I've just installed an Fedora 23 system which I purposely did not include X-windows as the machine will always be accessed remotely.
My problem is I want to disable or force a basic graphics mode upon boot-up, currently when the system boots is reaches a specific point and the display changes from 80x24 to some higher resolution, how do I stop this behavior and leave a very basic display setting? By doing so I hope to be able to move the disks to different hardware easily without having to worry about graphics adapters.
Thanks, Jeff
You can add nomodeset to the kernel argument and that will give you what
you are looking for, let me know if that works
Looks like it does exactly what I wanted, I added it to /etc/default/grub file in the line "GRUB_CMDLINE_LINUX" and removed rhgb and quiet while I was at it followed by a grub2-mkconfig....
Thanks, Jeff

While the default for the past few Fedora releases is to not necessarily be completely hardware generic (to save bootup time and disk space), I don't think this appliest to graphics drivers -- if you move your disk, the right new driver will automatically be selected (including a very basic one if that's not available).
To get a generic image, install the dracut-config-generic image, and rerun dracut (or do a kernel update, which will include that). Or, if you've forgotten, the rescue image is _always_ hardware agnostic (including all drivers).

installing the dracut-config-generic via dnf is easy enough, but do I need to tell dracut which driver(s) to exclude or do I simply do a "dracut --force" to get it to rebuild? I guess the other option would be to do something like "dracut generic-kernel.img 4.3.3-300.fc23.x86_64" and then add that to the grub boot menu.
