Sorry for the late reply. Based on the conversation between me and Mark, the fprintd now works. You will have to add "(gnu services authentication)" in "use-modules" and "(service fprintd-service-type)" in "services"; of system config.

What and how should I do to enable the following in my Thinkpad

I just got an X230T so I'm very interested in getting the same
1) Buttons on the lid like screen rotation, lock screen etc.
Those buttons act like special keys on your keyboard. The
page lists their scancodes, and gives some advice on how to set
up so that the buttons behave as expected:
The page recommends using xbindkeys, which is provided by the
"xbindkeys" package, but depending on which desktop environment
there might be a more straightforward way to arrange for a
script to be
run when you press a key.
Exactly. I used ‘xev’ (available in Guix) to get the keycode for
what I presume is the screen rotation button(? there are two, the
pictograms are pretty vague, but only one generates classic key
codes) and added
bindsym XF86TaskPane exec --no-startup-id
to my ~/.config/i3/config. rotate-screen.sh is a simple (well…)
shell script that uses xrandr to query the current screen
orientation and cycle to the next one (I use left/right/normal,
xrandr --output LVDS-foo --rotate normal|left|right|...
The only problem is that pressing the button once produces a
deluge of press events. Luckily the number is usually constant
(so it's not just a ‘repeat’ without a ‘delay’) making the end
result predictable. In practice it means I'm cycling backwards
through the orientations.
Good enough for now. It's not like I can actually use i3 properly
in tablet mode anyway. Will this finally push me to GNOME?
2) Input using stylus pen.
The touch screen is apparently a Wacom device. From GNOME, you
able to easily set it up from the "Wacom" section of GNOME
don't know about other desktop environments off-hand.
I will note, however, that the "xsetwacom" program, which
be used to enable the Wacom device within an Xorg session,
provided by our "xf86-input-wacom" package. You might find
although note that "permanent configuration" will be much
different on a
Guix system than on Arch.
To set it up permanently, it *might* be sufficient to add
the following to your OS configuration, merging it with your
'services' field if needed:
(services (append (list ;; other services go here
(modules (cons xf86-input-wacom
I'm sure this works fine, but at least the X230T's (multi-)touch
screen is fully supported by libinput as well:
So I don't think the Wacom driver (which I don't much like anyway)
3) Fringerprint scanner for authentication.
I'm still stuck on ‘no value specified for service of type
'fprintd'’ (see elsewhere in this thread) but admittedly I gave it
all of 5 seconds before moving on to more important stuff. It's a
fun gimmick though :-)
