Morning, As you can see on the screenshot, all options are greyed out into panel of Touchpad configuration. That is the same comportment for taps | scrolling | Pointer motion and others. It's not possible to configure any option Mouse (using touchpad) is working as usual, double toes for a right clic, etc. but no configuration are possible. Nothing crash. I'm using plasma-desktop 5.6. Cheers, Antoine P.S. Please apologize my language, it's not my native language. Reproducible: Always Steps to Reproduce: 1. Open your plasma session ; 2. Go on System Setting > Hardware > Touchpad ; 3. See that all options are greyed out.
Hi, The reason these options greyed out is you (or the distribution) is using/installed the 'new' libinput touchpad driver. The package name is usually xorg-x11-drv-libinput. Libinput is the unified touchpad driver for X.org and Wayland; but it exposes only few configurable options compared to the 'old'/previous synaptics driver (package xorg-x11-drv-synaptics). If you want all the options to be individually configured, simply remove libinput driver and install synaptics driver.
Hi, Thank you for replying. Actually I see "synaptics" and "libinput" driver are both used. - x11-driver-input-libinput - x11-driver-input-synaptics If I try to remove libinput driver, task-plasma-minimal and task-X11 have to be removed (I didn't make it, I'm trying to understood how work xorg.conf). And if I try to remove Synaptics driver, I should remove x11-driver-input. Into /etc/X11/xorg.conf.d I see : - 50-synaptics.conf - 90-libinput.conf I'm not really comfortable with this manipulation. Thanks again, i'll search how-to. Maybe this bug can't be closed. Cheers. :-) antoine
I only have renamed 50-libinput-conf to 50-libinput-conf.old and all greyed out option are now available.
If both drivers are installed, libinput gets the preference. Either you can change the priority similar to comment#3 or simply uninstall the driver you're not using. Touchpad KCM cannot do anything on its own, so closing the bug.
