You appear to be using the 'oibaf' PPA which is not supported and is known to cause bugs like this. Please uninstall it using 'ppa-purge', reboot, and then open new bugs about any new issues you find. ** Changed in: gdm3 (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944581 Title: Session preference not respected; Wayland session started despite Xorg being selected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1944581/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
