Hello T-G-R!

In co=

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-module= s" and "(service fprintd-service-type)" in "services"; of system config.

Regards,

I just got an X230T so I'm very interested in g=
etting the same 
things working.

1) Butt=
ons on the lid like screen rotation, lock screen etc.

<= pre>Those buttons act like special keys on your keyboard. The

page lists their scancodes, and gives some advice on=
 how to set 
things
up so that the buttons behave as ex=
pected:

  https://www.thinkwiki.org/wiki/Tablet_Hardware_B=
uttons

The page recommends using xbindkeys, wh=
ich is provided by the 
Guix
"xbindkeys" package, but d=
epending on which desktop environment 
you use,
there m=
ight be a more straightforward way to arrange for a 
script to be=

run when you press a key.

Exactly.  I u=
sed =E2=80=98xev=E2=80=99 (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 
  /home/nckx/.config/i3/rotate-screen.sh

to my ~/.config/i3/config.  rotate-screen.sh is a si=
mple (well=E2=80=A6) 
shell script that uses xrandr to query the =
current screen 
orientation and cycle to the next one (I use left=
/right/normal, 
never inverted):

  xrand=
r --output LVDS-foo --rotate normal|left|right|...

The only problem is that pressing the button once produces a 
de=
luge of press events.  Luckily the number is usually constant 
(s=
o it's not just a =E2=80=98repeat=E2=80=99 without a =E2=80=98delay=E2=80=
=99) 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 <=
/pre>
in tablet mode anyway.  Will this finally push me to GNOME?
=


Haha no.

2) Input using stylus=
 pen.

The touch screen is apparently a Wacom devic=
e.  From GNOME, you 
might be
able to easily set it up =
from the "Wacom" section of GNOME 
settings.  I
don't k=
now about other desktop environments off-hand.

I w=
ill note, however, that the "xsetwacom" program, which 
apparentl=
y can
be used to enable the Wacom device within an Xorg session, =

should be
provided by our "xf86-input-wacom" package. =
 You might find 
other useful
information on 
<http=
s://wiki.archlinux.org/index.php/Wacom_tablet>,
although n=
ote that "permanent configuration" will be much 
different on a
Guix system than on Arch.

To set it up pe=
rmanently, it *might* be sufficient to add 
something like
<=
pre>the following to your OS configuration, merging it with your 
existing
'services' field if needed:

  =
  (services (append (list ;; other services go here
             =
               (set-xorg-configuration
                          =
   (xorg-configuration
                              (modules (co=
ns xf86-input-wacom
                                             =
%default-xorg-modules)))))
                      %desktop-service=
s))

I'm sure this works fine, but at least the X23=
0T's (multi-)touch 
screen is fully supported by libinput as well=
:

  Section \"InputClass\"
   Identifier=
 \"Touchscreens\"
   MatchIsTouchscreen \"on\"
   Match=
DevicePath \"/dev/input/event*\"
   Driver \"libinput\"
  EndSection

So I don't think the Wacom driver (w=
hich I don't much like anyway) 
is mandatory.

3) Fringerprint scanner for authentication.

=
I'm still stuck on =E2=80=98no value specified for service of type 
'fprintd'=E2=80=99 (see elsewhere in this thread) but admittedly I gave =
it 
all of 5 seconds before moving on to more important stuff.  I=
t's a 
fun gimmick though :-)
