Turns out I had nomodeset parameter on the kernel command line (in 
GRUB), because I installed Fedora 36 using "basic" graphics mode. Normal 
mode resulted in a blank screen for me during Fedora instalation.

Then I had a problem with nouveau showing a stack trace in dmesg, 
because I connected an HDMI monitor (DELL U2722D) using an USB-C to HDMI 
adapter (see bellow). This has triggered crash notifications on my 
desktop and is reproducible. Probably the reason Fedora installer 
required "basic" graphics mode.

Thank you,
