Description Dave Mitchell 2007-11-16 21:39:52 UTC

Description of problem:

A laptop works fine with an external LCD monitor. However, when trying to
congigure dual-head, the X server crashes during startup. The stack trace
indicates that thre segfault happens in the driver. Initially it was using the
"intel" driver; when I switched to the "i810" driver the same thing happened
(this time the segfault in the i810 driver). I attach two xorg.conf files and
associated log files.

Version-Release number of selected component (if applicable):

xorg-x11-drv-i810-2.1.1-7.fc8
xorg-x11-server-Xorg-1.3.0.0-33.fc8

How reproducible:

use one of the attached xorg.confs, and try to start X.


Steps to Reproduce:
1 as above

  
Actual results:

Additional info:

This same laptop worked fine under FC5 dual-head with and external CRT. Since
the upgrade to F* and replacing the CRT monitor with a 1440x900 LCD its been
failing. NB - the laptop is a Dell D400 with a 1024 x 768 display.

Comment 5 Artem 2007-11-19 13:00:44 UTC

I have the same behavior with HP compaq 6230 laptop

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS, 943/940GML
Express Integrated Graphics Controller (rev 03)

I'm able to get second monitor (external) working with i810, but not able to
make it not to be clone of LFP. In any configuration (using Xinerama or not,
"Clone" "off") DFP is clone of LFP.

Comment 6 Jesse Barnes 2008-01-10 23:45:37 UTC

Looks like the config for the 'intel' driver is a bit off.  Try the 
instructions at http://www.intellinuxgraphics.org/dualhead.html instead.  Note 
that zaphod mode isn't support atm, so if you're trying to do that, this is a 
dup of 239332.

Comment 7 Dave Mitchell 2008-01-19 23:33:27 UTC

Well, having read the the instructions at that URL and having tried playing with
xrandr, I find that xrandr claims that the maximum screen size I can have is
1360 x 1360, and thus won't allow me to achive my minimum desired goal of 2048 x
768 (ie two 1024 x 768 screens side-by-side). Note that my hardare (intel
852GM/855GM) is capable of supporting this, as I used to be able to do it with a
pre-xrandr xorg.conf setup under FC5 (admittedly with an external CRT rather
than the external LCD I have now).

Any suggestions?

Here's the output from xrandr:

Comment 8 Jesse Barnes 2008-01-21 16:57:08 UTC

Looks like you need to add a 'Virtual' option to your screen section (see the 
end of the "static configuration" example on the dualhead.html page).  
Hopefully that'll clear things up for you.  If so, please close this one out.

Thanks,
Jesse
