I installed linux (Ubuntu 12.04), with all its drivers. It worked well. But I need your help because last night he showed me "the system operates in degraded graphics mode: screen, graphics card, and input devices may not function properly. You must configure it manually. "It shows me" OK "and once I agree, it shows me" What do you do? ". He then shows me four options:
- Run degraded just for this session graphical mode.
- Configure the graphics settings.
- Fix the error.
- Exit to the console.
So what should I do? Thank you kindly help me because I can not use my computer.
