Hello T-G-R!

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

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

1) Buttons on the lid like screen rota=
tion, lock screen etc.

Those buttons act like spec=
ial keys on your keyboard.  The 
following web
page lis=
ts their scancodes, and gives some advice on how to set 
things
up so that the buttons behave as expected:

  http=
s://www.thinkwiki.org/wiki/Tablet_Hardware_Buttons

=

The page recommends using xbindkeys, which is provided by the 
Guix
"xbindkeys" package, but depending on which desktop envir=
onment 
you use,
there might be a more straightforward =
way to arrange for a 
script to be
run when you press a=
 key.

Exactly.  I used =E2=80=98xev=E2=80=99 (avai=
lable in Guix) to get the keycode for 
what I presume is the scre=
en rotation button(? there are two, the 
pictograms are pretty va=
gue, 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 simple (well=E2=80=A6) 
shell script that uses xrandr to query the current screen 
orien=
tation and cycle to the next one (I use left/right/normal, 
never=
 inverted):

  xrandr --output LVDS-foo --rotate no=
rmal|left|right|...

The only problem is that press=
ing the button once produces a 
deluge of press events.  Luckily =
the number is usually constant 
(so it's not just a =E2=80=98repe=
at=E2=80=99 without a =E2=80=98delay=E2=80=99) making the end 
re=
sult predictable.  In practice it means I'm cycling backwards 
th=
rough 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?

Haha no.

2) Input using stylus pen.
=


The touch screen is apparently a Wacom device.  From GN=
OME, you 
might be
able to easily set it up from the "W=
acom" section of GNOME 
settings.  I
don't know about o=
ther desktop environments off-hand.

I will note, h=
owever, that the "xsetwacom" program, which 
apparently 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 
<https://wiki.ar=
chlinux.org/index.php/Wacom_tablet>,
although note that "p=
ermanent configuration" will be much 
different on a
Gu=
ix system than on Arch.

To set it up permanently, =
it *might* be sufficient to add 
something like
the fol=
lowing to your OS configuration, merging it with your 
existing
'services' field if needed:

    (services=
 (append (list ;; other services go here
                        =
    (set-xorg-configuration
                             (xorg-co=
nfiguration
                              (modules (cons xf86-inp=
ut-wacom
                                             %default-xo=
rg-modules)))))
                      %desktop-services))

I'm sure this works fine, but at least the X230T's (multi=
-)touch 
screen is fully supported by libinput as well:

  Section \"InputClass\"
   Identifier \"Touchscr=
eens\"
   MatchIsTouchscreen \"on\"
   MatchDevicePath =
\"/dev/input/event*\"
   Driver \"libinput\"
  EndSecti=
on

So I don't think the Wacom driver (which 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 ty=
pe 
'fprintd'=E2=80=99 (see elsewhere in this thread) but admitte=
dly I gave it 
all of 5 seconds before moving on to more importan=
t stuff.  It's a 
fun gimmick though :-)

Kind regards,

T G-R
