Bug ID: 456383
Summary: Inertial scrolling is not supported with libinput
Product: systemsettings
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_touchpad
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
It is impossible to enable kinetic scrolling in KDE with libinput driver in
System Settings.
We know that libinput driver does not implement inertial scrolling for
touchpads, see
https://wayland.freedesktop.org/libinput/doc/latest/faqs.html#kinetic-scrolling-does-not-work.
Synaptic's driver "implementation" is just a crutch: it just keeps sending
scroll events when you do swipe by fingers. But it does not care what is going
on in the desktop, and causes some unfixable bugs.
We need a proper implementation in KDE.
STEPS TO REPRODUCE
1. Go to System Settings, Input Devices, Touchpad.
2. Search for Inertia Scrolling checkbox
OBSERVED RESULT
There is no such checkbox
EXPECTED RESULT
The checkbox should be available.
SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.25.2
KDE Frameworks Version: 5.95.0
Qt Version: 5.15.5
Graphics Platform: Wayland
ADDITIONAL INFORMATION
Bug 443819 (for okular), Bug 403285 (for konsole) - fixes for synaptics'
implementation (ignoring ctrl while scroll events are sent).
