[PATCH] Updating Documentation/fb/vesafb.txt

Hello Antonino,

I recently tried to figure how to get my vesafb to 1600x1200 and updated the 
vesafb.txt documentation accordingly. I'm still not sure about the video mode 
for 256, since it doesn't seem to follow the algorithm the other vga-modes 
seem to follow.

Example:
    | 640x480  800x600  1024x768 1280x1024
----+-------------------------------------
256 |  0x301    0x303    0x305    0x307     | +0x002
32k |  0x310    0x313    0x316    0x319
      -------  -------  -------  -------
      +0x009    +0x010   +0x011   +0x012

So accordingly to that algorithm, the mode for 1600x1200@256 should either be 
0x309 or 0x360 which both don't work.

Find attached the mentioned patch to update vesafb.txt.

Please CC me on replies, since I'm not subscribed to the list.

 To enable one of those modes you have to specify "vga=ask" in the
 lilo.conf file and rerun LILO. Then you can type in the desired

This is not correct. VESA did not define 1600x1200 as part of
its DVT standard. And starting with VBE 2.0, VESA is not going to
define new mode ID's. Thus the mode ID that you get for 1600x1200 may
be unique only for your particular hardware/Video BIOS.

You may use X's 'vesa' driver to get a list of modes that your
BIOS supports. It will be written to /var/log/X*.0.log.
