I have a Dell C400 laptop that crashes when switching from Text to graphical mode.

Everything is fine on Bootup and I can get into Gnome/KDE fine (I have tried both). I am used the vga=771 option during install.

When I hit shift-alt-control-F1 to open a text terminal, it works fine. When I hit alt-control F7 to return to the graphical environment, the computer locks up (and I have to totally shut down).

Any ideas on how to fix this? I am not sure how to update or change my video drivers if that is what I need to do, please include a link to some step by step instructions.

Thanks.
