Comment 6 for bug 1984136

Per my investigation, this seems to be VERY complicated.

KDE Plasma writes its sddm settings, including autologin settings, to /etc/sddm.conf.d/kde_settings.conf
As far as I can tell, sddm.conf is left blank, but I don't know what is writing it as 'dpkg -S' is silent about it.

As it is, despite https://github.com/calamares/calamares/issues/1757, the code was never changed in calamares to allow it to point it to write to a different file *other than* /etc/sddm.conf, therefore it's hard-coded.

It *may* be possible to symlink /etc/sddm.conf -> /etc/sddm.conf.d/kde_settings.conf for an Ubuntu Studio installation prior to other sequences, but this may not be without risks. This may allow for calamares to write to the file properly to allow for autologin.

As it is, this will need testing on Kinetic prior to fixing in Jammy. Please test in Kinetic and report back.
