Re: [Linux-fbdev-devel] Dual display on framebuffer with i810e andET6000

[Herman T. <HEt...@cs...>]

Makes sense.

I changed my BIOS setting to choose the ET6000(pci device). When the =
kernel boots, the system loads the VESA framebuffer (showing the bootlogo).=


OK. I compiled my kernel with module support for the i810fb.
I login as root, then do a modprobe i810fb. The module gets loaded(lsmod), =
and dmesg says(i810 ... loaded). cat /proc/fb gives something like:
0: VESA
1: i810
(this is just out of my head).

So it looks as if everyting is fine. What am I supposed to see in the =
screen connected to the i810 adapter when I insert the module? It doesn't =
look like if the adapter gets initialised since my monitor's led stays =
yellow(which normally turns green when the adapter is working). Windows =
normally display a message to say that "if you can see this message, ... =
adapter is initialised..." or something to that effect. Can we do the same =
for Linux?

The reason whyt I say this is after I insmod i810fb, I want to map a =
virtual console to the i810fb. I used con2fb:

con2fb 1 2

to map virtual console 2 to frame buffer device 1(/dev/fb1)

But, I see nothing happening on the screen connected to the i810fb. The =
screen stays blank. Am I missing something??

Thanks for the help.
Herman

It depends on how much the graphics hardware depends on the BIOS.=20

Which means that the ET6000 has to be the first card initializied in your
system. VESA always maps to this. The i810e will have to be your secondary
card. Look in your BIOS to see if their is a option to select which card
gets booted first (AGP or PCI). Make sure the PCI is booted first. You
have to do a few tricks with con2fb or use the map setup option to get the
right VCs maps to the right framebuffer devices, but that is the easy
part.

It would be nice to have a ET6000 driver :-) I never found docs for this
card tho :-/
