Two monitors, one at a time

[Pedro H. <ph...@ya...>]

I am trying to set up a box with two monitors. I have compiled both
2.4.27 and 2.6.9 but reached best results with the latter. However, I
have some problems.

Using grub I have append=”dumbcon=3” but when I try to start X with a
vt higher then 16, X says that the vt doesn't exist. Don't know if it
is important.

The USB keyboard doesn't show up in /proc/bus/console/*/* (the serial
is there and a line with VGA+. I can use the USB with “Dev Phys” so it
isn't that dramatic). Am I missing something while compiling the
kernel?

When I start the second instance of X the first monitor goes black. I
can switch back to the first, but then the second goes black etc. Since
I haven't been able to find the patch for X nor a precompiled one, I am
using unpatched X with Option "PciOsConfig" "1" in both config files. I
also do “echo “1” > /proc/bus/pci/hackvideo” before I start X. What may
be the cause (Kernel is wrong configured, the hardware, is it that I
use unpatched X or something else)?

Using sis (SiS 300 I think) and nv (GF400) drivers for the video cards
and Debian Sarge. I have tried precompiled kernels from Andreas
Schuldei: with 2.4.21 my box doesn't boot and with 2.6.0 X doesn't
start. It seems that Schuldei have made precompiled Xfree86 available
for debian, but not sure how to use or if it is good for sarge (can't
use sid).

Any help would be much appreciated and my apologies if this post is
inappropriate for this list.
