This will not work in Ubuntu 22.04 as it is running kernel 5.15 and Ubuntu did not backport the thinkpad keyboard patches to it.

The patches came in kernel 5.19. So you would need to use a newer version.

You can file a support case with Ubuntu to see if they will backport the patches to 5.15.

Ah. Oh not sure about the command tp-compact-keyboard .. but it's not able to see the keyboard properly when connected via bluetooth is likely.

If you look at the udev rules here under "disable fn-lock by default": https://github.com/lentinj/tp-compact-keyboard

You can see it has to do a trick for bluetooth connections that it doesn't have to do for usb connection.

Would say it's best to use the udev rule and then enable/disable manually.

How can I manually disable it

        echo Enabling native mode for F7/F9/F11 for /dev/$HIDRAW...
        /bin/echo -ne "\x18\x01\x03" | dd of=/dev/$HIDRAW 2>/dev/null

Is that so?

[jeroney]

For thinkpad 2 keyboards. You'll need to be root: echo 0 > /sys/bus/hid/devices/17EF:60e/fn_lock

For thinkpad 1 keyboards. You'll need to be root: echo 0 > /sys/bus/hid/devices/17EF:604/fn_lock

The udev rule is best. It will disable it on plug-in. Then you can control via keyboard.

How can I check if the driver is installed

[githublaohu]

Hello, I have three generations of TP compact keyboards, and the first generation settings are effective.

root@open:/sys/bus/hid/devices/0005:17EF:6048.0022# echo 1 > fn_lock
root@open:/sys/bus/hid/devices/0005:17EF:6048.0022# cat fn_lock 
1

Both the second and third generations failed

[githublaohu]

May I ask where the udev rules for TrackPoint Keyboard II can be found
