Missing display resolutions in "boot options" tab

Unfortunately, not at this time. Please see http://ubuntuforums.org/showpost.php?p=2027889 for more info.

If it can be useful to you, I've set my grub configuration manually
using values obtained with this command:

kamal@rohan:~$ sudo hwinfo --framebuffer | grep 1920
  Mode 0x037c: 1920x1200 (+1920), 8 bits
  Mode 0x037d: 1920x1200 (+7680), 24 bits

Then I converted that value to decimal:

kamal@rohan:~$ printf '%d\n' 0x037d
893

And so I set vga=893 and it's working. (I have to admit that usplash
seems a bit "stretched", but it's better than nothing).

However something is strange because the table I get from hwinfo
doesn't match exactly the one here:
http://ubuntuforums.org/showthread.php?p=1541970

For example hwinfo gives 0x034a for 1600x1200@24 instead of 0x31f. But
for 1024x768@24 it gives the same: 0x318.

However thank you for your help.

Thanks for the tip. I might hack something together to use the output of hwinfo in the future.

This might not be as straight-forward as I thought, I noticed hwinfo reports resolutions too large for my monitor using my new graphics card.
If that is solved in hwinfo, I will still need a good way to extract the info from the output. Screenscraping is a bit unreliable.
Hmm, this might be tricky to solve.

Thanks for the hwinfo/printf tip. My widescreen LCD monitor doesn't even support 1600x1200 so setting that in SUM causes grub to fault when loading my kernel (although allowing me to continue booting with a safe resolution after a delay).

hwinfo --monitor isn't accurate, neither is read-edid/get-edid/parse-edid on my setup (nvidia propriety drivers)
I also tried xrandr which fails with nvidia twinview.
xresprobe/ddcprobe, discover, cvt, gtf and glxinfo are all useless.

I can't imagine another way of detecting max monitor resolution. Offering all resolutions the graphics card has available is a start, at least it would save someone like me finding this thread and posting this.

Some modes:

0x360 1280x800x8
0x361 1280x800x32
0x368 1680x1050x8
0x369 1680x1050x32

(I got it from vga=ask)

Is this still an issue for you? What Ubuntu version do you use? Thank you for telling us!
