Just want to report that I have installed 5.6.0-0.bpo.2-amd64 from
buster-backport and now the display can be powered back on when I
pressed my keyboard or moved my mouse.
I do not see any other problems right now, everything seems to work
fine, except one error message in dmesg everytime the display goes the
off-on cycle:
broken atomic modeset userspace detected, disabling atomic
But I guess it's a different problem and it doesn't seem to cause any
problem.
