[Bug 202164] [NEW] [hardy] displayconfig-restore causes X to crash

[laga]

Public bug reported:

Hi,

I'm using a multiseat setup. The primary VGA card is a Nvidia 7600GS
with the proprietary driver (nvidia-glx-new), the second card is a ATI
Radeon 9250 PCI using the free driver. After the upgrade to Hardy, the
second X server will repeatedly use lots of CPU and crash almost
immediately. It starts using a lot of CPU as soon as displayconfig-
restore is run. If I run chmod -x /usr/bin/displayconfig-restore, X
works just fine. I've tried disabling various calls in displayconfig-
restore but I never found out which one was actually causing the
crashes.

Here's the backtrace I'm getting from the second X server:

Backtrace:
0: /usr/bin/X(xf86SigHandler+0x6a) [0x48401a]

7: /usr/bin/X(FontFileCompleteXLFD+0x279) [0x435ed9]

Fatal server error:
Caught signal 11.  Server aborting

I'll attach my xorg.conf and my Xorg.1.log file.
