This morning, I was docked and using a Dell 30" monitor. I reconfigured the X server to stop sending video to the external monitor, suspended the laptop, and after it was suspended undocked it and took it to work. Then I docked it at work, where it was connected to a powered off Dell 24" monitor. Since this time there was a note: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [drm] GPU crash dump saved to /sys/class/drm/card0/error I've filed: https://bugs.freedesktop.org/show_bug.cgi?id=87327 I do want to note that this is only one of many different symptoms and failures that I am seeing. Basically, after suspending and resuming, if I use an external monitor, I have to be prepared to restart the X server --- and sometimes the kernel will sponaneously reboot, sometimes when I do something as simple as accidentally brushing against the power switch on the Dell montor. :-( :-( :-( - Ted _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
