I have tried installing Manjaro 20.2.1-210103 and 20.2-210207 with KDE to a Dell 7060. The install for both goes fine but when I reboot I see the Dell splash screen and then the monitor goes black and in to power-save mode. It initially seemed like the OS wasn’t booting at all.
After some testing I realised that if I typed my password after the monitor went into power-save mode I would be able to log in and the KDE desktop would appear, even though I never saw the log in screen. I also found that if it pressed Ctrl-Alt-F2 after the screen went into power-save made I would get a terminal prompt where I was able log in and run the DM with the startx command. This happened with both versions of the ISO I tried.
I can see some others with a similar issue with Gnome on Manjaro but this doesn’t seem to be fully resolved.
Can anyone assist with determining why the DM isn’t running when the system boots?
