test and question

[Eric Griffin]

Hello All - 

I am just starting on Linux Certification.  I have come to first bump
in the road... hoping someone can help.

When installing Fedora I set the graphics to 256 colors, and
everything was fine.  After using it for several days, I decided to
turn up the graphics to "millions of colors".  When I restarted,
Fedora hangs up during the initial startup sequence.

I guess millions of colors is too much for the hardware at school.

Is there any way to change the display settings at the command line?
as I cannot even get into the GUI now.

THANKS,

EGrif
