SUMMARY While installing any KDE distro You select a time zone (Let, Iceland/Germany/Philippines), then in post-installation configuration you change days, months etc locales when needed. To take into effect, you logout then login again. This changes the locales your system wide except the login screen. The login screen keeps alphabets of days, months in the preconfigured settings. Every reboot shows same. But if you lock/sleep the session & the login screen appears, you would never see it there. Only you logout & on the login screen, you can see it. I tested on Kubuntu 20.04 & Manjaro(KDE) 20.0.1 e.g like this pic...(https://imgur.com/a/tZpXotB) when I accidentally selected Iceland time zone by installer & post-installation configuration selected english but that did not change the alphabets on login screen. STEPS TO REPRODUCE 1. Select through any installer. 2. Change post-installation settings 3. logout & re-login OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Kubuntu 20.04 & Manjaro 20.0.1 Windows: macOS: Linux/KDE Plasma: Yes (available in About System) KDE Plasma Version: 5.18.04 KDE Frameworks Version: 5.68 Qt Version: 5.12.8 ADDITIONAL INFORMATION aslo applied to Manjaro KDE
Update to latest KDE Plasma 5.18.5 did not resolve the problem.
This is indeed a problem. I already tried to add locale settings to the list of things that can be synced from Plasma but unfortunately I believe I could never override /etc/locale.conf. The locale settings module could have an option to apply settings globally instead of just for the current user.
Any progress on this?
SDDM reads /etc/default/locale to set language/regional settings https://bugs.kde.org/show_bug.cgi?id=428590
I've received a report downstream in Fedora about this: https://bugzilla.redhat.com/show_bug.cgi?id=2177257 It'd be great to see some progress on this and bug 428590 at some point.
