Full dmesg is attached.
When I try to use discrete gpu with DRI_PRIME=1 (after xrandr
--setprovideroffloadsink), X crashes.
Hardware:
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics Controller (rev 09)
01:00.0 3D controller: NVIDIA Corporation GK107M [GeForce GT 750M] (rev a1)
Acer Aspire V5-573G
If I remember correctly, some time ago everything worked.
