Xorg.0.log
X screen blanks after timeout, but backlight remains on forever. "xset dpms
force off" has no effect. "vbetool dpms off" does turn off the backlight. Using
nvidia proprietary driver, "xset dpms force off" turns off backlight but then
has other issues (

)
Curiously, and possibly related, "xset s activate" (via ssh and/or using sleep
1) has no effect. It does not blank the screen.
Possibly related, from Xorg.0.log:
