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: #0 0x00000000 in ??

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.
