Bug Description

Binary package hint: compiz

Since the last update in hardy, compiz has been hard-locking the machine -- I think it's something to do with when I alt-tab between windows, but I'm not entirely sure on that.

The machine doesn't respond to any keypresses, not even Ctrl-Alt-Backspace! But can be ssh'd into from another, and if compiz is killed, it carries on as before.

Confirmed here on an intel i945 too.
I can't really remember what I did to have those crashes but it wasn't only during alt-tabbing (it was often when scrolling a page on firefox IIRC).
I also tried ctrl+alt+backspace without any result, compiz was taking 100% of CPU and killing it + reloading X fixed the issue.
