KDE Plasma forgets about left handed mouse mode after mouse reconnect

My mouse is connected through usb hub in display. I have swapped mouse left-right buttons in plasma settings (left handed mode). When I turn display off mouse disconnects. When I turn display back on left handed mode check box is still on, but mouse returns to right handed mode.

Using "xinput list-props" command I found that after reconnect mouse have "libinput Left Handed Enabled (307)"  set to 0 instead of 1

This started to happen week ago. What could be cause of this bug?

Re: KDE Plasma forgets about left handed mouse mode after mouse reconnect

I had this issue myself and it seems to be a bug with KDE. I fixed it by manually creating /etc/X11/xorg.conf.d/10-libinput.conf and configured it to explicitly be set to left handed mode.

Section "InputClass"
    Identifier      "Logitech G Pro Left Handed Mapping"
    MatchProduct    "Logitech G Pro"
    Driver          "libinput"
    Option          "LeftHanded" "1"
EndSection

Get the MatchProduct with

xinput list

and append both the Identifier and MatchProduct line to yours. It should work after restarting the X server.

Re: KDE Plasma forgets about left handed mouse mode after mouse reconnect

Same issue over here. Probably a KDE bug. After every resume (sleep/hibernate/boot) I need to go to settings, disable Left Handed Mode, apply and enable Left Handed Mode again.

I tried the xorg conf, but it doesn't work:

[jvlek@rick-sanchez ~]$ cat /etc/X11/xorg.conf.d/10-libinput
Section "InputClass"
    Identifier      "MX Anywhere 3 Mouse Left Handed Mapping"
    MatchProduct    "MX Anywhere 3 Mouse"
    Driver          "libinput"
    Option          "LeftHanded" "1"
EndSection

My system info:

Operating System: Arch Linux
KDE Plasma Version: 5.24.2
KDE Frameworks Version: 5.91.0
Qt Version: 5.15.2
Kernel Version: 5.16.10-arch1-1 (64-bit)
Graphics Platform: X11

I can file a bug at KDE later this weekend.

Sorry for the late reply, did you add .conf to the end of the file, otherwise it won't work. So it should be /etc/X11/xorg.conf.d/10-libinput.conf instead of /etc/X11/xorg.conf.d/10-libinput.
