After re-installing f33 following a disk crash, I was having problems that I believe were caused by nouveau trying to run on my gpgpu nvidia 2080 ti. I don't need or want a display manager running on it. How can I tell if wayland and/or X is configured to run on that card, and how can I disable it for that card? I also have a built-in vga that runs a display.
Thanks, Neal
I'm not sure I have a 100% solution for you but you could start with blacklisting the nouveau driver...
/etc/default/grub: GRUB_CMDLINE_LINUX="<current stuff> rd.driver.blacklist=nouveau modprobe.blacklist=nouveau"
(assuming UEFI) # grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
HTH!

Also blacklist the proprietary Nvidia driver if it's installed (or uninstall it of course).
I was about to make the same suggestion since I do this myself in order to run GPU pass-through to a Windows VM guest, however the side-effect is that the GPU is no longer accessible from Linux, which may not be what the OP wanted.

If I understand correctly, I will need the nvidia driver installed to use the gpgpu for M/L. I don't want/need to run a display on it (wayland or X11). Thanks, Neal

Why not set the default.target to multi-user.target instead of graphical.target?
Maybe not a bad idea. Sometimes I might want a graphical interface on the built-in vga.

Well, if you want the graphical login, then you need to run a graphical interface. If you want to run it on a different card, set up X11 to talk just to that video card. Something like this if the internal GPU is the Intel i915 (which I have in my servers).
