f42 x86_64 with all updates, i915 built in video
I have a problem where when I disconnect a monitor (e.g. using a KVM) and reconnect, the screen remains blank.
I checked the situation and running 'xrandr --listmonitors' shows the monitor is initially disconnected and then connected.
So Xorg thinks all is well, but I get no video (maybe an intel x11-server issue?).
Does it work if you use Wayland desktop?
I can switch to text (e.g. tty2) which works fine (is visible), but when switching back to tty1 the screen is blank.
Running 'xrandr --output HDMI1 --mode 3840x2160_24.00' revives the video. However it should run from a graphics session
(an xterm window on :0 on tty1 in my case).
Can I, somehow, issue this command from a text VT? For example start 'xterm' on tty1 (from tty2)?
Try like this:
XAUTHORITY=/run/user/1000/xauth_icQwML DISPLAY=:0.0 xterm
You will need to figure out what the XAUTHORITY file path is each time Xorg is started.
