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 Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1711538 Title: Tap-to-click does not work on the GDM login screen Status in gnome-control-center: New Status in GNOME Settings Daemon: Won't Fix Status in gdm3 package in Ubuntu: Triaged Status in gnome-control-center package in Ubuntu: Triaged Bug description: Tap-to-click does not work in GDM login ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: gdm3 3.25.90.1-0ubuntu1 ProcVersionSignature: Ubuntu 4.12.0-11.12-generic 4.12.5 Uname: Linux 4.12.0-11-generic x86_64 ApportVersion: 2.20.6-0ubuntu5 Architecture: amd64 CurrentDesktop: GNOME Date: Fri Aug 18 16:16:56 2017 InstallationDate: Installed on 2017-05-04 (105 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Alpha amd64 (20170503) SourcePackage: gdm3 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1711538/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
