I'm not an expert, so I thought that the error by the time could be a issue in
video driver.

The last kernel was 5.8.1.arch1-1. It was upgraded last sunday.

I left mypc 2 hours unattended and when I typed the password in the monitor
that before remained black (I can see the password input window), now has the
same issue.

I searched on journalctl and I didn't see the same error. If fact I don't see
anyhing important.

I tried executing:

xrandr --auto --output VGA-1 --mode 1280x1024 --right-of DVI-D-1

and the desktop swap monitors, but the monitor black still remains black.

It could be a hardware error. How can I know if is a hardware error?

Regards
Oscar
