Description hellogaming91 2025-07-16 19:21:53 UTC 
SUMMARY
Autologging into Plasma doesn't work despite configuring it like in SDDM.

STEPS TO REPRODUCE
1. Try any of these locations: /etc/plasmalogin.conf (specified in the README) /etc/plasma-login.conf (the KCM writes this) /etc/plasmalogin.conf.d/autologin.conf (This worked with SDDM)
2. Add these lines (replace username with the logged in user)
[Autologin]
User=[username]
Session=plasma
3. reboot

OBSERVED RESULT

It launches into the login screen instead of the desktop

EXPECTED RESULT

It launches into the desktop

SOFTWARE/OS VERSIONS
Linux: Arch Linux
KDE Plasma Version: 6.4.3
KDE Frameworks Version: 6.16.0

ADDITIONAL INFORMATION

Since this is an SDDM fork, and I configured it like this in SDDM, I expected it working

It seems to require adding .desktop after the session name, it won't work otherwise. (and it only works with /etc/plasmalogin.conf from my quick testing). I suspect this commit broke it: https://invent.kde.org/plasma/plasma-login-manager/-/commit/2f4286c6c266209590c710994f8350314a2fda5b.patch
