Comment 82 for bug 359392

I have a Thinkpad x61, with an Intel Mobile GM965/GL960 Integrated Graphics Controller, and can confirm this issue, and the work around.

If I have compiz on, I will eventually, and inevitably have a hung system (flashing caps-lock). It is almost always an alt-tab or a ctrl-alt-left/right that triggers this.

At first I thought it was my compiz settings, so I played a little with the various different effects associated with switching applications and switching desktops. All of them seemed to trigger it, but it seemed like the "fancier" (more intensive?) triggered it sooner.

Alas, compiz generally just keeps me from getting work done, so I usually disable it. I have had none of these problems with compiz off.

Please let me know what else I can do to help.
