Keep this Biometric Trojan Horse BS out of my KDE please. Not only is it the only password you can never change if it gets compromised, but I can probably lift your fingerprint from a glass with scotch tape and use it.
Would be cool if the SDDM replacement also functions as the Plasma lock screen, and takes over when you lock your user session. The current user switching experience is pretty awful.
As someone who runs multiple desktop sessions at once, each on a different virtual console, sddm is a continual pain in my workflow. Notably:
It assigns desktop sessions to virtual consoles inconsistently, and has no way to manually configure them, so Control+Alt+FN often switches to a session that's not the one I wanted. The assignments can change from day to day or any time a session logs out and back in. This makes using multiple desktops a constant pain.
I don't know for sure, but I suspect it is behind the graphical glitch that makes the desktop session unlock screen draw incredibly slowly on KDE 5. Having to wait several seconds for each character in my passphrase to register is an annoying waste of time.
im not up on the latest lore admittedly but looking at the github repo, it seems there has been little activity in terms of new code. Its also not well integrated with KDE despite it being primarily used by KDE Plasma.
