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.

So far I have resorted to running "xinput set-prop "SynPS/2 Synaptics TouchPad" "libinput Natural Scrolling Enabled" 1" after every wake from sleep.
