Now this happen again. I got screen #2 as primary and screen #1 was not in use
(invisible for GPU). I did reboot many times without success. I did power off
and disconnect electricity socket without success. Then I booted from Windows
and it works with both displays, then I booted from Ubuntu 26.04 and it works
with both displays too. Crazy
