DPMS Standby not working with NVS 810 using driver 375.26 via mini-DP to DVI

Good News. I can safely say that as of nvidia driver 375.66 on Fedora 25 with XFCE I am now able to get my monitors to properly go into a DPMS standby mode. This works with both XScreensaver and “sudo xset dpms force off”, and was done on a NVS 810. A future driver update may cause it to break again, but for now it is working.

Hi developeralgo222,
This most likely looks window/display manager issue with Unity, Gnome or KDE whatever desktop environment you are running. I advice report this issue to os vendor i.e Canonical to check does the window/display manager supports that much of displays.
