Re: [gdm-list] GDM Display problems

[Brian Cameron <Brian Cameron Sun COM>]

Mark:

The problem you describe sounds like the monitor isn't getting any input from
the computer.  This is likely a hardware problem (perhaps an unsupported or
broken graphics card).  It sounds like you are not getting any console output
which you need to resolve before worrying about why a GUI program using the
Xserver isn't showing up.  You probably need to work with your distro to
find out what the problem is, or if you have a spare graphics card handy
trying that might fix the problem.
