Syslinux - May 2010 - How to set a portrait mode screen using i915 driver?

I am trying to setup a portrait mode screen. I can see that in 3.85,
there is an enhancement which allows arbitrary resolutions
(http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=commitdiff;h=5d4ade0221c2387345d0a82422866bb8b937cb09).
Can I use this new feature to achieve setting the portrait mode. What
is the syntax in the config file to set it? Also, is there any other
vesa driver dependencies?

Thanks,
SR

If with portrait mode you mean a screen that scans vertically rather
than horizontally (as when taking an ordinary screen and rotating it),
no, that is not supported in the current version.

The arbitrary resolution can, however, support horizontally scanned
portrait mode, e.g. "MENU RESOLUTION 480 640".

Yes, I only need horizontally scanned
portrait mode. Somehow "MENU RESOLUTION" does not work for me. Below
is my
isolinux.cfg file. Anything wrong with it?

*MENU RESOLUTION 480 640*

The arbitrary resolution can, however, support horizontally scanned
portrait mode, e.g. "MENU RESOLUTION 480 640".

-hpa

Looks like "MENU RESOLUTION" only changes the screen size/resolution
for the
menu, but not the graphic image loaded afterward. How can I make the graphic
image loaded to be in portrait mode?

Thanks,
S.R.

You have to size the image properly.

Sorry if I did not state my question properly. By referring to graphic
image, I meant to say a disk linux image that would be loaded by the Live CD
isolinux.cfg file. How can I use i915 feature to load the disk image so that
it boots off a portrait display in portrait mode?

The motivation is to run linux on tablets that can be turned into portrait
mode. I think by using i915 feature, I maybe achieve this.

You have to resize the image beforehand.
