I discovered recently that one way to make the Wayland login options vanish is to have any bug in the mutter eglnative backend that triggers an assertion. gnome-shell doesn't treat this as fatal, but it does remove Wayland options from the list of login sessions in that case.
So this assertion from your log might be relevant: loka 08 10:50:57 username-System-Product-Name gnome-shell[2848]: setup_framebuffers: assertion 'width > 0' failed Or it might be one of the other gnome-shell assertions in your log. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722041 Title: No Ubuntu wayland option when swiching user with automatic login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1722041/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
