On boot I see these errors:

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.

Possible duplicate of Bug #70354?

Comment 5 Bruno Pagani 2016-10-22 16:25:15 UTC 
Yes, this was probably https://bugzilla.freedesktop.org/show_bug.cgi?id=70354 and should be fixed now.

I don’t know who can change status here but this should be closed.
