At first I thought this might be boot failure bug 1872159. To test that, just try removing the 'splash' kernel parameter. But maybe that's not the problem...
I can see another problem; that your Nvidia driver is not only an unsupported version, but it's also not installed properly. This seems to be resulting in the open source driver running the Nvidia GPU when it shouldn't. So this bug is invalid for now. Please uninstall the Nvidia driver you have and use the 'Additional Drivers' app to install the supported version 440. If you encounter any problems after that then please open new bugs for them. Also, if you find any evidence of crashes in /var/crash then please use the 'ubuntu-bug' command to turn those into new bugs. ** Changed in: xorg (Ubuntu) Status: New => Invalid ** Summary changed: - Xorg crash + [nvidia] Xorg crash ** Tags added: nvidia -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891313 Title: [nvidia] Xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1891313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
