Re: Monitor Problem???

My main computer runs Debian Buster and is displaying some unusual

The monitor is blanking, without warning, at random times, and restoring
the screen while I working. There is no warning, nor does the computer
seem to be overheating (I continuously monitor the temperature).
I rather suspect that it may be a hardware problem. I keep the software
up to date.
I am querying this group because I can't think of a more knowledgeable
source. Any thoughts and suggestions of things that I might be able to
test will be very welcome.
I suspect it is a software problem, not a hardware problem. The reason
is I have been seeing the same for almost a year now with my display. I
can't find anything that indicates a hardware problem and after all this
time the display/monitor is still trucking on without the problem
getting any worse.
I am not 100% sure, but it seems like sometimes the display is put into
sleep mode and can't be woken up. Restarting X or doing a modprobe from
a remote machine over ssh doesn't help. Nor does anything else. The only
way to get the monitor to activate again is to reboot. After some
digging I gave up on finding the root cause and accepted that I'd have
to reboot once in a while. There is nothing in the logs to give any
indication of a possible cause. Maybe I should have tried harder, but I
just don't have the time for that at the moment.
FYI, this is the relevant hardware in my system:
MoBo = ASUS PRO WS X570-ACE
CPU = AMD Ryzen 9 3950X
Graphics = ASUS AREZ-RX560-4G-EVO
Debian version is Bullseye following testing very closely.
Sorry I can't help you with this.
