I may have a similar problem in 17.04 (to which I just upgraded). When I try to play a video game, the computer completely freezes anywhere from 30 seconds to 40 minutes after I start. It's done so repeatedly and only when playing this game. I see very little by way of errors in my logs, but I do get errors about the gpu-manager and dkms like those reported here.
Oddly, when I run the following: sudo lshw -c video | grep driver I get: configuration: driver=i915 latency=0 Which is a driver for my intel CPU's graphics processor. This is odd because I have a separate graphics chip, a radeon, installed, and radeon drivers installed but these do not show. When I run: sudo systemctl status gpu-manager.service I get the following, which is similar to what I see in my system log: ● gpu-manager.service - Detect the available GPUs and deal with any system changes Loaded: loaded (/lib/systemd/system/gpu-manager.service; enabled; vendor preset: enabled) Active: inactive (dead) since Sat 2017-07-29 23:01:32 EDT; 25min ago Main PID: 1156 (code=exited, status=0/SUCCESS) Jul 29 23:01:30 ghostwheelLapHP systemd[1]: Starting Detect the available GPUs and deal with any system changes...
