Bug#825298: gdm3: After a few minutes the screen goes black

[Bart Vanhaute]

Package: gdm3
Version: 3.20.1-1
Severity: important

When logging in with gdm3, after a few minutes, the screen goes completely
black and locks up. The only operation that is still possible at this point is
pressing the power button to shut down the computer. Using lightdm, I do not
have this problem.

/var/log/syslog contain this relevant section:
