demsg from crash.

I am running Arch Linux, and I used to be able to use my discrete graphics card
for games using the method described below, but a while ago that stopped
working, I believe after an update of nouveau and/or the kernel.

I have:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 750M]
(rev a1) with nouveau drivers.

Steps to reproduce:
I run xrandr --setprovideroffloadsink nouveau Intel at the startup of my
desktop (cinnamon). Then I run DRI_PRIME=1 glxinfo (or any other openGL
application that I've tried (glxgears, Civ V)), and X crashes and bring me back
to my display manager (lightdm).

Is there any other info you need, and/or did I report this issue completely
wrong?
