@Daniel, Now this issue in my side is not related to https://gitlab.gnome.org/GNOME/mutter/merge_requests/160, I've updated the latest mutter(3.28.3-2~ubuntu18.04.1), this issue is still exist, and I tried to make it with small patch, but I'm failed.
So could we used the patch in comment #7? Now I just found the gdm3 was updated to 3.28.3-0ubuntu18.04.1, the previous patch also need be changed. And I found the gdm-disable-wayland binary is missed, so I report an issue for it. https://gitlab.gnome.org/GNOME/gdm/issues/412 -- 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/1780076 Title: 18.04 login screen is skewed/distorted (incorrect stride) when using hibmc_drm graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1780076/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
