kernel messages

If I run 'DRI_PRIME=3D1 glxgears', glxgears appears and runs normally for &=
lt; 1
second. However then the screen freezes and pressing Esc to close glxgears =
(and
other keyboard/mouse input) does not work.

Neither the kernel nor Xorg log anything when this happens.

If I run 'DRI_PRIME=3D1 timeout 5 glxgears', after 5 seconds SIGTERM is sen=
t to
the process, it exits and Xorg stops being frozen.

The really weird thing is that if I leave an instance of glxgears (using the
integrated graphics) running at the same time, then glxgears using the disc=
rete
GPU does not cause Xorg to freeze up at all!

This is on a Lenovo P50 with the following setup:

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 0=
6)
01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M200=
0M]
(rev a2)

I'm using debian unstable.
Mesa version: 18.1.6
nouveau version: 1.0.15
Kernel: Linux version 4.17.0-3-amd64 (debian-kernel@lists.debian.org) (gcc
version 7.3.0 (Debian 7.3.0-28)) #1 SMP Debian 4.17.17-1 (2018-08-18)

I've seen this with earlier kernels too.
