Hi Murray, The is known bug in NVidia drivers related to glXWaitVideoSync and 8800GTS. You could try commenting the associate lines out of Producer.
The other alternative would be to do update to the CVS version of the OSG. The new osgViewer that functionality replaces osgProdcer doesn't use glXWaitVideoSync (although I may add it as an option later, but it won't be on by default). Robert. On 2/13/07, Murray Curtis <[EMAIL PROTECTED]> wrote:
I'm getting a blank window when running osgviewer on a new hardware installation. The installation process was first tested on my existing hardware and works just fine. Both systems are running Ubuntu 6.06 and are installed from the same CD/respositories. OSG is version 1.2. The driver is Nvidia 9746. Old (working hardware) Intel P4 on 925 chipset with Nvidia 6800GT New (not working) Intel Core 2 E6600 on 975X chipset with Nvidia 8800GTS If I set OSG_NOTIFY_LEVEL to DEBUG_INFO the last message is: OsgCameraGroup::realize() _threadModel==Producer::CameraGroup::SingleThreaded (that's all in one line) On the working hardware the next lines are: entering 0x8084640 init. running 0x8084640 init. OpenGL extensions supported .... (long list of GL extensions) So it seems to fail when someone (OSG?) starts probing the OpenGL driver for its capabilities. OSG linked OK when I compiled it, ldd reports the same links on both systems. Other GL programs seem to run OK; Celestia, glxgears, the GL screen savers. I get the Nvidia logo on starting X and glxinfo reports "direct rendering: yes" and references to Nvidia as the vendor the the GLX client. I've tried installing the Nvidia drivers via apt (the Debian package manager), "envy" - a script for installing nvidia and ATI drivers on Ubuntu and by Nvidia's own script, recompiling and linking Producer/OSG each time, all with the same result. I've tried running with the dual core technology turned off (BIOS) and with a non SMP kernel. And now I've run out of ideas... any suggestions please?
