Hello, I am very much a linux newbie, so please bear with me.
I am trying to get an application at work to run on a new laptop. This application is very OpenGL 3D graphics intensive. While the 3D images render, they are unusably slow. Even a simple program like glxgears is slow and jerky. Glxgears is running at 3.5 FPS and is taking 100% of a CPU. I have a somewhat bizarre configuration in that I am using a cloned image of a previous computer on newer hardware. Sadly, I can’t get around this because of the complications in the software installation.
Hardware: HP Elitebook 8770w with a Quadro K3000M graphics card.
uname -r = 2.6.18-128.el5xen
uname -i = x86_64
XServer = 7.1
It seems like the nVidia drivers are installed correctly:
glxinfo | grep -i render
direct rendering: Yes
OpenGL renderer string: Quadro K3000M/PCIe/SSE2
The only troubling thing I have found (aside from it not working) is when I
dmesg | grep -i nvid, I get
nvidia: module license ‘NVIDIA’ taints kernal
However, it looks like the module loads right after that.
From some google searches, it looks like this message might be spurious?

Thanks. I looked into this. It seems like the original image also throws this error as well. My understanding is that this error can potentially make rendering graphics unstable, but doesn’t stop the GPU from being used.
I’m wondering (the more I google) whether or not something is not set up correctly since this is using a Xen Kernel. Xen has VGA forwarding turned on, and for all intents and purposes it looks like the guest os can completely see the graphics card. In fact, the Xen software graphics driver isn’t even an option. Accept for 3D graphics, everything else seems fine from a graphics standpoint.
