Hi!

I have installed (Manjaro) LInux with KDE (that is all software is almost the latest stable one) on HP ProBook 450 G5, and all works fine except for a single problem. After system restart and KDE starting a touchpad is working partially. That is two-fingers and three-fingers emulation of the second and the third mouse buttons isn't working, and appropriate settings in System Setting are disabled. But single tap is working as the first button click. After KDE restarting all is OK. At the moment I have got

Code: Select all

>>> cat 30-touchpad.conf                                                                                                                                                                                                             
Section "InputClass"
        Identifier "MyTouchpad"
        MatchIsTouchpad "on"
        Driver "libinput"
        Option "Tapping" "on"
        Option "HorizontalScrolling" "0"
        Option "Accel Speed" "0.26"
EndSection


Without this file even the first button click doesn't work after system restart. That is touchpad isn't emulated at all, and I'm forced to use laptop's clickpad as clickpad. At this case ( that is without this X11 config file) KDE restart also results in all working.

How to make all working just on KDE start?

Oops... It seems

Code: Select all

    Option "TappingButtonMap" "lrm"


does the trick.
