Title:
Ubuntu 20.04 freeze on Dell inspiron 7373 when screen is turned off
Status in linux package in Ubuntu:
Incomplete
Bug description:
This issue is happening with Ubuntu 18.04 and 20.04 in a Dell Inspiron
7373. 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:

Syslog or systemd journal does not provide any error information about
the crash.
"lsb_release -rd" output:
Description: Ubuntu 20.04 LTS
Release: 20.04
