I've recently upgraded my display to a high-refresh one. This is the only
change.
Now every now and then, the screen will randomly go black without displaying no
signal. There's no patter to it - it may happen after SDDM login, it may happen
when waking the display up, or it may happen while I'm doing something.
When this happens, I can press Ctrl-Alt-F3 to go to the console, which displays
just fine, and then go back to F2 where the black screen is - now there will be
a CROSS (like taskkill) but nothing happens. In very rare cases, switch to
console and back will revive the display, but it never does.
Since the issue is very random, I cannot provide any exact steps to reproduce
it.
It only happens in high refresh rate modes, i.e. 240 or 360hz. Using the same
display in 60 or 120hz mode, or another machine with AMD GPU and 144hz display
never has these issues.
I also suspect its a Wayland issues, and X11 does not have it.
There is nothing wrong with the display, as I can use it in Windows for hours
and it works perfectly.
I'm not sure this is the right Product/Component, please move it accordingly.
