NVIDIA Driver stopped working. No 3D acceleration.
My problem started with the following post.
I ended up tracing the issue back to openGL that disappeared during an update and the nvidia driver had broken. The only remaining issue is that the 3D acceleration on the NVIDIA (GeForce 8600 GT) card will not activate.
It appears to be the following issue:
Which I have done many times now. I am now on the nvidia-173 driver as that one seems to be working the best. Even the nvidia-settings is having trouble and crashes when I try to look at the OPENGL/GLX information.
I have found many instances of jockey showing that the driver is "active but not in use" which is what I am seeing. The problem is that the 3D acceleration is not working and the issue seems to be the driver.
