Everything was working perfectly fine on my ubuntu machine since I installed it almost a week ago... until this morning.
My computer has been running slow all day, particularly the dash (and I mean really slow). I went to the system settings with the idea of changing my graphics driver to the proprietary one to see it it would fix the problem. Surprise! Ubuntu doesn't detect my graphic card anymore.enter image description here



I remember there being three options here (at least one proprietary driver and one open source driver). Is there a (safe) way I can force Ubuntu to re-check the hardware without re-installing the whole system?



If it changes anything, the graphics card was from ATI (I don't remember the model, but I could boot my "legacy OS" to check if need be).



Thanks for your help,
- Calixte

Check this thread:
Can't install ATI proprietary drivers in 12.10



From the begging Ubuntu (version 12.10) didn't recognized my graphics card. The solution for me was:



sudo apt-get purge fglrx*

sudo apt-get install fglrx

sudo aticonfig --initial


After reboot my desktop was OK and I did the next check:



sebastian@linux:~$ fglrxinfo

display: :0  screen: 0

OpenGL vendor string: Advanced Micro Devices, Inc.

OpenGL renderer string: AMD Radeon HD 6700 Series  

OpenGL version string: 4.2.11903 Compatibility Profile Context


Now the driver recognizes my graphics cards. On the System Details now I see as Graphics VESA :00. Apparently everything is working fine now.
