No Display Signal when booting RHEL without display connected

Latest response

Hi Everyone,

A bit of a strange one here that I have been searching the internet for help.

I install RHEL 8.4 on a machine with a monitor connected, installation is fine, RHEL works perfectly, I can disconnect the display and reconnect it and everything is fine.

However, if I shut the system down, disconnect the display, power up the system and then later connect the display, RHEL doesnt seem to detect the fact that I have connected a monitor, the machine is on the network, I can SSH to it, but I am not able to get the display to work unless I reboot with it conncted.

Any thoughts or ideas??

Thanks

Mike
