Cant run AC on Ubuntu 12.04

[debashisp]

There was no problem on the laptop, it runs windows 7 and the windows version of AC worked as it should. But i still want it on my ubuntu.

Here you go :

d@d-platform:~$ glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
299 frames in 5.0 seconds = 59.708 FPS
299 frames in 5.0 seconds = 59.774 FPS
298 frames in 5.0 seconds = 59.575 FPS
296 frames in 5.0 seconds = 59.175 FPS
299 frames in 5.0 seconds = 59.776 FPS
299 frames in 5.0 seconds = 59.774 FPS
298 frames in 5.0 seconds = 59.575 FPS

and a window showing revolving gears!
