WebGL and GPU acceleration blocked in Firefox

English Applications
1

In attempt to improve poor Firefox 11.0 performance (4-5 times slower than Chrome 18 for same url retrieval), I installed the 4.2.0 Nvidia 295.40 driver for my Nvidia GeForce GTX 460 SE video card using the latest lnvhw installer tool. When I go to Firefox/Help/Troubleshooting Information/Graphics, it reports that
(1) “WebGL Renderer: Blocked for your graphics card because of unresolved driver issues” and
(2) “GPU Accelerated Windows:0. Blocked for your graphics driver version. Try updating your graphics driver to version <Anything with EXT_texture_from_pixmap support> or newer.”

How do I fix this?

My environment is 64-bit:
Opensuse 11.4
Kernel 2.6.37.6
Nvidia GeForce GTX 460 SE video card

So, as the author of lnvhw, I have install the latest nVIDIA driver. When I look at the same location, here is what I see:

Graphics:
      
Adapter Description:     NVIDIA Corporation -- GeForce GTX 560/PCIe/SSE2
Driver Version:          4.2.0 NVIDIA 295.40
WebGL Renderer:          NVIDIA Corporation -- GeForce GTX 560/PCIe/SSE2 -- 4.2.0 NVIDIA 295.40
GPU Accelerated Windows: 0

If you open up a terminal session and run this, what do you see:

nvidia-smi -q | less

Here are the first few lines on my computer:

Now I am running kernel 3.3.1 right now and loaded it using SAKC and not sure if that really matters or not.

Thank You,

James, thank you for your reply. Since posting, things have changed. Firefox/Help/Troubleshooting information/Graphics now seems to look ok:

Here’s the output from nvidia-smi -q

The things that have changed are that some updates came down and I’ve booted the system a couple of times. I’m still on the hunt as to why Firefox is so slow.

Well, let us know if we can help again. Sorry to get back so late, but I was out of town the last couple of days.

Thank You,
