SUMMARY Synchronizing Plasma settings to SDDM results in an invisible cursor in SDDM (wayland mode): STEPS TO REPRODUCE 1. Set some cursor size in plasma settings 2. Synchronize to SDDM 3. Restart OBSERVED RESULT We get: CursorSize= in /etc/sddm.conf.d/kde_settings.conf EXPECTED RESULT We should get: CursorSize=24 in /etc/sddm.conf.d/kde_settings.conf SOFTWARE/OS VERSIONS Linux/KDE Plasma: Gentoo linux (available in About System) KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.2 Qt Version: 6.6.2 ADDITIONAL INFORMATION Manually specifying the correct cursor size resolves the invisible cursor problem. A second related bug is probably that an empty setting should be considered invalid.
Already fixed in 6.0.3: https://invent.kde.org/plasma/sddm-kcm/-/merge_requests/67
