Display resolution for console on boot-up

[zmdmw52]

Is there a way to adjust the display resolution of the DOS-like screen
(console) that appears after the appropriate entry in GRUB is
selected? (this is the screen with the scrolling commands).

Earlier it used to be 1440 X 900 (which is the default Monitor
Resolution), but now it is 768 X 680 (after re-install of openSUSE
11.0). I recall there was a line at the bottom stating VGA and then a
combination of alphabets & numbers, but don't remember what it exactly
was.

Tried configuring it from the Boot / GRUB options (there is an entry
for VGA/Monitor Res for Console, down at the bottom), but I do not
know what value to put there.

Start with vga=ask and you will be offerd possible settings.

vga= requires the base-10 number. I think you can use the hex value (0x317)
but I haven't tried it. I just used kalc to convert the hex to base-10. You
can use google too if you want:

Thanks, that helps a lot; will try it out.

You are right, the last line was a hex number (something like 0x317);
which is why I could not remember it. Will try it out both ways (raw 3-
digit no [which, according to the article, should work] & hex number].

BTW, how do I convert XXX (raw no., .... if that is the correct word)
--> hex (hexadecimal) no?...doesn't matter, the Windows Calculator can
do it. Need to add a '0x' before the output displayed from dec -->
hex.

No it doesn't. It accepts hex and decimal mode numbers.

You can, and it works. I used to use 0x317 and 0x314 as the usual modes
when installing but now use their decimal equivalents, 791 or 788, as
it's 2 characters less typing.

Or you can use the page on wikipedia, which gives the mode numbers in
decimal:

Even how interesting this all is, I still think thatthe easiest way is
to do `vga=ask`. You will then see what is possible, try them out and if
you find one, use that in menu.lst (or via YaST) to set it fixed.

Thank you for pointing that out -- it was all of the (GRUB) at the end of
the URL which was not being picked up.

This is a useful reference page.

Thank you once again for providing the link.
