Bug ID: 427771
Summary: Flat/Adaptive pointer acceleration setting does
nothing on wayland
Product: systemsettings
Version: 5.20.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_touchpad
Assignee: plasma-b...@kde.org
Reporter: kdeb...@fratti.ch
Target Milestone: ---
Launching a Plasma Wayland session and going into the touchpad settings, one
can change the flat/adaptive radio button option for pointer acceleration with
no effect. In fact, hitting apply shows the options as immediately being
reverted back to its previous state. The same appears to apply for natural
scrolling, which seems to be forced on for some applications on Wayland, even
if the settings show it as being off.
STEPS TO REPRODUCE
1. Open system settings -> touchpad
2. Click on "Flat" instead of "Adaptive"
3. Hit "Apply"
OBSERVED RESULT
Pointer acceleration remains, GUI immediately reverts to the option "Adaptive"
being checked
EXPECTED RESULT
Setting is actually changed
SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.20
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1
ADDITIONAL INFORMATION
Works fine on X11, also using libinput.
Occasionally, the "Adaptive" or "Flat" choice doesn't show up at all; in those
cases, clicking on some other settings menu then going back makes it appear.
Weird. This also happens on X11 sometimes, though.
