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.

It is quite important.
# cat /proc/cmdline
command should show kernel startup commandline. You can make
sure dumbcon parameter.

Here should exist multiple directories
/proc/bus/console/00
/proc/bus/console/01

# cat /proc/bus/input/devices
shows USB devices ?

Looks like You use standard kernel, which one not allow multiple
current /dev/ttyXX
# uname -a
shows kernel version.=20

Motherboard built in video (SIS) will not work :(  You will borrow
addtional video and check it out.

Yes, the commandline for grub was wrong. now that it is corrected
everything (that I have tried) is owrking just fantastic. It is really
a great feature!

There is one thing though, in dmseg I have this:

Device 'i823650' does not have a release() function, it is broken and
must be fixed.
Badness in device_release at drivers/base/core.c:85

Do you know if it's related to the ruby patch? I haven't had time to
check it out, but I'll try to next week.


Thanks for your help, and thanks a lot for your work in ruby!!!

Hi friends,

I'm work with six-head. I attached XF86Config and gdm.conf for your
example.

For me at least, it would be interesting to know:
* What hardware are you running (cpu, ram, motherboard)?
* Monitor cables are usually not very long. Have you extended them, 
  and if so, how long and do you know how long such cables can they be?
* What window manager do you use?
* How does the system respond if all user uses a lot of resource
  consuming processes (mozilla, openoffice...) at the same time?

Thanks for your time

I'm running six-system with athlon 2.2, 512Mb and mother board GigaByte
(chipset Intel, sis and via)

It's very problem, I find that with 6 meters he functions well. In my
office we user in mode circle.

Initialing with XFree86 4.3 and now Xorg.

To my surprise this resource is very very fast, in percent more or less
20% more slow compared with standalone machine.
