Kubuntu 18.04 LTS or 19.04 (issue occurs on both versions)

Freezing should not occur
Kubuntu 18.04 LTS was installed since six months without any issue; issue was first seen on 2019- 08-06 No updates/configuration changes were made before this issue was seen except for disabling Flash plugin in Chromium browser which should have no effect (hopefully) Issue is 100% reproducible since then Issue was both seen on driver version "nvidia-driver-390" and "nvidia-driver-418" Issue is NOT seen when setting PowerMizer to "Prefer Maximum Performance" However, this setting has to be made on every reboot and the laptop fan speed is high (so this is not an acceptable solution) Find attached log files from "sudo nvidia-bug-report.sh"
