When the screen is turned off (so, the suspend or screen lock features are affected), the system freeze and I need to force the laptop turn off and on again. There are some cases when it turn off the screen without issues, but most of the time it freezes. Even "SysRq REISUB" does not work for rebooting when system crash. I can reproduce the issue using `xset dpms force off`. Initially this bug report was filled thinking it was a suspend issue: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1832144 Syslog or systemd journal does not provide any error information about the crash.
