Xorg log on startup

Hi,

I get a reproducible freeze on my system when the energy management
is turned on.

How to reproduce: Boot the sytem, wait until energy management kicks in.

Symptoms: Screen is black, mouse pointer still visible, unable to do
anything except switch to a text-base virtual console.  Login works well there.
Only way to reset the graphics that I have found is to reboot.

Workaround: "xset -dpms"

Output of xset -q:
