wayland settings enfoce exclusive OR, enabling only one option and disabling the other
This is something that needs to be fixed/implemented in the Libinput library, not us. Please report it at https://gitlab.freedesktop.org/libinput/libinput/-/issues/ *** Bug 468851 has been marked as a duplicate of this bug. *** |
Created attachment 145306 [details] X11 settings SUMMARY I use "2-finger-scroll" and "edge-scroll" interchangeably in X11. But I cannot in Wayland STEPS TO REPRODUCE 1. Look at the respective settingspanels in screenshots OBSERVED RESULT Exclusive Or enforced by GUI in Wayland. EXPECTED RESULT X11 allows free choice. SOFTWARE/OS VERSIONS Operating System: Kubuntu 21.10 KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 Kernel Version: 5.13.0-23-generic (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-4700MQ CPU @ 2.40GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 4600 ADDITIONAL INFORMATION My touchpad is fine to support both for years now. 2-finger has the "advantage" of allowing diagonal movement impossible with edge-scroll. But edge-scroll allows for precisely keeping the vertical / horizontal position with pixel perfect precision. E.g. enlarge a PDF, so the lines stretch the window (especially pages with tiny-print multi-column text). Using 2-Finger, you will find yourself constantly cutting off either the first or the last few letters, because you inadvertently mixed a horizontal scroll-step in there. This is the perfect scenario for edge-scroll. E.g. open a map and follow a diagonal road off screen. This is perfect of two-finger-scroll, as with edge-scroll you need to alternate between horizontal and vertical portions of the way.
