Hello, have success install fedora server 39 on server with CPU 2680v4 which is dont have graphic core. I installed external gpu for load server and when i remove gpu - server was loaded success (i see on postcard motherboard that os is success boot) but i dont have a ping and cant connect to server through ssh client.
I try to modify grub from this:
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=“$(sed ‘s, release .*$,g’ /etc/system-release)”
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT=“console”
GRUB_CMDLINE_LINUX=“rd.lvm.lv=fedora/root rhgb quiet”
GRUB_DISABLE_RECOVERY=“true”
GRUB_ENABLE_BLSCFG=true

to this:
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=“$(sed ‘s, release .*$,g’ /etc/system-release)”
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT=“console”
GRUB_CMDLINE_LINUX=“rd.lvm.lv=fedora/root”
GRUB_DISABLE_RECOVERY=“true”
GRUB_ENABLE_BLSCFG=true

after that i make:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
sudo reboot

but still cant ping server without videocard

Don’t do this.

If you have already done this you will need to recover or manually repeat the same command every time a kernel is updated.
Recovery involves 2 steps.
sudo rm /boot/efi/EFI/fedora/grub.cfg /boot/grub2/grub.cfg
followed by
sudo dnf reinstall grub2-common which should recreate both those files properly.

still nothing. i reinstalled grub. Again make changes and update only 1:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
without video card still cant ping and ssh access, BUT i seen error message when i try boot without gpu, maybe this is the reason:
