I should note that closing the lid does turn off the backlight, and opening the lid does turn the backlight back on.
gnome-screensaver and g-p-m however do not turn off the backlight, nor does g-p-m make the system sleep after the set time out. I do not know if the sleep problem is related but I have been told the backlight issue is because of the lid state being close. -- cat /proc/acpi/button/lid/LID/state returns closed https://launchpad.net/bugs/78163 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
