When switching to power save mode nvidia disables the graphics card multiple display support.
It does not enable it back when switching to performance mode. This was done by creating a file in /lib/modprobe.d/nvidia-kms.conf and setting modeset to 1.
We can revert this change by changing the modeset to 0 or commenting this line. After rebooting, the external display works again.
