libinput list-devices

Description of problem:

(I've chosen libinput as the "faulty" component ; it could be something related to mutter though).

I've installed F34 on a Thinkpad X1 tablet 1st gen. With the trackpoint working (= after disconnecting/reconnecting the keyboard or a suspend (s2idle) / resume cycle), disabling the touchpad in Gnome/Wayland also disables the trackpoint, while disabling the touchpad in Gnome/Xorg works as expected - ie. the trackpoint is functional.

I've tried a few ways to turn the touchpad off, but they all result in the trackpoint also being disabled:

- toggling the touchpad in gnome settings GUI or its likely cli alternative `gsettings set org.gnome.desktop.peripherals.touchpad send-events 'disabled'`

- creating a libinput quirk (I couldn't find what "AttrEventCodeDisable" name to use; I've tried with BTN_RIGHT for tests but I could still right click with the touchpad so it didn't have any effect).

[Lenovo X1 Tablet 1st gen]
MatchName=Synaptics TM3203-003
MatchDMIModalias=dmi:*svnLENOVO:*pvrThinkPadX1Tablet:*
AttrEventCodeDisable=BTN_RIGHT

- writing a udev rule to ignore the touchpad

ACTION=="add|change", KERNEL=="event[0-9]*", ENV{ID_VENDOR_ID}=="17ef", \
        ENV{ID_MODEL_ID}=="6085", ENV{ID_INPUT_TOUCHPAD}=="1", ENV{LIBINPUT_IGNORE_DEVICE}="1"



Side note: I'm not sure if it's related or if I should open another bug, but there's no palm detection when both the touchpad and the trackpoint are on; eg. I can move the pointer up/down with the touchpad while moving it sideways at the same time with the trackpoint (which should not be the case as described in https://wayland.freedesktop.org/libinput/doc/latest/palm-detection.html?highlight=palm#trackpoint-disabling).

Version-Release number of selected component (if applicable):

libinput-1.18.1-1.fc34.x86_64
mutter-40.4-1.fc34.x86_64
gnome-shell-40.4-1.fc34.x86_64


How reproducible: always


Steps to Reproduce:
1. boot and log in with a Wayland session
2. disconnect/reconnect keyboard cover or do a suspend/resume cycle to enable the trackpoint (issue https://gitlab.freedesktop.org/libinput/libinput/-/issues/487)
3. disable the touchpad

Actual results: trackpoint should work.

Expected results: trackpoint is disabled.

Additional info: disabling the touchpad works in Windows 10.
