Hi All,
I'm experiencing odd behaviour with various OpenGL apps I'm (trying to)
use. I have an IBM Thinkpad X60s with the Intel GMA chipset, the 945GM
to be precise. I have glxinfo/glxgears working normally, disabled
composite in xorg.conf and everything seems fine.
However, there are a few applications that I use that show rather
strange behaviour that I think is related to the same underlying (as yet
unidentified) problem. Here is my list:
* Google Earth 4.3
Installed in /opt/googleearth. Starts, but with extremely slow
performance. Unusable, Closing the window takes about 10 seconds.
* OpenOffice 2.4.0
Installed in /opt/openoffice. Failed to start when using the "intel" or
"i810" Xorg driver. "vesa" driver works fine. Later learned that setting
GTK_MODULES="" works around the problem while using the "intel" or
"i810" drivers and that it might have to do with the gnome integration
stuff in OpenOffice.
* Maya 2008
Installed in /opt/maya. Fails to start (sig 11) when using the "intel"
or "i810" Xorg driver. "vesa" driver works fine (but with abominable 3D
performance obviously). A gdb backtrace tells me:

I'm fairly sure this has something to do with the mesa 3d driver for the
Intel 945GM but I cannot confirm this and I would like to search
further. Does anyone have any suggestions as to where I could look next?
Thanks in advance,
Kind regards,
Rurib.
