I have very stange things after upgrading to Fedora 37. On Fedora 36 I
had troubles after waking up displays from power save mode, such as
loosing positions of windows, panels and widgets. After upgrading to 37
my middle display, connected to DP, won't start at all after powersave
and I have massive visual glitches on left and right displays. By
pressing Ctrl+Alt+F12 and disabling graphic effects, glitches are gone,
but I still can't enable main display. I try to enable this display
manual via kscreen settings, but with no luck. Sometimes, I can do that,
but almost - no. When I reboot my PC, middle display stays disabled.
Only what I can do - is switching to Wayland, reconfiguring displays and
start Xorg again. After this, display works as expected until next
powersave. Another strange thing: after I have this bug, when I try to
logout from KDE to switch to Wayland, SDDM freezes. But it is shown on
all displays
