Hi,
With this patch I finally have a readable GRUB menu. I am not sure
about the name and semantics of `resolution': Better to use `gfxmode',
and/or use a list of strings '("1024x768x32" "auto"), ... WDYT?
Greetings,
janneke

Hi Jan,
This seems like a sensible change, and is something other distributions
seem to implement in their own manner, as well. I am in favor of this
change, and will test it ASAP.

Yes please, on both counts. Grub-theme should expose the GRUB
variable, not a lossy abstraction.

Okay, I think I just wished the GRUB name would be more meaningful for
casual users (such as myself). I'm terrible with TLAwords, and very
happy I found and fixed this ;-)

Especially with HiDPI, the word "resolution" is ambiguous.
Also, gfxmode values are not standardized (f.e. u-boot would not know what
to do with them), so using a non-grub-specific key doesn't bring us anything.
I much prefer lists instead of one string. But grub apparently has "," and
";" as separators--presumably with the same meaning?
It also has the special value "keep" as possible first item.
In view of this complication it's maybe better not to use lists.

That's another good argument; thank you for chiming in! I think we all
agree now. I sent an updated patch using `gfxmode' in another mail.

Yes, that was also Tobias' wish, so we now have it as a list too.

Hmm, yes that's why I had some doubts too. After Tobias' comment I now
chose to use a list, and the example now says
(gfxmode '("1024x786x32" "auto"))
I hope that people can imagine prepending "keep"?
Greetings,
janneke

I found this test to also show the failure.

It turns out that this test creates a grub bootsloader with #f for

Attached is a new version of the patch, that is robust against this;
