Public bug reported: Binary package hint: xorg
Currently on lucid beta, also experienced this on karmic for sure and possibly earlier. Gnome's screensaver is off, and power management is set to turn off the monitor after ten minutes. "xset dpms force off" turns off the screen and backlight for approximately a minute, before the display turns back on. Seemingly randomly, the 10 minute timer only blanks the screen rather than also turning off the backlight. This occurs under metacity and compiz. This is a single lcd on an intel-video laptop; I also see seemingly identical symptom on two desktops with nvidia video cards running dual- head desktops under both metacity and compiz (proprietary driver, under karmic and jaunty), and on a singleheaded radeon 9250 (open driver, karmic), (1) where the display's may be sit for days without turning off the backlight despite the power options being configured, (2) "xset dpms force off" turning the backlight off, and then back on to a full display after a minute or so.
