Confirmed. For me this bug happens with Radeon cards (using the 'radeon' kernel module).
And also confirmed this is not a duplicate of bug 1723577. I was trying to reproduce bug 1723577 when I encountered this one instead. Can you please provide output from this command?; lspci -k If you happen to have an nvidia card instead then this bug would become invalid. Because the nvidia driver is known to only support Xorg sessions by default. If you have a radeon card though, then this is a new issue which I can confirm. ** This bug is no longer a duplicate of bug 1723577 Artful won't start with Wayland activated (AMD?) ** Changed in: gdm3 (Ubuntu) Status: New => Confirmed ** Changed in: gdm3 (Ubuntu) Status: Confirmed => Incomplete -- 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
