Bug ID: 400069
Summary: Touchpad scroll direction does not persist after sleep
(libinput on X11)
Product: Touchpad-KCM
Version: unspecified
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Touchpad scroll direction not persistent after sleep when using libinput
drivers on X11
STEPS TO REPRODUCE
1. Ensure laptop uses libinput drivers for the touchpad
2. Navigate to System Settings -> Input Devices -> Touchpad -> Scrolling
3. Check "Vertical" under "Reverse Scrolling"
4. Apply settings
5. Put laptop in sleep mode
6. Resume from sleep
OBSERVED RESULT
After initial application, the scrolling direction is reversed, as expected.
After resuming from sleep, the scrolling direction reverts to the original, and
the checkbox mentioned above becomes unchecked. Re-checking it does not trigger
the "Apply" button to become clickable. It must be unchecked again (now the
"Apply" button triggers), applied, and then re-checked and reapplied to
re-enable reverse scrolling.
However, the setting does persist between reboots, logouts, and shutdowns.
EXPECTED RESULT
The scroll direction reverses and persists after sleep.
