Title:
Screen turned off after seconds of inactivity, fixed by xset -dpms;
bug depending on kernel version?
Status in linux-signed-hwe-5.15 package in Ubuntu:
Confirmed
Bug description:
Now and then I have the problem, that the screen turns off after
seconds of keyboard or mouse inactivity. I think that it changes with
kernel versions but I'm not 100% sure that kernel version is the
cause. The annoying bug is present for some time then it's gone, and
after a while, the problem is back.
Two days ago following packages were installed or updated, since then
the problem is there again:

Today I figured out that
xset -dpms
solves the problem but
xset s off
does not.
In gnome-control-center -> Power I have the following settings:
Power Saving: Blank Screen -> 15 minutes ( Selecting Never doesn't
change anything.)
Suspend & Power Button:
Automatic Suspend: On, Delay 15 minutes
Power Button Action: Power off
