just adding that in case B sometimes the blank screen got back when cosing the switched user session.
I solved it:
1. changing the above conf codes in xorg.conf from Option "AGPMode" "8" to Option "AGPMode" 1"
2. completely removing the gnome-screensaver package as suggested here https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/546578
I don't know if these info are useful for debugging action. Hope so. cheers
