Public bug reported: First observation is that the changelog here:
https://bugs.launchpad.net/ubuntu/+source/gdm3/3.34.1-1ubuntu1 says that the blacklisting of wayland+nvidia was reverted: + Add debian/patches/revert_nvidia_wayland_blacklist.patch: - Don't blacklist nvidia for wayland But this patch isn't in the sources and the blacklist rule is still present. If I disable the udev blacklist rule, wayland on nvidia continues to work as well as it did in 19.04. However, I've been doing a bunch of playing around with hybrid configurations, and there is one situation, where there can be a problem. If you are using nvidia as your primary graphics device, but the Intel one is still visible on the pci bus (not disabled in firmware), then gdm will trigger a kernel oops in the i915 driver if wayland is not disabled. This didn't happen in 19.04 so it's a regression somewhere. ** Affects: gdm3 (Ubuntu) Importance: Undecided Status: New -- 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/1852113 Title: gdm logic for disabling wayland on nvidia is too rigid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1852113/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
