Hello,
In GNOME the touchpad settings don't show up and the 'Tap to Click'
function does not work on my laptop.
I found the following tickets regarding the problem:
1) https://bugzilla.gnome.org/show_bug.cgi?id=747956
2) https://lists.debian.org/debian-devel/2016/07/msg00266.html
It looks like a conflict between xf86-input-synaptics and
xf86-input-libinput.
Workaround,
I've removed xf86-input-synaptics from 'xorg' service and later I
reconfigure:
'guix system -L /home/jin/guix/ reconfigure os-config-gnome.scm'
Works for now!, any idea how we can establish the order in which xorg
service loads the driver?
