Public bug reported:
Binary package hint: xserver-xorg-video-intel
On my Lenovo X200 notebook (GM45 graphics), the backlight sometimes (not
always -- maybe one fifth of the time or so) stays off after a
suspend/resume cycle. In other words, the system resumes properly
except that the backlight does not turn on (screen contents are dimly
visible, unlocking the screen, typing, etc work fine). Doing "xset dpms
force on" or "xset dpms force off" or pressing any of the brightness
function keys has no effect.
