card? They were correctly installed for me automatically when I installed Ubuntu, but I don't want to start over with a clean install of Ubuntu. Is it easy to reinstall Ubuntu and not loose all my packages and settings?

Others may have more elegant solutions, or more precise ones, but if you have really messed up your install, a back up of data and reinstall of OS will get you back up and running.
