Public bug reported:
Whenever I run a game that pushes my GPU harder than usual, my monitor
loses signal from the GPU and I have to do a hard reboot (hold down the
power button for a few seconds) of my computer. I'm able to reproduce
the problem consistently by playing Cities Skylines at 4K.
Please let me know if I can be of any assistance in helping to test.
System info:
Ubuntu Version: 18.04.2 LTS
Kernel: 5.1.16-050116-generic
Steps to reproduce:
1) Run Cities Skylines from Steam at 4k
2) Load a new map and start building a city
Expected:
The system should be stable
Actual:
Within 20 - 300 seconds, the monitor loses signal, and I have to perform a hard
reboot.
Notes:
I've attached the last 1000 lines of my syslog after the moment of the crash
until I rebooted.
