The bug is quite the same, as #26518 I just wasn't sure if I should open a new one or reopen the old one. Quote from there, with a little changes: The mouse settings set using KDE Control Center (Peripherals/Mouse) are not applied after logging in via kdm. The settings are properly saved in ~/.config/kcminputrc: [Mouse] Acceleration=2.5 MouseButtonMapping=LeftHanded ReverseScrollPolarity=false Threshold=4 and they work as expected immediately after changing the settings but after logout and login the mouse is back at the default behavior and you have to go to the control center and push the "Apply" button again to get the desired setup. Important for me is "LeftHanded" flag. I tried it with a new user and on another laptop - the bug persists.
...KDM? Does it work with SDDM? Libinput or evdev?
(In reply to Nate Graham from comment #1) > ...KDM? Does it work with SDDM? Libinput or evdev? I'm using KDE Neon with default input and DM libraries: evdev and SDDM.
Neon dev or Neon user? Are you sure you don't have Libinput installed? Do you have xserver-xorg-input-libinput-hwe-16.04 installed?

Ok, you're using evdev, then.
It's a two years old installation, which was regularly upgraded. This problem exists after the last big one, in Plasma 5.13.
I can confirm this. I am having the same problem.
Current Workaround can be found here till the bug gets resolved: https://askubuntu.com/questions/1047325/mouse-button-order-gets-reset-after-restart

I should note that whatever is causing the settings to not be applied doesn't seem to affect kwin_wayland, at least as far as the left handed setting is concerned.
Bug Still exists in Plasma 5.13.5, Applications 18.08.1
Git commit a4c724173b5c6a59331587f2e5db746dffbabdc6 by Roman Gilg. Committed on 12/09/2018 at 17:29. Pushed by romangilg into branch 'master'. [Mouse KCM] Avoid changes to touchpads in libinput backend Summary: Similar to evdev backend we need to ignore touchpad devices explicitly in the libinput backend because these are also pointer devices. XInput2 can do this in theory via input classes, but my touchpad did not set the class correctly. So just switch to using XInput like in the evdev backend to query all pointer devices and then use the XI_TOUCHPAD atom to filter out touchpads.

(In reply to Jacopo Torrini from comment #19) > Bug still exists in Plasma 5.14.0 Way to reproduce: open mouse system settings. Click the Invert scroll direction checkbox. Mouse whell scroll is reversed. Reboot. In mouse systemsettings checkbox is checked but mouse whell scroll is not reversed.
:(
Bug still exists in Plasma 5.14.1
Bug Still exists in 5.14.2
> Way to reproduce: open mouse system settings. Click the Invert scroll direction checkbox. Mouse whell scroll is reversed. Reboot. In mouse systemsettings checkbox is checked but mouse whell scroll is not reversed. Another way to reproduce: My mouse is bluetooth usb mouse, pulling the receiver out then plugging it in will make its settings reset to default.
Bug still exists in 5.14.4. Has there been any progress in tracking it down?

[kcms/mouse] Load current server settings in kcminit Summary: Without loading the current server status m_handed will remain Handed::NotSupported; EvdevSettings::load relies on various properties of X11EvdevBackend to be initialised properly. When we load the settings from the config it'll then save the fact that the server doesn't support setting which hand mouse to use as none was loaded - and assume that means we probably can't apply any setting.
