two framebuffer, console problem

Post by Matteo Scapuzz » Wed, 02 Jun 1999 04:00:00

Hi all,
Finaly I got Linux running on a friend's PowerMac.
I never had a MAC so I'm a bit a 'newby'.
The problem is that PC has two VideoCard,
The kernel says:
fb1 = valkirye
fb2 = ATY,mach64
vmlinux runs the console screen on the
valkirye card ( ...what a card is it? never heard
about it).
I would like to use the ATY Mach64 instead cos it's
First I guessed ( ...ROFL) some kernel boot options:
:) ... and similars
Next I recompiled the kernel turning off valkirye
support getting the final result of a BlackScreen
on boot.
How do I say to linux : run the console on the ATY card?
Thanks in advance.

Try video=atyfb. That might do it. The only way you would be able to
specify the OpenFirmware device like you did, would be to use them with
OpenFirmware (Cmd-CTRL-O-F at boot, really quick) and do some such like
'setenv screen ATY,Mach64' after you carefully examined the device tree.
But then, you'd have to setup a bunch of other options as well. BootX is
definitely the way to go.

1. Framebuffer console problems w/ Ati 3d rage II+DVD

Hi everyone!
Does anybody know how to avoid screen blanking when I try to set the
framebuffer console with loadlin?
I use this string :Video=atyfb,mode:1024x768,font:sun12x22,cmode:24,vram:4
with a kernel 2.2.10 (but i did it also with 2.2.7 and 2.2.9), and when I
set the hex value in the video selection menu (vga=ask) to 0318
(1024x768x24), the screen blanks and I can't see anything for the rest of
the boot...I heard it 's a quiet common problem, so maybe anyone here
already answered this question...

Pliz help!!
