I'm new to linux, but I decided to breathe some new life into my old machine by installing Xubuntu. I was having problems installing from the CD, so I chose to install it in safe graphics mode, figuring it would be easy enough to change it back once everything was installed. Now, however, I seem to be stuck with an insanely low resolution, and I can't find any way to get out of it. How do I get out of safe graphics mode? Or do I have have to install the whole thing again? I know the computer is capable of running in normal mode, as I can get it to work fine by booting directly from the CD, Help.
