Here is an update with the problem that I had with my nvidia Quadro 900 XGL running chimera and freezing the system. It was a hardware problem with the card (it seems that the fan was not working and something got burned ??). At the beginning only OpenGL applications such as Chimers or Google Earth were causing trouble freezing the system. Eventually display problems appeared all the time regardless of the application. I replaced the card (for an ATI Radeon 9550) and now everything seem to work fine Thanks for the previous suggestions Regards Hernando . Thomas Goddard wrote:
Hi Hernando,
You might find a solution by changing the Nvidia driver performance and quality settings. Right click on the desktop, select Properties, Settings, Advanced, Quadro 900 XGL to find these. Generally you would want to change the settings to lower performance. The bugs seem to usually be in the graphics driver optimizations, and perhaps your case is related to having multiple processors.
