In fact, preloading an incorrect version of the library will only give you more problems (e.g. you may lose hw acceleration or even crash X). Run glxinfo and check whether proper driver is enabled - it should be in the 'renderer' string, including whether hw acceleration is on or not. The error above looks like an incorrectly installed graphic driver. I don't know what Ubuntu ships, but you need the AMD 'fglrx' driver, including the matching kernel module for OSG to work properly. Make sure to install it correctly and actually restart the machine after building/installing the kernel module. The X11 error means that the application is trying to do something that isn't supported by the driver. Regards, Jan
