Description of the issue (screenshots if relevant):
Booted and installed the Plasma6 Slim edition (x11, x86_64). The Live ISO booted and went to the desktop with no issue. Installed to a clean drive (zeroed out partition table beforehand). Rebooting to the default GRUB setting, the system never loads the GUI (even leaving it for 30 minutes). If I boot the system into console mode, it will boot to command line fine, and I can start the GUI with “startx”

This is a test machine, so I can tweak or reinstall as needed
I’m going to blame the known intel driver bug, then. You can try the server kernel and report back if that resolves it. @bero might know why that is a problem in the desktop kernel.
So I’m wondering if I should pull some debug data for Plymouth and/or sddm, which seem to be the two possible failures. Since enabling an autologon lets the system proceed to the Plasma6 desktop, I’m wondering if the autologon completely bypasses sddm or is it still running part of that display manager.
Just to check that it wasn’t just a matter of sddm having to run correctly once, I disabled autologon. And it returned to the prior state of not loading the UI.
No change. Installing the full Plasma6 (as well as the LXQT iso) fail to load the GUI.
From the blank screen I get after the initial boot process finishes, I switched to the second terminal window (-) and ran ‘sudo systemctl restart sddm’, which brought up the GUI. However, if I run ‘sudo systemctl stop sddm’, the first terminal window will still be blank (it doesn’t drop to a command line login) but ‘sudo systemctl start sddm’ in the second terminal will start the GUI.
