Here's a patch against the jaunty xserver. Doubt it could hurt to have
an extra nullptr check here, and if this bug still exists with jaunty,
this patch would stop the segfaulting.

Even though this is really a wishlist thing, patching to fix the
segfault looks pretty easy...

It's not going to work until upstream has finished laying the groundwork
for some infrastructure. Maybe for Hardy+1, more likely Hardy+2.

I see the same behavior with ATI Mobility Radeon X300. package versions:
xserver-xorg 1:7.2-5ubuntu13
xserver-xorg-video-ati1:6.7.195-1ubuntu2
Also, I used to work with two external monitors with my T43 laptop.
After the latest upgrate, I am unable to get one of the monito
I also can confirm this with an NVIDIA 6150 integrated chipset when
trying to setup dual screens (default=1280x800, and 1280x1024 external
monitor) when using the Gutsy screens and graphics tool with restricted
driver enabled. After X is restarted, both screens dump to highest
resolution specified,
I succeeded to get a core dump.

I found some more info of the crashing with ’intel’ driver:
(EE) intel(1): Internal Error: maxCacheLines < 0 in i830_allocate_2d_memory()
(II) intel(1): Allocating 0 scanlines for pixmap cache
Backtrace:
0: /usr/bin/X(xf86SigHandler+0x6d) [0x48670d]
1: /lib/libc.so.6 [0x2ad8a23777d0]
and so on.
Seems that this happens also with other dual screen configurations.
When using only the intel chipset backtrace is longer:
0: /usr/bin/X(xf86SigHandler+0x6d) [0x4866cd]
1: /lib/libc.so.6 [0x2adf867897d0]
