It did not work :-(

I my regular account a grep for 'tap-to-click' in ~/.conf does find a 
match in ~/.conf/dconf/user. So setting this option through dconf or 
gsettings is probably the right basic idea.

On Debian the gdm3 user is called 'Debian-gdm' and its shell is 
'/bin/false'. So I su-ed to root and ran the following command:

sudo -u Debian-gdm gsettings set org.gnome.desktop.peripherals.touchpad tap-to-click true

But I got the following error:

(process:26300): dconf-WARNING **: failed to commit changes to dconf: 
Error spawning command line 'dbus-launch 
--autolaunch=f856067f8571c63f807f753100000009 --binary-syntax 
--close-stderr': Child process exited with code 1

I'm not sure where to go from there. ~/.conf/dconf/user is a binary file 
so editing it directly is out.
