FBCON - vesa graphics modes no longer work on Toshiba Laptop

FBCON - vesa graphics modes no longer work on Toshiba Laptop

[Sean Estabrooks]

Toshiba Satellite 4300 laptop with the following display adapter:

S3 Inc. 86C270-294 Savage/IX-MV (rev 11) 

2.4.20 kernel works well with vga=0x305 and uses the entire LCD panel.

2.5.67 kernel with vga=0x305 sets a graphic mode that only uses the
inner 640x480 set of pixels and the display is just a jumbled mess.  

I did try the latest fb patch and the problem remains.  Also found a
note that said to try "video=vesa:ywrap,pmipal,mtrr" and this didn't
work either.

Regards,
Sean

Why don't you add vga=791 video=vesa:1024x768 to the kernel boot line
and enjoy.  And next time maybe you should try to figure it out for
yourself just a little bit longer before asking the list.

Try disabling CONFIG_VGA_CONSOLE. Tell me if this fixes all your problems.
