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.
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
