The video card in question has died... The machine wouldn't boot at all with the video card in the machine. So I think the bug report should be retired, not so much resolved as unresolvable. I can't collect any more data on the symptoms and I can't swear the problem wasn't an early indication of hardware failure.
Thanks to all who had suggestions. I did manage to try the NVidia 430 driver before it died. It didn't work, but it had different symptoms. X wouldn't come up, but I could ctrl-alt-f1 to get to a command line and switch back to nouveau, instead of having to boot to command line. It was replaced with an even older card (GeForce 9500 GT), which also didn't work with the NVidia drivers, and had an unreliable fan, so I had to put an extra fan in the case until I got around to applying a crowbar to the notoriously tight wallet and get a brand new Radeon RX580. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-390 in Ubuntu. https://bugs.launchpad.net/bugs/1846899 Title: X won't start at boot with either nvidia driver on GeForce GT 730 (bionic) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1846899/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
