Missing display resolutions in "boot options" tab

[Kamal]

Binary package hint: startupmanager

In the first tab of the program, "Boot options", the maximum resolution I can see is 1600x1200, and in general it's missing all "wide" resolutions like 1440x900, 1680x1050 etc...
My display is currently working at 1920x1200, is it possible to add resolutions up to that one at least?
I'm using Ubuntu 7.10 Gutsy Gibbon for AMD64.

Thank you.

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:

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!
