Solved! I went to BIOS and switched the Video card setting from Hybrid to Discrete. Now gdm3 offered the wayland option (or, rather, both "Ubuntu" and "Ubuntu on Xorg"). I now run Wayland as confirmed by env|grep wayland: XDG_SESSION_TYPE=wayland I believe that nouveau driver is actually being used, so I need to look into the possibility to force Intel, to achieve better support. Anyways, it seems that Hybrid mode won't pass gdm3 validation routines and it disables Wayland support; switching to Discrete solves the issue. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1724583 Title: gdm3 doesn't list wayland-based sessions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1724583/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
