I recently lost tap-to-click ability at the login screen (gdm). I originally enabled it in 17.10 and it survived into 18.04 until a few days ago. So I'm not sure what happened.
I followed instructions here by doing:
sudo -u gdm gsettings set org.gnome.desktop.peripherals.touchpad tap-to-click true
But I'm getting this error message:
(process:26095): dconf-CRITICAL **: 17:43:24.120: unable to create
directory '/home/user/.cache/dconf': Permission denied. dconf will
not work properly.(process:26095): dconf-WARNING **: 17:43:24.120: failed to commit
changes to dconf: Could not connect: Connection refused
And when I run to try and fix:
sudo -u gdm dbus-launch gsettings set org.gnome.desktop.peripherals.touchpad tap-to-click true
I get this:
(process:26477): dconf-WARNING **: 17:52:56.774: failed to commit
changes to dconf:
GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._g_2dfile_2derror_2dquark.Code2:
Cannot open dconf database: Failed to open file
“/home/user/.config/dconf/user”: Permission denied
I decided to try deleting ~/.cache/dconf and tried again to no avail.
Can anyone help?
Thanks.
Edited to add more info.

Try this: Enable ‘Tap to click’ in Ubuntu. It worked for me.
