X freezes on startup before window manager
I have a computer that cannot get to the window manager setup. It freezes after X starts, but before the KDE config starts. The mouse works, but nothing else.
I am able to Ctrl-Alt-F1 to a commandline sesion. I checked the X log files -- not clues. While in the X session, Ctrl-Alt-Backspace will restart the X session, but it will stall again.
This is a fresh install of Mandrake 10.1 on a Dell Optiplex gx50. This distro has successfully installed on two other same boxes.
I have confirmed the X settings via drakeconf.
I am seeking guidance on what to check next.
Thanks in advance.
