Multihead in Debian/Debian-based distro and 64-bits?

[drbista <dr...@ep...>]

Dear friends:

Many greetings! I have created a dualhead in FC1 (thanks to Zoli). But I am 
trying to create one in Debian/Debian-based distro SimplyMEPIS. Before 
proceeding I have a few questions:

1) I have installed LTSP (ltsp.org) and three different terminals are being 
used in the current machine (PIII 1GHz 256MB). Could the ltsp and multihead 
coexist in the same machine? Anyone has experience?

2) I have seen instructions for debian multihead at 
http://www.c3sl.ufpr.br/fourhead/howto-en.php but it does not mention of the 
pci_isolate_device_feature.diff 
(http://www.ltn.lv/~aivils/files/080_pci_isolate_device_feature.diff) as 
stated in Aivils' site (http://www.ltn.lv/~aivils/eng-down.html). Any idea?

3) Whether it is necessary to make changes in the display manager? In my 
current SimplyMEPIS (debian-based) distro, I am using kdm. When creating 
multihead with FC1, I do remember that I made changes at gdm.conf under 
[servers].

4) I have acquired with much difficulty a PCI VGA card from Tseng labs (ET6000 
22a26K650). Does anyone have any experience about this card working with 
multihead?

5) May I have some contacts or sites which is peculiarly working on the 64-bit 
linux multiheads? Of course I know my dear friend Zoli from Hungary who has 
been active in FC3, but I want to know more who has been involved in debian 
or debian-based distros.

Thanking you for your time and cooperation. May all of you be successful in 
your missions, prosperous, free from sufferings, health, happy, and in peace, 
always!

Thanks. Have you ever tried with both (ltsp+multihead) on the same machine? 
BTW which distro you are using for multihead?

But I didn't see any mention of patched X server at c3sl site. And even Mr. 
Aivils Stoss specifically stated at  http://www.ltn.lv/~aivils/eng-xf.html 
that  "Since 15-MAY-2003 kernel patch You need not to recompile XFree86"

In any case, does anyone know where can I find the precompiled X-server for 
debian?

Anyone has any idea what are the changes to be made in kdmrc or other kdm 
related files? I checked 
http://www.tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/examples_dm.html but 
there is no mention of kdm-related stuffs besides gdm and xdm.

Any specific 64-bit multihead sites?

Probably no problem - just install both.  Problems happen only if
both programs wants to use the same hardware, I believe that
doesn't happen in this case.

When using debian, make sure you get your X from the testing
distribution. It makes sense to use the "testing" distro anyway,
as "stable" is so old.  The xserver from "testing" have
isolatedevice compiled in so you don't need to patch at all.
You can use stuff like
        Option          "IsolateDevice" "PCI:1:0:0"
in XF86Config-4 - it just works.

The screen section may need a
        Option          "InitPrimary" "on"
for xservers running on secondary graphichs cards (i.e. those cards
not initialized by the bios.)

You make changes to gdm.conf if you use gdm.
When you use kdm, you make changes to the kdm config file instead.
(Or xdm config files, for those who use xdm like I do.)

Not me.  I use a Matrox G550 AGP and a Radeon sapphire 9200 SE PCI.
One problem here - the radeon xserver is unstable and hang itself
(and sometimes the entire pc) occationally.  Bad hardware or bad driver,
I don't know.  I got a radeon because they were supposed to work well
in multihead configurations, even with 3D.  Unfortunately, it is older
radeons that work well. . .

I'm trying to get 64-bit going (amd64) but I'm going slowly.  There is
so many other things to do. :-/   I am currently stuck with 2.6.8.1
because later kernels simply hang when X tries to initialize the
PCI radeon.  [Not a ruby problem, it happens with plain 2.6.9 too. :-(  ]

dpkg -l shows these two entries under xserver:

xserver-common 4.3.0.dfsg.1-6 files and utilities common to all X servers
xserver-xfree8 4.3.0.dfsg.1-6 the XFree86 X server

Does the above contain the isolatedevice feature built-in?

