I recently put a new machine together using an AMD Radeon PRO W6600 Graphics
Card. CPU is a threadripper pro. Motherboard is an ASUS Pro WS WRX80E-SAGE SE
WIFI II sWRX8 E-ATX. Software is the KDE spin of Fedora 37.
It mostly works perfectly, but if I try to access a virtual terminal with
Ctrl-Alt-F3 my monitors go to sleep, so apparently the video sync shuts off.
Typing Ctrl-Alt-F2 brings me back to my KDE session.
Also Ctrl-Alt-F1 shows me the text that occurred during boot - I have rhgb and
quiet disabled in my grub configuration. So Ctrl-Alt-F1 and F2 work, but F3
and above do not.
I don't see anything in /var/log/messages that would give me a hint as to where
to start with debugging this. I've tried running SDDM in wayland and in x11
modes, but that doesn't make a difference.
I'd like to write a bug for this, but I'm not sure how to gather enough data
for a meaningful report. Are there some kernel options I can try, or other
ways to get more data?
