Public bug reported:
Xorg server freezes randomly after an upgrade to Natty. I suspect this to be a duplicate of bug #740126. Most symptoms match: * Happens when the screensaver (blank screen) is active * The mouse cursor changes when moving it on different part of the screen, as if applications get events anyway (see comment #53 on bug #740126) It looks like it only happens after a suspend/resume, but I can not confirm this yet. I was able to switch to a console and gather some information, using intel_gpu_dump and apport-bug $(pidof X).
