I have a Lenovo Thinkpad T450s with a trackpoint and a touchpad. Before upgrading to Ubuntu 21.04 I could disable the trackpoint on the terminal with the command
xinput set-prop "TPPS/2 IBM TrackPoint" "Device Enabled" 0
After the upgrade this does not work anymore and I get a message
WARNING: running xinput against an Xwayland server. See the xinput man page for details. unable to find device TPPS/2 IBM TrackPoint
shows that the device "TPPS/2 IBM TrackPoint" is not there anymore.

If I attempt to disable any of the devices listed, it does not have the desired effect of disabling the trackpoint device. Is there a way to disable the trackpoint when using Ubuntu 21.04 from the terminal, preferrably without having to edit any configuration file and without having to reboot? If yes, how can this be done?
