Bug#625541: nvidia-glx: Screen blacking out as a result of mouse movement, scrolling & clicks

[Michelle Pierce]

Package: nvidia-glx
Version: 195.36.31-6
Severity: normal

I have a dual monitor configuration, the right hand screen (and occasionaly the left) is constantly blacking out with any kind of mouse movement or scrolling. Most of the time it comes back after a second or two but occasionaly the screen blacks out permanently and I have to log out to restore it.
I've tried to disable powermizer by adding this line to /etc/modprobe.d/nvidia-kernel-common.conf:
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
This has had no obvious effect.
