Hello, Guix Help! I am not able to use tap on my touchpad. Scroll is working, mouse motion is working, left and right buttons are working, but tap and double click are not working on my touchpad.

As described in the Internet need to use /etc/X11/xorg.conf.d/90-synaptics.conf. 
But GuixSD has own filesystem structure, so there is no /etc/X11.

Here it is configuration file xorg.scm: https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/xorg.scm?id=v0.15.0-2564-g38a2f5eaf#n2564 <https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/xorg.scm?id=v0.15.0-2564-g38a2f5eaf#n2564>

I assume xorg configurations ought to be done. Please, how to write my config.scm?

Hi!

Consult the manual, "(guix) X Window".  There is an example near the end:

--8<---------------cut here---------------start------------->8---
          (define bepo-evdev
            "Section \"InputClass\"
                  Identifier \"evdev keyboard catchall\"
                  Driver \"evdev\"
                  MatchIsKeyboard \"on\"
                  Option \"xkb_layout\" \"fr\"
                  Option \"xkb_variant\" \"bepo\"
          EndSection")

          (operating-system
            ...
            (services
              (modify-services %desktop-services
                (slim-service-type config =>
                  (slim-configuration
                    (inherit config)
                    (startx (xorg-start-command
                             #:configuration-file
                             (xorg-configuration-file
                               #:extra-config
                               (list bepo-evdev)))))))))
--8<---------------cut here---------------end--------------->8---

The above example only details keyboard configuration.  For your trackpad, have
a look at libinput's manpage.
Also https://wiki.archlinux.org/index.php/Libinput may give you a good coverage
of the topic.

I've been having the same problem on my Think Penguin laptop, and since
seeing this email, I've tried modifying my config.scm unsuccessfully.
I've run the reconfigure command and rebooted. Here is my services
field:

---BEGIN---
  (services
   (cons* (gnome-desktop-service) (console-keymap-service "dvorak")
	  (extra-special-file "/usr/bin/env" (file-append coreutils
"/bin/env")) (modify-services %desktop-services
			   (slim-service-type config =>
					      (slim-configuration
					       (inherit config)
					       (startx
						(xorg-start-command
						 #:configuration-file
						 (xorg-configuration-file
						  #:extra-config
						  '(
"Section \"InputClass\"
        Identifier \"keyboard-all\"
        Option \"XkbLayout\" \"dvorak\"
        MatchIsKeyboard \"on\"
EndSection
Section \"InputClass\"
	Identifier \"touchpad-all\"
	MatchIsTouchpad \"on\"
	Option \"DisableWhileTyping\" \"on\"
	Option \"Tapping\" \"on\"
EndSection"
))))))
			   (guix-service-type config =>
					      (guix-configuration
					       (inherit config)
					       (substitute-urls
						(list
						 "https://berlin.guixsd.org"
						 "https://mirror.hydra.gnu.org"
						 "https://hydra.gnu.org")))))))
---END---

Neither DisableWhileTyping nor Tapping has any effect. I also set the
corresponding settings in Gnome Tweaks > Keyboard & Mouse > Touchpad.
If I need a Driver field or some specific Identifier, I haven't been
able to find a way to determine the correct info for those fields.

Here's what I use:

  Section \"InputClass\"
   Identifier \"Touchpads\"
   Driver \"libinput\"
   MatchDevicePath \"/dev/input/event*\"
   MatchIsTouchpad \"on\"

   Option \"DisableWhileTyping\" \"on\"
   Option \"MiddleEmulation\" \"on\"
   Option \"ClickMethod\" \"clickfinger\"
   Option \"Tapping\" \"on\"
   Option \"TappingButtonMap\" \"lrm\"
   Option \"TappingDrag\" \"on\"
   Option \"ScrollMethod\" \"twofinger\"
   Option \"NaturalScrolling\" \"true\"
  EndSection

xinput(1) calls it an 'ETPS/2 Elantech Touchpad'.

Kind regards,

Thanks, but I still can't get it to work. This is my current config:

Section \"InputClass\"
	Identifier \"Touchpads\"
	Driver \"libinput\"
	MatchDevicePath \"/dev/input/event*\"
	MatchIsTouchpad \"on\"
	Option \"DisableWhileTyping\" \"on\"
	Option \"Tapping\" \"on\"
EndSection

I've found from xinput that it's a 'SynPS/2 Synaptics TouchPad' at
device node /dev/input/event6. I can't find a way to confirm the driver
name.
