XGL DPMS support and XV acceleration

[Ioannis Nousias]

sorry if this is a re-occurring subject.

Does Xgl support DPMS?
Running "xset -q" on my xgl build reports:

DPMS (Energy Star):
  Display is not capable of DPMS

is this a configuration problem or Xgl is indeed not capable of DPMS?

I've read somewhere on the list (I can't find it now) that hardware 
overlay is not used in Xgl. If I'm not mistaken, isn't "xv" (X-Video) 
the interface for hardware overlay? What does the xgl server option 
"-accel xv" do?

using "mplayer -vo xv" on my nvidia equipped laptop runs extremely slow. 
I've tried these xgl options:
"-accel xv"
"-accel xv:pbuffer"   and
"-accel xv:fbo"
and I get the same results.

"mplayer -vo gl2" is fine (although not as good as using xv on a normal 
Xorg xserver)

regards,
Ioannis

PS: this is the configure options I use for building xgl:
PKG_CONFIG_PATH=/opt/Xgl/lib/pkgconfig ./autogen.sh --enable-xgl 
--disable-xorg --disable-xprint --enable-glx --enable-dri 
--with-mesa-source=/tmp/mesa --with-release-snap=1 --disable-dmx 
--disable-xvfb --disable-xnest --enable-xglx --enable-xkb 
--disable-kdriveserver --prefix=/opt/Xgl

my xorg.conf file has Option "DPMS" "on" both in Device and Monitor. 
DPMS works fine in normal Xorg xserver
