possibly https://bugs.freedesktop.org/show_bug.cgi?id=22996 based on these references, and the fact that Felix experiences similar behavior, I'm triaging this this bug accordingly. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Triaged ** Changed in: xserver-xorg-video-intel (Ubuntu) Importance: Undecided => Medium ** Summary changed: - [i945] querying information on external monitor with xrandr hangs gpu + [i945] querying information on external monitor with xrandr hangs gpu when compiz is active ** Description changed: Binary package hint: xserver-xorg-video-intel Steps to reproduce: - - attach external monitor (laptop has VGA only) - - run xrandr without parameters (either in commandline or via System->Settings->Display Resolution + - activate desktop effects (i.e., enable compiz) + - attach external monitor (laptop has VGA only) + - run xrandr without parameters (either in commandline or via System->Settings->Display Resolution Symptoms: - - external screen gets a signal and wakes up from sleep - - internal screen turns black (but does not deactivate) - - external screen remains black - - moving the mouse shows the normal gnome cursor - - moving the cursor out of the internal LVDS screen makes it appear on the external screen + - external screen gets a signal and wakes up from sleep + - internal screen turns black (but does not deactivate) + - external screen remains black + - moving the mouse shows the normal gnome cursor + - moving the cursor out of the internal LVDS screen makes it appear on the external screen Output in dmesg: Jan 4 09:22:29 faui44a kernel: [ 549.721418] Skipping EDID probe due to cached edid Jan 4 09:22:29 faui44a kernel: [ 549.756280] Skipping EDID probe due to cached edid Jan 4 09:22:29 faui44a kernel: [ 549.812308] Skipping EDID probe due to cached edid Jan 4 09:22:34 faui44a kernel: [ 554.512359] Skipping EDID probe due to cached edid Jan 4 09:24:05 faui44a kernel: [ 645.971289] Skipping EDID probe due to cached edid Jan 4 09:24:06 faui44a kernel: [ 646.141197] [drm] DAC-6: set mode b Jan 4 09:24:07 faui44a kernel: [ 647.224036] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
