I've enabled tap-to-click in Gnome but it doesn't work on GDM.
I tried running
dconf-editor as root to modify the setting but to no avail.
I also tried running
sudo -u gdm gsettings set org.gnome.desktop.peripherals.touchpad tap-to-click true but I get the following error
(process:16560): dconf-WARNING **: failed to commit changes to dconf: Error spawning command line 'dbus-launch --autolaunch=long-number-here --binary-syntax --close-stderr': Child process exited with code 1
How do I enable tap-to-click on GDM?
