--- Comment #7 from [email protected] --- I've done some more digging on this now, from what I can tell the problem here is that the KDE disable touchpad toggle is disabling a device group which includes the trackpoint when it should simply be suppressing the input from the touch pad, which is what the "xinput float 11" command I used to be able to use was doing I tried various approaches to work around this on the command line, with UDEV rules to disable devices, but this caused the same problem, they disabled both touchpad and trackpoint. The only workaround I have found that works is to create a custom systemd service that uses the evtest tool to grab the input from the touchpad as a way of suppressing it: [Unit] Description=Grab Synaptics touchpad events After=multi-user.target [Service] #ExecStart=/usr/bin/evtest --grab /dev/input/event6 ExecStart=/usr/bin/evtest --grab /dev/input/by-path/pci-0000:00:14.0-usb-0:7:1.2-event-mouse Restart=on-failure RestartSec=2 StandardOutput=null [Install] WantedBy=multi-user.target This will work with both the numbered event node (commented out) or the more stable device name. So I think what needs to happen is for the "disable touchpad" toggle in KDE to identify the input that receives touchpad events and to ignore it instead of trying to disable underlying devices which can have unintended side effects. -- You are receiving this mail because: You are watching all bug changes.
