Thanks for the clarification. When you said you first noticed the problem in the 195 driver, I thought that you meant that you hadn't noticed it in driver version before that.

When you say that `xset force dpms off` does the same thing once it starts happening, do you mean that turning DPMS off when the machine has not been on for a very long time works normally, but after it has been on for a while, it will fail?

A quick experiment that might point to whether this issue exists in the NVIDIA driver is to run your X server with the vesa driver, and try to induce the problem.
