My T30 blanks the display, but the backlight is still on. I have only been able to turn it off with the VGA DPMS stuff, not Xorg or XFree86. For the record, my system is Beta-7 dated Oct. 12, so it's pretty close. This may be a bios configuration issue or some difference between the T30 and the T40 even though both use Radeons. -- R.
