This is a grub, not a Whonix ™ feature. Therefore Free Support Principle applies.
Permanent Configuration Changes[edit]
1. Learn.
- See folder
/etc/default/grub.d. - See file
/etc/default/grub.d/40_kernel_hardening.cfg. - Just look around.
2. Create a new configuration file.
Open file /etc/default/grub.d/50_user.cfg in an editor with root rights.

This box uses sudoedit for better security [archive]. This is an example and other tools could also achieve the same goal. If this example does not work for you or if you are not using Whonix, please refer to this link.
sudoedit /etc/default/grub.d/50_user.cfg
3. Paste.
Notes:
- The following example uses kernel parameter
nomodeset. - You need to replace
nomodesetwith the actual kernel parameter you want to add. - Don't remove the leading text.
- Visual elaboration: Marked with underline
GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX nomodeset". Do not remove underlined part.
- Visual elaboration: Marked with underline

nomodesetwith the actual kernel parameter you want to add.

The process is complete.
