SUMMARY I changed the mouse and the mouse wheel scroll speed is too low. There is no Advanced tab under Mouse to change it. STEPS TO REPRODUCE 1. G to system settings, Input devices, mouse. 2. No way to change the wheel scroll speed. 3. OBSERVED RESULT No way to change. EXPECTED RESULT Dialog to change wheel scroll speed. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.20.04 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION
You must be using the Libinput driver on X11. This feature cannot be implemented for this use case due to lack of support in Libinput itself. See https://gitlab.freedesktop.org/xorg/driver/xf86-input-libinput/-/merge_requests/12 We have to wait for that issue to be fixed in Libinput before we can add the feature. On Wayland the situation is different, and we have already implemented a scroll speed feature. Another alternative is to remove Libinput on X11 and use the older evdev drives, which do have this feature.
