I just installed Mandrake Linux 7.0 and I got all the way through the installation and the when I boot and try to login I can see everything that happens up to the point where it asks for user name to login. Then after about a second, my screen goes blank. My monitor goes into "no input" mode and just stares at me. Any ideas? I can watch the boot up screens and I can even see it ask for a login name, but after a second *poof* it's gone.
