It appears tyyS4 is constant among x200-t devices, as it worked for both of us. You could make it the default value and you could change if you encounter any new facts. Regards, RG.

The wacom device type is already the default. As inputattach can be used for many device types I would not want to change the default values to suit our specific needs. I don't even know whether the /dev/ttyS4 port is a constant among x200t thinkpads. Tim. [1] https://www.gnu.org/software/guix/manual/en/guix.html#Miscellaneous-Services

I will try S4 and get back to you. ☺ Btw, would you be able to set the default vaules of "device" and "device-type" to "/dev/ttyS4" and "wacom" respectively for "inputattach-configuration"?

No, you're not disturbing me. Feel free to ask.
It just happens to be, that I added inputattach to Guix because I also
needed it for the touchscreen on my x200-t to work.
My current configuration has
===
(service inputattach-service-type
(inputattach-configuration
(device "/dev/ttyS4")
(device-type "wacom")))
===
added to its services. Thats working for me.
If this does not fix the problem for you, than your touchscreen is
probably connected to another serial port:
- Use a tool of your choice to read the current text from one of the
serial ports ("/dev/ttySxxx" where xxx is any number).
- Point on your display with your pen. If random characters start to pop
up from the serial connection, this is the correct serial port.
- Replace your serial device with the one in my configuration.
Please note that this is a pretty adhoc approach that I added to Guix so
that it works for my setup, hoping that it could help others. When there
are issues or whishes concerning the documentation or if things just
don't work for you, please let me know.
Tim.

Thanks! I did use the above config but without the "device" and
"device-type" field. The error message I saw during system boot was
"InputAttach: Cannot set device type". So I am thinking the service did
actually detect the touchscreen of my x200-t, but could not set the
device-type??
But for sure I will try using your config as it is and let you know ☺

Sure ☺. Btw, could you expand/update the "inputattach-service-type" of
the Guix Manual, to include "inputattach-configuration" scheme
parameters/procedures and it's possible cum default values? Thanks!

RG.
