Hi
About 1 or 2 time a week the interface crash. Everything freeze except the
mouse, and after some time, I everything close and I get send back to the login
form.
I'm using debian 9 with mate desktop, have a i7-7700k and using its video card.
In the computer I also have an Geforce gt 1030 but I'm using it for pci
passthrough.
Here are the dmesg error:

[303679.069817] [drm] GPU HANG: ecode 9:0:0x85dffffd, in Xorg [986], reason:
Hang on render ring, action: reset
[303679.069820] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[303679.069821] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[303679.069822] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[303679.069823] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[303679.069824] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[303679.069888] drm/i915: Resetting chip after gpu hang

And I'll attach the /sys/class/drm/card0/error error file too.</pre>
