(Version is 1:0.0.16+git20100518+4b8f1a0-1)

When I hotplug or hotunplug my external monitor (DVI on displayport), X frequently, but not always, locks up with a completely corrupted screen.

Now with 1:0.0.16+git20100825+390f1c8-1.

Hotplugging worked before, but hot-unplugging lead to the display being completely garbled, mouse could still move though. VT switching no longer worked, had to reboot to completely remove flickering, even X server restart didn't recover anything.

Here's a video showing the corrupted screen:


Unfortunately, the very quick flickering was hardly caught by the camera.

It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one.
