When I set my mouse setting to left-handed, this setting is ignored upon reboot of my system. I have to re-apply the setting in order for my mouse to act left-handed. The setting is shown correct in the desktop settings menu, but it applies the default setting after rebooting. Reproducible: Always Steps to Reproduce: 1. Under "Input devices" change mouse from right-handed to left-handed 2. Apply settings, all is well. 3. Reboot system, mouse setting is back to default 4. Open "Input devices" again, notice setting is shown correct, but not applied. Need to change the setting again in order for it to be applied. Actual Results: After reboot mouse is set to default. Expected Results: All settings as applied in the "input devices" menu to be applied after a reboot of the system.
Just one question: What KDE Frameworks version are you using? We had a similar bug report in openSUSE a while ago: https://bugzilla.suse.com/show_bug.cgi?id=936419 As mentioned there, it works fine for me with the latest versions (you do have Plasma 5.3.2), but I was able to reproduce it with older ones (Plasma 5.3.1/KF 5.10 in particular). And please, also make sure that you use systemsettings5, not KDE4's systemsettings. The latter will apply the setting in the running session, but saves it in the KDE4 location (~/.kde4/share/config/) that is not respected by Plasma5.
KF is at 5.11. My install was a fresh 13.2, without a user profile created. Plasma 5 was the only desktop selected during install.
I removed my user. Removed kde4. Re-Installed plasma 5 and created my user again. Settings are now applied correctly after reboot. It may be some setting conflict that I'm not aware of. I'll mark it as resolved.
