At the moment one has to change the option "ServerArguments" in sddm.conf to make sddm scale correctly when using a HiDPI display: [X11] ServerArguments=-nolisten tcp -dpi 192
The more elegant approach would be to not need to do this song-and-dance at all; SDDM should be able to detect the DPI itself, or we should pass it along automatically.
>?SDDM should be able to detect the DPI it Surprisingly complex, but yes, that's the way to go. I'm not adding a GUI option for arbitrary command line args. If you can modify command lines you can modify a config.
Do we have an SDDM bug report tracking that already? Or is it imminently planned such that there's no need for one?

Yes, for me personally it would only be convenience. But what about novice users who are no command line experts? Maybe instead of the whole command, just add an option for changing the DPI like the one in kcm's font config menu? (that then gets translates into the command line behind the scene)
