Re: Using two dual-head Radeon cards with X on a single PC with 3 monitors

Shouldn't the -isolateDevice be used in order to avoid
the X servers disabling the other card? Also you may want to make
them share a common VT (although I am not sure if this is necessary
in dual-head setup as opposed to dual-seat). In my dual-seat desktop,
I use the following command lines:
X :0 -layout Primary -isolateDevice PCI:1:0:0 vt7
X :1 -layout Secondary -isolateDevice PCI:5:0:0 -sharevts vt7
(the -layout option is analogous to your -config, but allows you to share
a single xorg.conf file for both X servers).
However, I had problems with my multi-seat desktop with 2.6.39
and newer kernels, so you can also try to downgrade the kernel. 2.6.38
works for me. FWIW, the Fedora bug report I have filled is here:

Fedora ships the second one:

A colleague told me that this is true also for Ubuntu (so
presumably for Debian too).

With recent versions (I use Fedora 10,
xorg-x11-server-Xorg-1.5.3-6.fc10.x86_64,
xorg-x11-drv-ati-6.9.0-63.fc10.x86_64) - I am able to POST even a secondary
card. It is (and always has been, AFAIK) dependent on the order in which
you start the X servers.
In my old configuration (32-bit, Radeon 9200 AGP + Riva TNT2 PCI)
restarting the ATI X server froze the Riva X server, but I could restart
the Riva at any time without affecting the ATI session.
With my current setup (64-bit, two ATI Radeon HD 3450 PCIe cards),
POSTing the secondary card resets also the primary card (so the primary
X server has to be started last, which is what xdm does), and worse even,
terminating the secondary X server locks up the computer altogether
in a similary way to what you have described (no response to KBD LEDs,
no response to ping, no reboot when echo 10 /proc/sys/kernel/panic.
BTW, what approach do you use for sound? I would like both users
to use sound to their own stereo speakers, so probably split a 6-channel
sound card output to three independent virtual stereo outputs via global
(not per-session) pulseaudio daemon?

Thanks for the explanation. One question, though:
is there a way of using HAL-managed devices in multi-seat X? If yes,
how can I specify which input device belongs to which seat?
I use static devices in Xorg.conf so far, but I would like
to have it working even after unplugging/replugging the input device.

Please add your HW details to the following bug:
https://bugs.freedesktop.org/show_bug.cgi?id=18160
As for the band-aid fix, downgrade to Fedora 8 version of the X server
and all dependencies (drivers, mesaGL, ...) still works for me.
I have not got much time to test it on F10 as well, but
_apparently_ with my setup it is slightly better - the secondary X
server does not lock up inside int10, but (despite -isolateDevice PCI:05:00:00
in the command line) it POSTs the _primary_ card instead :-(.
I will test it further and update the info in the above bug.
I have read that one of the goals of Fedora 11 is to have
a working multiseat operation, but I think it is impossible to do
without fixing Xorg first. It has been broken since 1.3 (1.3 was OK).

int10 broken? (using secondary card)
Hello,
a few months ago ago I wrote to this list that I had to revert to the
Xorg-1.3.0 (Fedora 8 version), because my secondary X server (in a multi-seat
setup) locked up in the int10 module when starting up. This was with nVidia
Riva TNT2 card, and the nv driver. Few days ago I bought a new computer with
two identical ATi Radeoh HD 3xxx PCIe cards, and there is the same problem:
the X server for the secondary card cannot be started (with or
without -isolateDevice).
Both radeon and radeonhd drivers work on the primary card
without a problem. However, when I try to run it on a secondary card
with the same Xorg.conf except the different BusID line,
the radeon driver locks up inside the int10 module (the int10 message
is the last one in /var/log/Xorg.1.log). With Option noint10 yes
it complains that the card has not been POSTed yet (no surprise here).
The radeonhd driver crashes after saying that it cannot read the atombios
values correctly.
So my question is: does the int10 module work in the recent Xorg
servers? If not, can I somehow POST the secondary card manually?
Thanks,
-Yenya
