Technically Wayland was never working with the Nvidia driver. Even if you do remember to use nvidia-drm.modeset=1, the problem remains that Ubuntu's mutter builds are missing EGLStreams support. So when the "Ubuntu on Wayland" option was given in 18.04/18.10 it would still only provide software rendering...
Is the problem you see just that the login screen provides no "Ubuntu on Wayland" option any more? ** Package changed: xorg-server (Ubuntu) => mutter (Ubuntu) ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1805561 Title: Wayland not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1805561/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
