DisplayPort on NVIDIA Corporation graphics - sleep issues

I have a NVIDIA Corporation GeForce GTX 970 video card, running a fully updated system.   Kernel 4.1.2-2-ARCH and nvidia drivers version: 352.21.  I am using KDE  Powerdevil 5.3.2-1 (plasma)

I am having this problem that my screen wont go to sleep using  the KDE Energy Saving Module.   

I tick on Screen energy savings but when   the screen turns off I get Displayport No Signal and I have to reboot/ctrl-alt-backspace to a new session.   I have taken a look at the xorg.log and journactl but I can't find anything relating to the displayport in them.

Any help and or tips would be greatly appreciated.

Re: DisplayPort on NVIDIA Corporation graphics - sleep issues

I have a somewhat similar issue. I'm running a dual monitor setup on a single gtx770. 1 in 3 boots will give me mirrored monitors, and switching them back to separate will throw the entire system into disarray with screen tearing. I filled a bug report on qt5-graphicaleffects here in arch's bug reports. I worked around it by removing qt5-graphicaleffects and kscreen (pacman -Rdd).
YMMV

edit- keep libkscreen. Don't remove anything BUT qt5-graphicaleffects and kscreen

Re: DisplayPort on NVIDIA Corporation graphics - sleep issues

Thanks for the tip Buddlespit.  I now have this fixed...sort of.  My screen enters sleep mode but I get a plasma crash as soon as I wake the monitor up.
