Thanks for your reply. I did tick the "proprietary drivers" checkbox during the installation, but for some reason nouveau was enabled afterwards. As for the session-switching gear, it doesn't appear at all when NVidia drivers are enabled.
Now, the problem persists even on a fully up-to-date beta. But at the same time, if there was a widespread issue of such a magnitude (it does prevent booting in normal conditions) affecting NVidia users, other people should be affected... I'm going to assume that I just picked the wrong beta build at the wrong time. If I have some time to spare, I'll check if the issue persists on a fresh install with the latest daily build. Otherwise, I'll just cross fingers and hope that I was simply unlucky and that, when the final release hits next week, everything will be fine on a fresh install. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872123 Title: [20.04] X session fails to start on 440 and kernel 5.4.0-21 (but 5.4.0-18 works) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1872123/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
