On a fresh Ubuntu 20.04 install I ran into this same issue. Tap to click works fine on the desktop, but it does not work on the login screen. The inconsistent behaviour can be very confusing.
Won't it be best to make the behaviour on the login screen and on the desktop match? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1711538 Title: Tap-to-click does not work on the GDM login screen To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1711538/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
