[systemsettings] [Bug 398713] [X11, Libinput] Selecting flat mouse acceleration profile doesn't turn off acceleration
https://bugs.kde.org/show_bug.cgi?id=398713 --- Comment #24 from warloxx...@gmail.com --- > flat acceleration just isn't the same as no acceleration. Actually it is exactly that. The name "acceleration factor" might just be a bit of a confusing name. Its just a factor that results from some acceleration calculation, and when not used gets set to 1 as to not have any effect (multiplicative identity element). A constant acceleration factor of 1 (Flat profile) will cause no acceleration. Since the factor really is just a proportional gain of mouse movement to pointer movement. If the term where 0 the pointer would not move at all anymore. This is basically a setting of how fast you want you pointer in relation to the movement of your mouse. The acceleration only happens when this term is not constant but depending on the current speed of you mouse movements. This happens in the adaptive profile. On higher mouse speeds the proportional term gets increased. This causes a fast movement of distance X resulting in a bigger pointer movement in the adaptive profile than in the flat profile. -- You are receiving this mail because: You are watching all bug changes.

Changing the options to: Acceleration: ꞏ Flat ꞏ Adaptive ꞏ Off or something similar would resolve the problem. I just hope the option to disable pointer acceleration won't get removed during future changes. -- You are receiving this mail because: You are watching all bug changes.

(ubunutu 19.04). And can confirm that the setting for acceleration never gets set in xinput just as described in comment 13. The setting is an bool array where only one is allowed to be true. But the code only has functions to store single values. That's why the setting is never applied. I made a draft of a solution in the attachment. It likely does not compile nor is up to snuff on code quality but should make the possible solution clear. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=398713 --- Comment #13 from Tom Seewald --- Looking at the output of "xinput list-props" between changes made in the kcm mouse menu, it looks like both acceleration radio buttons do nothing on X11. If you manually set the acceleration profile to "flat", you cannot set it back to adaptive using the GUI, and vice versa going from "adaptive" -> "flat". For reference acceleration is disabled when xinput list-props shows: "libinput Accel Profile Enabled (###): 0, 1" More information can be found on the arch wiki: https://wiki.archlinux.org/index.php/Mouse_acceleration#with_libinput -- You are receiving this mail because: You are watching all bug changes.

Output of libinput list-devices after clicking "Flat" shows that it does not change the libinput acceleration profile at all - it is still set to "adaptive". e.g. Device: Razer Razer DeathAdder Kernel: /dev/input/event2 Group:5 Seat: seat0, default Capabilities: pointer Tap-to-click: n/a Tap-and-drag: n/a Tap drag lock:n/a Left-handed: disabled Nat.scrolling:disabled Middle emulation: disabled Calibration: n/a Scroll methods: button Click methods:none Disable-w-typing: n/a Accel profiles: flat *adaptive Rotation: n/a The only way I've found to disable acceleration with KDE on X11 is to create a custom configuration file that sets it to flat.
