Widescreen VGA modes

[Ryan McCoskrie]

This is a little issue that has been bothering me for a while. Does anyone
know about /widescreen/ vga modes? I'm trying to set the screen resolution
in grub2 on a pair of monitors. The first (my desktop) has a resolution of
1600x900 (not mentioned by vbeinfo) and the other (my netbook) has a
resolution of 1024x600.

Could someone tell me if there are any (even theoretically) correct vga modes
for these? It's not a major issue, just a niggling problem.

The Linux video mode number is simply the VESA number plus 512. Above
1280x1024 are not covered by the standard, and every graphics card
manufacturer uses its own codes.

You can try:
hwinfo --framebuffer to find out what got passed to the kernel
... but that's not really what you are asking. Afraid you just have to
ask the manufacturer. Anything else is a guess.

... from above - there are no standard modes, but there will be a
"correct" one set by the manufacturer.
