Conditional themes?

[Dr. Tilmann Bubeck]

Hello GRUB,

are there plans to make theming conditional, depending on screen  
resolution? Today you have one theme, which is used for all screen  
resolutions from 320x200 up to 1600x800. When using "gfxmode=auto" you do  
not really know, which resolution you get. The theme may look ugly or may  
be completly unusable (see  
https://bugzilla.redhat.com/show_bug.cgi?id=850783).

I could think of some application logic in grub.cfg, e.g.

if [ "${gfxwidth}" -lt 800 ]; then
  theme=${root}/grub2/themes/small
else
  theme=${root}/grub2/themes/large
fi

What do you think about that?

An even more general idea would be to implement a shellish backticks  
operator $() and extend some commands to print out information (here  
"videoinfo"), like:

width=$(videoinfo --show-width)
if [ "${width}" -lt 800 ]; then
  theme=${root}/grub2/themes/small
else
  theme=${root}/grub2/themes/large
fi

Any comments?

Kind regards,
 Tilmann
