I’m on Ubuntu Gnome 15.04, using the suggested “additional drivers”. I have a 24" main screen with a secondary 10" screen.
Within NVIDIA X Server Settings, in the Powermizer tab, 3 performance levels are shown:
- 0 -> clocks 50 MHz 270 MHz and 101 MHz for Graphics, Memory and Processor respectively
- 1 -> clocks 405 MHz 648 MHz and 810 MHz
- 2 -> clocks 795 MHz 4008 MHz and 1590 MHz
Powermizer let me to chose between three options under the “Preferred Mode” select:
- Prefer Maximum Performance
Auto is selected. And “Current Mode” shows it is in Adaptive mode.
My problem is that, whenever the secondary monitor is enabled, clocks are always at performance level 2 at desktop, while doing nothing.
If the secondary monitor is disabled (either in “NVIDIA X Server Settings” or in “Ubuntu -> Settings -> Screen Display”) everything works as intended and clocks adapts to load.
In Windows, I solved this issue with a software called NvidiaInspector which has a “Multi Display Power Saver” tool that forces iddle clocks with dual monitors.
So in conclusion, my question is:
is there anything I can do in linux to have that feature from Nvidia Inspector?
