Description Mathieu Chouquet-Stringer 2004-08-27 18:08:00 UTC

I just upgraded my box from Fedora Core 2 to dora Core release 2.90 (FC3 Test 1)
with the latest updates (xorg-x11 version 6.7.99.902-8).
My setup was working perfectly in Core 2 but it's no longer the case.

This PC has a PCI Appian graphic card: 2 radeon gpus that output to four
screens. This setup was working perfectly but now, only 3 out of the 4 screens
(3 LCDs and one plasma screen) are usable. I say usable because the last one,
albeit on, just displays a blank screen (ie I'm able to send windows or the
mouse pointer there but it's kind of a black hole as I can't see anything).
This monitor (a dell lcd in this case) is on, ie it "sees" a signal at this
point (and is on).

Moreover, I can't switch back to the virtual console, I only get garbled output
on the screens (this also used to work with the xorg version present in Core 2).

This behaviour is totally reproducible across restarts.

I can provide more details or help debuging stuff, just let me know.

I'm also attaching my xorg.conf and Xorg.0.log.

Comment 3 Mathieu Chouquet-Stringer 2004-08-30 05:45:27 UTC

Just tested 6.7.99.903, same result.

Comment 4 Mathieu Chouquet-Stringer 2004-09-07 14:13:03 UTC

It works again with version 6.7.99.903-5 (that's the rpm version).
I'll be resolving this ticket if I don't hear from anyone before the end of the
week (I found strange no one even picked it up).

Comment 5 Mathieu Chouquet-Stringer 2004-09-09 03:36:59 UTC

As per my last message I'm resolving this problem.

Comment 6 Mathieu Chouquet-Stringer 2004-09-10 06:32:11 UTC

Doesn't work with 6.7.99.903-6, hence reopening this bug.

Comment 7 Alex Deucher 2004-10-08 06:56:25 UTC

this may be related to bug 1559

Comment 8 Mathieu Chouquet-Stringer 2004-10-14 17:37:33 UTC

Not sure as with the latest updates (6.8.1-4 on Fedora), there seems to be a
misdetection of the memory area: 1 monitor is still not being detected/activated
but on the 2 that are on the same chipset, i've got overlap at the bottom of the
screen (ie a rectangular area is actually from the "other" monitor, like having
the "other" on top of the main one).
Interestingly enough, if I start xfree 6.7.0, kill it and then upgrade to 6.8.1,
as long as I don't reboot, 6.8.1 will work fine: definitely something in the
initialization of the card.

Comment 9 Chris Hubick 2004-12-08 14:02:55 UTC

Thanks again to Mathieu for bringing this to the attention of those of us over
in the downstream Fedora bug for this:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=138479

Just crosspolinating links to make sure devs and users have access to all the
reported info :)

Comment 10 Mathieu Chouquet-Stringer 2004-12-21 08:12:46 UTC

Just tested 6.8.2rc1 a.k.a 6.8.1.901 by Mike A. Harris.

We're almost there. 3 out of the 4 displays are working. The last one is on but
displays nothing (black screen).

On the plus side, the memory detection seems to be ok as I don't get this
overlap anymore at the bottom of the screen.

I'm attaching log file for 6.7.0 and 6.8.1.901 and a diff between these two.

Comment 14 Mathieu Chouquet-Stringer 2005-01-18 06:06:10 UTC

Tested with xorg version 6.8.1.902-1 (6.8.2rc2, rpms in rawhide by Mike A.
Harris), same thing.

Comment 15 Ross Beyer 2005-03-30 12:24:46 UTC

I have encountered a similar problem on my system.  I have an ATI Fire GL Z1 
card with dual DVI outs.  When I use a Dual-headed layout, I get a desktop on 
the primary monitor, and the secondary monitor indicates that it is getting 
some kind of signal, but the screen remains blank.  My Xorg.0.log file 
indicates that it is getting EDID data from the second port, but then it gives: 
 
(WW) RADEON(0): Failed to detect secondary monitor, MergedFB/Clone mode 
disabled 
 
I was hoping that 6.8.2 would fix it, but it doesn't.  Like the Fedora bug, I 
tried goofing with MergedFB, DDCon, and MonitorLayout, but to no avail 
(however, I may just not know how all of that stuff fits together, the radeon 
man page is descriptive, but a how-to would be nice). 
 
The kicker is that on a previous computer (with the same ATI card) last fall 
(Xorg from September 2004, don't know the version), the dual-head worked just 
fine. 
 
I'm happy to upload log files and configuration files, if that is needed.

I can also confirm that this still doesn't work with 6.8.2.  It does work just
fine with the 6.7.0 RPMs from Fedora Core 2 - I would presume any 6.7.0 varient
would also work.

Same here (just tried the 6.8.2-1.FC3.13 RPMs for Fedora Core 3).
I'm attaching a diff of Xorg.log between version 6.7.0 and 6.8.2.

Comment 20 Keith Packard 2005-03-31 12:33:49 UTC

I'm having similar trouble on a pair of FireGL V7200 (R423) UQ (PCIE) cards
(pci id 1002:5551).  Dual DVI outputs + SVideo.  DDC correctly detects both
panels, but the secondary panel doesn't see any signal (not just blank, no
signal at all).

I tried both MergeFB and regular multi-screen mode with the same results.  I
also tried two different panel models on the secondary head.

Comment 21 Mathieu Chouquet-Stringer 2005-05-06 09:01:00 UTC

Is there anything we can do to help debugging this problem? Because it makes
current version of xorg rather useless on these kind of setups.

Let us know, I'm sure a lot of us would like to get this fixed.

- Mathieu

Comment 22 Mike A. Harris 2005-05-10 23:15:41 UTC

Sure, if someone who experiences the problem is willing to debug it
and attach their results, that would be a big help.  I doubt many
developers working on Radeon driver outside of ATI have access
to quad-head Radeon hardware, so unless it's a problem that also
affects something on more common hardware, it's probably going to
be difficult for someone else to debug it.

Have you tried CVS head Xorg?  Might want to try that first in case it works.

The easiest way to debug the server, is to recompile it static-only,
and use standard gdb over the network from a second computer (required).

There are a few debugging guides on freedesktop.org IIRC, probably locateable
via google.. sorry I don't have links handy..  You might want to drop by
#xorg-devel and/or #freedesktop on irc.freenode.net also, to discuss with
other devs.

Hope this helps.

As I mentioned in the linked Fedora Core bug report (and apparently failed to
mention in this one), I have an ATI FireGL Z1-128 dual-head DVI card and
experience what sounds to be the same problem: my first display comes on and
shows the first half of my desktop but the second (and last) display never
initializes.

Comment 24 Mathieu Chouquet-Stringer 2005-05-11 07:41:31 UTC

Mike, I just compiled xorg from CVS head but I've got one question: by static,
you mean defining DoLoadableServer to NO in the definition file, correct?

Next step will be to set up the remote gdb thing.

Comment 25 Mike A. Harris 2005-05-11 19:33:45 UTC

Yeah, you want a static server, rather than a modular one, because you
can't debug the modular server with gdb -> it can't resolve symbols
in the modules.

There are patches for older versions of gdb to make it be able to deal
with the X server, but the patches are kindof hackish and were rejected
outright from upstream gdb project.  As such, it's a pain to maintain
the special X server patch for gdb and so nobody keeps it working with
newer versions of gdb.  I kept it working for 5.0->5.1 or thereabouts
and then gave up as it was too much effort to bother with.

I've filed an official enhancement request for gdb to get support
for debugging the X server implemented in a way the gdb developers
feel is generic enough and clean, and I've been told by our gdb
developers about 10 times in the last 2 years "we'll be working on
this soon", but quite frankly I've lost faith in it ever happening
at this point, because it's considered low priority and gets pushed
out of the way for more important gdb features.

Kindof unfortunate, but ah well.  Future Xorg releases will use
dlopen() so the problem should just go away in X11R7 and later, and
we'll be able to use stock gdb.  ;o)

For now though, it's just much easier to debug the static server than
to play games patching gdb.  ;)

Hope this helps.

Comment 26 Merit WIlkinson 2005-08-15 10:57:43 UTC

Just a note for people having trouble getting multiple cards to work:
Try setting
  Option  "InitPrimary"   "Off"
  Option  "NoInt10"       "On"
in the DEVICE section of your secondary cards.
We have a Colorgraphic Xentera GT which is an 8 head card composed of 4 Radeon 
M9 chipsets and this did the trick for us.

Did anyone else find that this solved the problem for them?

Comment 28 Ken Kennedy 2005-09-27 06:15:01 UTC

I just discovered a workaround over at RH's bugzilla that worked for me. I have
a Radeon X300 SE, with dual DVI outs. Like several others here, hen I use a
dual-headed layout, I get a desktop on the primary monitor, and the secondary
monitor indicates that it is getting some kind of signal, but the screen remains
blank. The desktop exists for the second monitor, though...you can move the
mouse there, and also open windows there (which can be a pain. *grin*). 

In searching for bugs on this issue, I came here, and eventually also bounced
over to https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=138479. At the end
of that  ticket, Stephen Adler has a similar problem, and a successful workaround:
" The way I made my second screen work again was by disabing and
re enabling the screen saver, going through the preferences memu.

Applications->Preferences->Screensaver
"

I tried it as well, and it worked for me like a champ. Bizarre! Just wanted to
share the love. Thanks to all for the good info.

Comment 30 Erik Andren 2006-05-10 05:55:03 UTC

Any improvements using a more current version of xorg?

Comment 31 Chris Hubick 2006-05-10 06:27:49 UTC

(In reply to comment #30)
> Any improvements using a more current version of xorg?

As I reported in the Fedora bug linked from comment #9, I was not able to get my
FireGL Z1 to work at *all* with the radeon driver on a clean Fedora Core 5
install  on my dual DVI workstation - I had to install via text mode and switch
to binary drivers.  Others there reported sucess though, so who knows.  The FC5
install CD won't boot to X, but the FC4 CD still does (though dual DVI didn't
work there, just single head).  IIRC Dual DVI hasn't worked for me with the
X.org driver since FC2 :(

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.
