I have a similar problem, even with last ATI drivers (fglrx) in Dapper.
The difference is I use gdm and gnome rather than kdm and kde.
Near each time I logout from my gnome desktop, the screen becomes either black ou weird with a sort of vertical scrolling and horizontal lines moving everywhere on the screen.
I can generally use Ctrl+ALT+F1 to switch to a console and restart gdm. After that, I can login once again. But sometimes the system really freezes and I cannot switch to a console, not reboot with Ctrl+Alt+Suppr, nor kill Xorg with Ctrl+Alt+Bckspc, nor use the magic sys keys kernel (Alt+PrintScr+s, u and b).
This doesn't happen when reboot or shut off.

My graphic card is a X700 mobility (Acer Aspire 1694WLMI 1024).
