Adding new entries to Grub with alternate kernel parameters

+3
−0

I installed Grub in the normal way and now I have entries in the Grub menu for linux, linux-lts, and the fallback versions of them.

I want to add more entries to this. For example, I want to add linux-lts nomodeset that is the same as linux-lts but without nvidia-drm.modeset=1.

Do I have to manually edit /boot/grub/grub.cfg for this? Or is there a more user friendly way? The syntax of grub.cfg is bad, and I fear my manual changes will get overwritten by grub-mkconfig.

On Ubuntu and Debian (and their derivates) you can use the file /etc/grub.d/40_custom which is intended exactly for this:

Content of /etc/grub.d/40_custom:

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

Just add your menu entries there and they will be added when the grub config is recreated.
