https://bugs.kde.org/show_bug.cgi?id=514391 --- Comment #13 from Szczepan Hołyszewski --- If this bugtracker supports it, consider adding "depends on" 515392. I reported the currently experienced symptom as a separate issue, and I can't properly test the fix to this issue until that one is also fixed. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=514391 --- Comment #12 from Szczepan Hołyszewski --- Why is this issue stuck in NEEDSINFO/WAITINGFORINFO? I was asked to try a particular fix. I did so, and provided feedback already on Jan 10: TL;DR the fix makes things strictly worse. -- You are receiving this mail because: You are watching all bug changes.

This now can't log me in at all. Greeter shows, but no pointer, no reaction to input, and crashes/exits all by itself after a while. ``` -- Boot 95794f7536104141b334809576cd759b -- Jan 14 14:20:40 berbelek plasmalogin[1076]: Initializing...

https://bugs.kde.org/show_bug.cgi?id=514391 --- Comment #3 from Szczepan Hołyszewski --- (In reply to Oliver Beard from comment #2) > This doesn't happen on my Arch Linux install. Is this using the AUR package? > After login, TTY1 shows the systemd bootup and TTY2 shows the login session. > There is never any console login prompt. AUR package `plasma-login-manager-git`. I might have done some TTY/console tweaking in the past and I may have things running on TTY1 that doesn't run there in a stock Arch. But this probably only surfaces the issue rather than causes it. With SDDM, TTY1 has black screen with mouse pointer, TTY2 has console login (no password leaking there), and TTY3 runs the Plasma session. With plasmalogin, TTY1 has what the screenshot shows, TTY2 has whatever desktop session plasmalogin starts, and TTY3 has console login prompt. I vibecoded a script that gathers some diagnostics and ran it both in a SDDM session and in a plasmalogin session. Attaching the diagnostics. In any case, I believe a proper greeter should prevent keyboard input from spilling over. -- You are receiving this mail because: You are watching all bug changes.
