Re: Nvidia 8500 secondary screen tearing
For starters you need to read the forums on how to post a bug report. Now if what you are referring to as a "bug" is tearing on a second monitor (whereas the other works fine), then this is not a bug in the NVIDIA driver, but a limitation of X.org itself.
In `nvidia-settings`, Go to "X Server XVideo Settings", and at the bottom you will see both your monitors and an option to "Sync to this display device". Simply sync to the monitor you are watching. You can only sync on one screen at a time. If both your monitors have the same refresh rate you shouldnt see tearing on either.
