Since I installed Debian11, it happens from time to time (generally when
I leave the system unattended), that everything freezes:
keyboard and mouse.
I found on several blogs some silly recommendations, involving typing
something. I say "silly" because in that case in I can't do anything:
neither with the keyboard nor the mouse
when I say "frozen" it means "frozen" (may-be "dead" would be a better
word, as the computer doesn't answer to ping)
and the only thing I can do is reboot, being after that obliged to
re-install.
I tried running the screensaver,but the problem remained.
Has anybody a solution?
Thanks in advance

Hello, the issue you describe is very often hardware specific, so giving
as many information as possible will increase the possibility to "ring a
bell" with someone on this list. The most common I have seen are bugs in
some CPU sleep state, graphic driver that crash and put the graphic
server in an irrecoverable state and lock up the GPU. Huge memory leak
in a program can also lead to what you describe, if the kernel oom
doesn't kick in or does but kills an essential part of the session.
Did you try to look into your system logs at a time right before the freeze?
