I have too experienced X to crash when turning my back to it and it seems to have to do with the screensavers. I tracked it down in the syslog to be related to the i915 DRM bug "fixed" last year by some Ubunto folks (https://bugzilla.ubuntu.com/show_bug.cgi?id=7787) and related to the following error line in syslog:
Sep 7 13:04:24 localhost kernel: [17194357.592000] [drm:i915_wait_irq] *ERROR* i915_wait_irq: EBUSY -- rec: 377606 emitted: 377609 For a full log: http://bildrulle.nu/tech/ubuntu.html This sounds like regression but might not be related to what you are onto. So where do I file if of interest? -- Should not choose GL screensavers when no acceleration is available https://launchpad.net/bugs/49441 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
