cli

There are certain files in Ubuntu Linux (or Unix-like systems) that only root user access or edit. How can I edit and/or open files that requires admin (root) access on a Ubuntu Linux?

I’m not able to boot into GUI under Dell desktop system, which uses an ATI HD3750 display card. The display only works with CLI and but when I type startx and get some sort of error or a black screen. How do I fix this issue?
