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
lsmod | grep -i nvid
nvidia 94445748 30
i2c_core 56129 2 12c_ec,nvidia
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?
