Adding a GRUB2 background image and custom font

rated 0 times [ 3] [ 0] / answers: 1 / hits: 20714 / 2 Years ago, tue, september 13, 2022, 1:32:57

I am trying to use grub-customizer to add a custom background image and use the Ubuntu Condensed font. The preview looks fine:

enter image description here

But when I actually boot up, I get a messed-up configuration. The text is messed-up, with "unknown character" symbols appearing for the box around the boot menu options (because apparently only the default grub font has these special characters?). However, the boot options are in the Ubuntu font. There is only a black screen as the background.

I'm trying to use a 1366x768 (same as my screen res) .png as the background image. This should be compatible, right? What can I do to get a background image working?

Sorry for the wait:

Info about changing GRUB font to Ubuntu-Mono that I should have found earlier:

In this question, OP tried to change font without results. Problem appears to be a bug with ascending order glyphs as per this answer.

So basically I can't use anything from the Ubuntu Font Family for my GRUB font (sad but true) until the bug is fixed.

Info about background image:

If no option is specified in /etc/default/grub, GRUB will use the first found image in /boot/grub. The image must in RGB colorspace and, if a JPEG, 8-bit. GRUB will automatically detect the screen resolution, no configuration needed, and stretch/shrink the image if necessary (from thegeekstuff.com).

So to sum up, all that was needed was for me to just go with the default font (no way around it) and edit my image in GIMP to fit the parameters.
