Display calibration profile is deactivated after screensaver kicks in

[Andreas Siegert]

I am running a Lenovo T520 with an Nvidia proprietary driver 310.19 in dualscreen mode using 12.04 64bit.
I have display profiles loaded for both screens.

The profile of the primary screen is disabled (but still loaded) after xscreensaver has blanked the screen.
I need to run dispwin -L after authentication to get the profile activated again.

The same for me, profile on the second screen is deactivated when xscreensaver loads blank screen.
