SUMMARY I have switched to evdev for mouse by adding a configuration file in /etc/X11/xorg.conf.d/, but Mouse KCM still thinks I am using libinput. I have to also switch to evdev for keyboard to make Mouse KCM displays the evdev set of options. STEPS TO REPRODUCE 1. Apply the following configuration: Section "InputClass" Identifier "evdev-mouse" MatchIsPointer "yes" Driver "evdev" EndSection 2. Log out and log in again 3. Mouse KCM still in libinput mode 4. Change the configuration to (add the keyboard section): Section "InputClass" Identifier "evdev-keyboard" MatchIsKeyboard "yes" Driver "evdev" EndSection Section "InputClass" Identifier "evdev-mouse" MatchIsPointer "yes" Driver "evdev" EndSection 5. Log out and log in again 6. Mouse KCM finally switches to evdev mode ADDITIONAL INFORMATION On Arch Linux, xorg-server depends on xf86-input-libinput, so it cannot be removed.
> On Arch Linux, xorg-server depends on xf86-input-libinput, so it cannot be removed. Sounds like a packaging problem to me. :) This isn't a problem on other distros, so I would recommend that you get into contact with the Arch packagers about it.
From /var/log/Xorg.0.log, I confirmed that it is possible to use evdev only for the mouse, but KDE incorrectly thinks that libinput is used, and settings like left-handed mode is not applied. Arch Wiki also says that alternative drivers for Xorg#Input devices can generally be installed in parallel. [1] [1] https://wiki.archlinux.org/index.php/Libinput#Via_Xorg_configuration_file
Ah, perhaps you're right.
Hello! This Bugzilla ticket concerns support for the non-Libinput version of the Mouse page, which is no longer supported in Plasma 6. As such, the ticket will be closed as fixing or implementing what's requested here is now out of scope. Thanks for your understanding!
