After installing these (http://i.imgur.com/pvXL2vc.png) drivers, and rebooting my computer got stuck in a loop at boot up saying - "asking for cache data failed --- assuming data cahe: write through" over and over. I couldn't type anything or open anything just a blank screen repeating the text. I then had to reinstall ubuntu.
The two choices on the top are the same and the two on the bottom are the same. (At least the descriptions are the same). I don't know what caused the problem and since this is my first time with ubuntu idk what I'm doing. How do I prevent this from happening again? I would like to play some games on steam but it prompts me to update the propietary drivers and I'm not sure with one to use to update.
