Forwarding this issue from a Ubuntu reporter:
https://bugs.edge.launchpad.net/ubuntu/+source/xorg-server/+bug/268853

Problem:
The X screen is garbled during startup before the login dialog is displayed; doing a vt switch clears the corruption and restores proper functionality.

This issue is new to Kubuntu Intrepid Alpha 5, i.e., everything still worked correctly with Alpha 4. I can reproduce it reliably by booting the Live CD (x86_64). While usplash shows up correctly, after X has loaded and while KDE is loading the screen becomes garbled - just the mouse pointer shows correctly (see attached photo).
This can be worked around by switching to any text console and switching back using Ctrl+Alt+F7.
