My xorg.conf uses vesa driver.

It doesn't have DPMS configured specifically, but the default is to enable 
the extension.

This is with xf86-video-vesa-1.3.0 with xorg-server-

"xset dpms force standby" and "xset dpms force suspend" and "xset dpms 
force off" all turn on the default X screensaver.

"xset q" shows:

DPMS (Energy Star):
  Standby: 1200    Suspend: 1800    Off: 2400
  DPMS is Enabled
  Monitor is On

My Xorg.0.log has:

(II) VESA(0): DPMS capabilities: StandBy Suspend; RGB/Color Display

My display is:
(--) PCI:*(1:5:0) ATI Technologies Inc ATI Radeon Xpress 1200 Series rev 
0, Mem 

pci bus 0x0001 cardnum 0x05 function 0x00: vendor 0x1002 device 0x791f
 ATI Technologies Inc ATI Radeon Xpress 1200 Series

Anyway to turn off the physical display when using vesa?

Or please point me to documentation on this.
