I am trying to boot a Linux system (Debian 11) with an NVIDIA GPU; I need to avoid loading the nouveau driver, which I can do if I include some options on the linux command line (in grub.cfg):

terminal_input console
terminal_output console
set gfxmode=text
set timeout=5

menuentry 'Debian 11' {
  linux /debian11/boot/vmlinuz-5.10.0-22-amd64 console=tty0 ip=dhcp root=/dev/nfs ro nfsroot=192.168.50.111:/image/debian11,vers=3,nolock panic=60 ipv6.disable=1 rootwait vga=normal nofb nomodeset video=vesafb:off
  initrd /debian11/boot/initrd.img-5.10.0-22-amd64
}

The reason for doing this is that I need to load NVIDIA's proprietary modules, and it works OK, as far as it goes. The unfortunate consequence of this is that I no longer have the VTYs available - not a huge problem, since this is for a server that is mostly accessed via ssh, but sometimes it is necessary to look at the text console, so I'd like to have it back - but without loading the nouveau module. This used to be perfectly easy in the past, but it seems the kernel insists on loading a framebuffer device instead of just printing text.

Is there a way to fix this?

    Why aren't you using simpledrm/simpledrmdrmfb? It works just fine with NVIDIA.

  • @ArtemS.Tashkinov I was not aware there was such a thing :-) I'll check it out. Does it require rebuilding the kernel?

  • Dunno, aren't you running your distro kernel?

    I understand nomodeset but who or what added vga=normal nofb video=vesafb:off? Those don't look appropriate or warranted at all. Try without them.
