Bug#546586: xorg: X server lockup in int10 when booting a secondary card

["Mader, Alexander" <aumader@gmx.net>]

Subject: xorg: X server lockup in int10 when booting a secondary card
Package: xorg
Version: 1:7.4+4
Severity: important

Hello,

I just run aptitude upgrade and my multiseat setup isn't working any
more. The
experience is as described in freedektop.org bug 18160. I would prefer
helping with a solution rather than being forced to downgrade xorg.

In more detail: On an old AMD K7 I was running a multiseat setup with an
equally old NV34 [GeForce FX 5200] rev 161 and an ATI Technologies Inc
RV 610LE PCI [Radeon HD 2400] rev 0. First a Dummy X server was started,
then the X server for the primary AGP NVidia card, and then the X server
for the secondary PCI ATI card. After the upgrade the first two X servers
start but the third hangs after loading int10.

I will attach the xorg.conf files and the logs later.

Best regards, Alexander.
