Changes To Grub Customizer LM 21.1 Cinnamon <Solved>

Also see my Post in my tread on brightening grub

If you add the line in /etc/default/grub - some distros prefer ,png over .jpg/.jpeg so I usually just use a picture in /boot/grub.

Also, you can have more than one picture in /boot/grub - it will take the first one alphabetically.

Tried both and unfortunately it doesn't work.
I still have a all black background with white letters.
Hi Alexzee can you give us a look at your /etc/default/grub file?

Alexzee ... just checking: did you convert the Ocean.jpeg to Ocean.png using the convert command in post #37? Does the command:
identify Ocean.png
confirm that the pic is 8-bit and RGB format?

You could also try commenting out the config: GRUB_GFXMODE=1920x1080, in your grub file to let grub decide it's own mode. Dunno how relevant that it, but in my case, it's commented out and works.

Post #45 helped!
I edited the /etc/default/grub file and got rid of the quotation marks before the forward slash before boot and after the png and updated grub.
This is what I changed it too and rebooted.

I now have the picture when the Grub Menu appears!
Glad it's finally working for you , enjoy! :)
