Acceleration fails to work with Dual-Head configuration.

[Michael B. Trausch]

Binary package hint: xserver-xorg-driver-i810

This is a problem with the version of X.org distributed with Edgy; X.org claims in their bug that it is something to be fixed with the upcoming X11R7 7.2.0 release.

The problem is that 3D acceleration does not work (and crashes the X server with a signal 11 if use is attempted) when the i810 driver is using a dual-head configuration as would be used on a laptop computer. The machine that I am using is a Toshiba Satellite A55-S1064 with the Intel 915GM graphics chipset hardware.

Will attach the upstream bug report, which contains more information.

Can you upload a log file from /var/log/Xorg.0.log and it should have some more
detail on what's happening.

Crash log.

This is the log from when the X server crashed. Sorry for the delay, child was
pestering me. :) Configuration to follow.

Crashing configuration

This is the configuration which causes the X server to crash. All that needs
to be done to crash it is use this configuration, and use any program that
makes use of OpenGL. It is possible to work around this issue by either
removing the dual-headed portions of the configuration, or by stopping the use
of DRI by commenting out the DRI module. I am currently using my system with
the latter of the two workarounds, and at least for the moment, it seems
stable.

[Fd0man (fd0man)]

Altered summary; the real problem is that the dual-headed configuration does not
play nicely with DRI and OpenGL. When DRI is disabled, the dual headed
configuration (and OpenGL programs) work, though OpenGL programs run really
slowly (as one might expect).

This is a bug in the Xserver, which has been fixed in the upcoming 7.2 release.
So you may want to pull that.

Feisty has 7.2 now, with the latest stable i810 driver (1.7.4)

[Michael B. Trausch (mtrausch)]

Yep. And it works!
