I've encountered a quite serious problem with my Ubuntu 14.04 LTS. My display driver is defect and I really need this one file on the desktop. The display will turn black whenever I start Ubuntu.
Is there a way to: 1. Restore to the stock display driver? 2. Reinstall Ubuntu keeping my files? or 3. Get that one file with Windows 7 (yes, I'm dual booting) or the Ubuntu live CD?
Thanks for all answers.
