log showing the crash
Running further tests for #19412, I recently upgraded my intel driver to 2.6.1.
Now with that version I cannot even start X when I have configured an external monitor, may it be connected or not. X dies like this:
(EE) intel(0): Failed to pin front buffer: Cannot allocate memory
Fatal server error:
Couldn't bind memory for BO front buffer
Please consult the The X.Org Foundation support
Please also check the log file at "/var/log/Xorg.0.log" for additional information.

Caught signal 11. Server aborting
Having the external monitor as a clone of the panel, the driver does not fail.

This seems similar to bug#17490. You can try decreasing Virtual setting. (If your laptop panel is 1920x1200, you can try set them as up-bottom so "1920 2250" is sufficient)
And you don't need screen1. You can refer to http://intellinuxgraphics.org/dualhead.html for how to write xorg.conf for dualhead.
thanks for your quick reply.
Yes indeed, changing the layout to up-bottom instead of left-right dualhead is working. So this is a bug in the driver, right?
And per my "screen1" section, yes I know, it is unnecessary for "plain" dualhead configurations. It is a remainder of some tests to set up a zaphod style dualhead configuration, but that failed as well & certainly is another story ;-)

So this is exactly bug#17490 and fixed in DRI2.
It should work if you use xf86-video-intel 2.6.x + xserver 1.6 + libdrm 2.4.4 + kernel 2.6.28.
*** This bug has been marked as a duplicate of bug 17490 ***
hmm, I don't think that it is a duplicate, here is what I've got running:
$ rpm -q lib64drm2
$ uname -a
Linux localhost 126.96.36.199-desktop-2mnb #1 SMP Fri Jan 23 14:26:25 EST 2009 x86_64 Intel(R) Core(TM)2 Duo CPU T9400 @ 2.53GHz GNU/Linux
$ rpm -q x11-server-xorg
and the 2.6.0 version of the driver worked for me, so there must at least be a regression somewhere, alas reopening.
Eric, so it's said to be a regression from 2.6.0 to 2.6.1.
I ran some additional tests on this and after changing from EXA to UXA made the bug go away as well, so looks like an EXA only problem.
Reporter says it's fixed with moving to UXA.
