You have been subscribed to a public bug:
After installing Karmic alpha 5 (fresh install, not an upgrade), hitting
alt-tab caused X to freeze up. Screen looks fine (no artifacts) but the
mouse stops responding. I'm able to recover by switching to a virtual
terminal and then restarting gdm. This is on an Dell Inspiron 1525.
I'm guessing this is a compiz-related problem, because turning off
visual effects stops the bug.
I'll attach an xserver log for your pleasure. Let me know what else you
need, I'd love to help.