I read at the 
http://www.tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/dm_conf-xdm_kdm.html 
this:

<QUOTE>

Debian uses:

    *

      /etc/kde3/kdm/Xservers for kdm 

you can make a backup copy of /etc/kde3/kdm/Xservers and make a symbolic link 
from /etc/X11/xdm/Xservers to /etc/kde3/kdm/Xservers, in order to use the 
same configuration file for xdm and kdm.

<UNQUOTE>

Does this still implies?

I am trying to test with the built-in i810 16MB AGP and a S3virge card.

gdm is recommended because the way it starts the

A peculiar question, does the patched kernel 
( http://www.c3sl.ufpr.br/multiterminal/kernel-image-2.6.7-ruby.tar.bz2) at 
http://www.c3sl.ufpr.br/fourhead/howto-en.php when installed with dpkg -i 
command would install in parallel with the existing 2.6.7 kernel or replace 
the existing one? Any idea?

I wrote to the c3sl but yet to get any response for the last 48 hours! :-(

Thanks for help.

If /lib/modules now has /2.6.7 then after installing
what you cite with dpkg -i would probably install
2.6.7-ruby. But you can tell beforehand by examining
the .deb see man deb.

In any case I had better results with 2.6.9 Ruby, but
that was with a regular 32 bit kernel of course.

In Debian compiling a kernel is trivial with the
kernel-package package. Perhaps you know. "make-kpkg
--revision 1 kernel_image" gets you the deb in the
/usr/src dir. Get the .config file from /boot and
adjust with make menuconfig in a vc.

With 2.6.9 I was able to use the Debian source of the
kernel and use Ruby (i.e the 2.6.9 vanilla kernel and
the Debian patches added) but it will depend on the
kernel and if it does not fit you will have to use the
vanilla kernel. Sorry if this has been said already
and I am duplicating information. Aivils seems to
think that the main problem is the video cards. If I
were to do it over again I would first experiment with
many of those. As it is I only have 2 nVidia cards, so
funny looking garbage remains a questionmark...

I tried to install the precompiled kernel 
( http://www.c3sl.ufpr.br/multiterminal/kernel-image-2.6.7-ruby.tar.bz2) and 
it get installed as a parallel kernel, but it gave some errors like below:

<QUOTE>

You are attempting to install an initrd kernel image (version
2.6.7-ruby) but you do not seem to have a mkinitrd command in the
path. This will break the installation, unless initrd-tools are also
being installed right now.


Could not find mkinitrd in path. at /var/lib/dpkg/tmp.ci/preinst line 189.

You are attempting to install an initrd kernel image (version 2.6.7-ruby)
This will not work unless you have configured your boot loader to use
initrd. (An initrd image is a kernel image that expects to use an INITial
Ram Disk to mount a minimal root file system into RAM and use that for
booting).

   As a reminder, in order to configure LILO, you need
   to add an 'initrd=/initrd.img' to the image=/vmlinuz
   stanza of your /etc/lilo.conf

I repeat, You need to configure your boot loader -- please read your
bootloader documentation for details on how to add initrd images.

If you have already done so, and you wish to get rid of this message,
please put
  "do_initrd = Yes"
in /etc/kernel-img.conf. Note that this is optional, but if you do not,
you will continue to see this message whenever you install a kernel
image using initrd.
Do you want to stop now? [Y/n]n

(I tried to continue with the n option and got the following)

And when trying to boot in the ruby image, it gave me kernel panic error 
saying the kernel could not find the place to mount....

Any idea? Thanking you in anticipation,

Right. It tells you exactly what is wrong. At the risk
of repeating what you perhaps already know, Debian
kernels ship with what is called a cramfs file with
modules that avoids them filling up the kernel and
support the world and then some. This is invoked via
what is called "initrd". Use of this necesitates a
package:

http://packages.debian.org/testing/utils/initrd-tools

and what the messages told you is that you do not have
that package installed.

Install it and at least you won't get that error
anymore...
