Thanks. That's very interesting. I've only ever seen Ubuntu get stuck on that purple screen when there was a graphics driver bug (it was the VMware driver last time - bug 1832138). So that makes me think there's a problem with the nvidia-340 driver, OR it could mean some fallback codepath in mutter to support old drivers is buggy.
The bad news is I don't think I can test the nvidia-340 driver anymore because the only Nvidia cards new enough to support my monitors are too new for that driver :S ** Summary changed: - Ubuntu 20.04 not booting with NVidia proprietary drivers (follow-up from bug 1889377) + Booting Ubuntu with Nvidia-340 gets stuck on a plain purple screen ** Changed in: nvidia-graphics-drivers-340 (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889541 Title: Booting Ubuntu with Nvidia-340 gets stuck on a plain purple screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/+bug/1889541/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
