Adding kernel boot param

As this read suggests, I have

  • Syslinux #BIOS
    linux /boot/vmlinuz-linux ... params
  • systemd-boot #UEFI
    inird /boot/intel-ucode.img /boot/initframfs-linux.img

Question 1: do I have both on this new Dell Laptop set to UEFI?

Question 2: param fbcon=font:TER16x32 seems to work only with Syslinux #BIOS.

Question 3:
neither (primarily)
is found to make a boot param persist. (/loader/ is /grub/ here).

Any advices? Thanks.

When you add a kernel parameter to the default grub command line you have to update grub also to make it permanent.

sudo grub-mkconfig -o /boot/grub/grub.cfg

Tell us your problem (if you have any), not what you believe is the problem solution. It’s a basic xyproblem issue.
All the above cannot make technical sense together.

Give your system info.
Post relevant files’ contents.

(U)EFI has its own frame buffer.

You are right. The problem is:

  • increase the font size for on Linux console (tty)

Steps to reproduce:

  1. sudo systemctl set-default and reboot
  2. trap grub to add a kernel param by pressing “e”
  3. work out where to add fbcon=font:TER16x32
  4. after a successful boot, make that font size persist on next boot

The BIOS vs UEFI question may be secondary.

So if you are using Grub as bootloader then please see:

for how to add parameters to the kernel’s boot options.


That works like a charm :slightly_smiling_face:
