KDE DM not loading on fresh install

Hi,

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?

Thanks

Having plugged a second monitor into my desktop, I still have the same issue but I now notice that sddm-greeter appears once I have logged in as shown in the screen cap. I can close this and continue with my work but just adds to the annoyance I would ideally like to resolve. I have not had similar issues with other distros on the computer like Kubuntu.

Thanks
