Public bug reported:
[Impact]
* Normal server shutdown will crash when using nvidia in the 319 recommended
optimus setup, or when using usb displaylink output.
[Test Case]
* Start X on an Intel system with a DisplayLink device attached, or nvidia in
optimus configuration.
* xrandr --setprovideroutputsource modesetting NVIDIA-0, or xrandr
--setprovideroutputsource modsetting Intel
*. xrandr --output DVI-0 --off (bug #1185014 workaround)
* xrandr --auto
* Shutdown xserver, no crash should happen.
[Regression Potential]
* Low, the codepath affected only happens on server shutdown, which is already
crashing anyway.
* Considering the code affected, xrandr --setprovideroutputsource and
--setprovideroffloadsink will be the most likely candidates if regressions do
occur.
[Other Info]
* Not upstream yet, but expected there soon.
