[Linux-fbdev-users] Latest FBDev patch

[Kilian C. <kil...@cr...>]

Hi all,

First of all, my problem : I have a Dell D800 laptop (the problem is not
here ^_^), with a wide 1920x1200 screen, and I'd like to run a
framebuffer console in this mode, with a 2.6.x kernel. The video card is
a nVidia GeForce4 Ti 4200 Go, and
my X server uses the following modeline :
"1920x1200" 162 1920 1968 2160 2176 1200 1201 1204 1206 +hsync +vsync


Then , my experiments.
I tried to use :
- vesafb driver, from vanilla 2.6.1 : it runs ok in 1600x1200 (with
vertical black bars, each side of the screen), since 1920x1200 is not a
'standard' VESA mode. I think it would be possible to add this 16:10
mode in modedb.c, or whatever vesafb uses, but I'm not experienced
enough too really do it.
- rivafb driver, from vanilla 2.6.1 : does not detect any framebuffer
device at all, and run in plain old 80x25. Not what I want.

So, I just tried the latest FBDev patch from James Simmons :
- no change with vesafb, since I don't know which code I could put in
the vga= kernel option
- rivafb gives me no ouput at all : after decompressing the kernel
image, when it usually switch to fb mode, the screen remains blank, with
only two small colored dots, flashing middle left and up right of the
screen. Not very usable. :)

So I'd like to know :
- is this video card supported by the rivafb driver ?
- is it possible to add the 1920x1200 mode, for vesafb to use it ?
- how can I help to add support for this configuration ?

TIA,
