Monitor energy saving not working with nvidia driver in leap 42.1

I’m using the default kernel in leap 42.1 with nvidia driver version 352.55 from the official repository.
I have 2 monitors, eizo ev2450. They do not switch off when Screen Energy Saving is turned on, they just turn black.
It works with nouveau driver but it makes the computer lock up.
Have anyone else experienced this?

This was a nvidia driver bug which has been fixed in version 352.63
It’s not yet in the repository but I did a manual install and the problem is now fixed

Its specific to DP.
Perhaps this thread could be moved to hardware.

The new version of the nvidia driver is actually in the nvidia repository
