            Bug ID: 89985
           Summary: system video hangs on video switch to fullscreen
           Product: Mesa
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: mbarrera-KK0ffGbhmjU@public.gmane.org

Occasionally, when switching any video playback into full-screen, all system
video, except for the mouse pointer, hangs until reboot. It is possible to SSH
into the machine for a while until it freezes completely.

Video card: NVIDIA Corporation GK104M [GeForce GTX 670MX] (rev a1)
Operating system: Archlinux with linux 3.19.3-3-ARCH

nouveau-fw is installed and nouveau.config=NvGrUseFW=1 is in the kernel
parameters.

I logged in via SSH into the blocked machine and dumped dmesg's output, it
produced a 6MiB sized file of only:

You shouldn't need to use blob context switching firmware... I'd start by
removing

nouveau.config=NvGrUseFW=1

Also, if this is recent, and you're using libdrm-2.4.60, try downgrading to
libdrm-2.4.59.

Effectively this is recent, I downgraded to libdrm-2.4.59 and removed the
kernel parameter. I still could reproduce the issue with a secondary screen and
with the primary only, It tried that because I though it could be because of
the secondary display.

relevant output of dmesg when reproducing with two displays:

[  195.394185] compiz[1209]: segfault at 7f23ad5c7580 ip 00007f23ad5c7580 sp

relevant output of dmesg when reproducing with a single display:
