Two questions: 1) is there some random "magic" on the kernel command line (something needed specificly for the old nvidia card)? If so, that that "magic" is likely breaking things with the nvidia card "missing".
2) is the "server" trying to come up with a graphical login? It is almost always a bad idea for a server to every come up with a graphical login. I consider having any machine coming up in a graphical login is going to be problematical at some point. And anytime you do some sort of hardware change is good time for problems. Before you swap the new video card into the "server", change its target server to NOT be the graphical login, *before* you shut it down. And also before shutting it down clean any extra stuff on the command like and remove the quiet and splash options off of the kernel command line (if any). This will make the boot up "verbose". If it is going to crash or hang, you will know what was the last thing the kernel had to say. At Wed, 22 Jul 2026 09:34:01 -0600 "D. R.
