Linux Mint 20.2 will not boot with Quadro card installed. SOLVED

[SMG]

SMG,

Thank you SO MUCH for your time, knowledge, and patience. The machine and Nvidia are working again. I now have to reinstall the drivers, so that my 2 monitor setup will kick in again, but aside from that everything is back to the way it was.

Was it a bad cable? Or just a loose connection?

Please go to your first post in this topic, click the pencil icon, and add [SOLVED] to the beginning of the title so others know you are no longer seeking help on this issue.

One more, completely unrelated, question: after one of the updates the speed of my network appears to have been cut in half. When I compare the network connection from this machine vs. the connection from a Windows machine - each with a 1 Gig port and connecting to the same port on the switch - the Win machine achieves twice the speed!? Any idea why?

Network: Device-1: Broadcom and subsidiaries NetXtreme BCM5723 Gigabit Ethernet PCIe
vendor: Hewlett-Packard NC107i Server driver: tg3 v: 3.137 port: 2000 bus ID: 1e:00.0
chip ID: 14e4:165b
IF: ens1 state: up speed: 1000 Mbps duplex: full mac: <filter>

Sounds like an issue with an update. Usual methodology is to revert back to a working snapshot and then test the updates individually (or in small groups if there were a lot of updates) to determine which one might be the one causing the problem. I don't help much with networking speed issues so nothing comes to mind for me. I suggest creating a new topic for that in the Networking section of the forum if you are not able to find a cause.

Thanks again.

I did mark the thread as solved.
