I'm not sure if it'll have any ill effects, but my problem went away by commenting out all lines in the /etc/acpi/events/videobtn file and then rstarting acpid. I assume this causes the acpid to ignore the event that is triggering the backlight to come back on when the lid is still closed.
The backlight now stays off unless the lid is opened or an actual button is pressed. -- closed Laptop Lid to reliably keep Backlight off https://bugs.launchpad.net/bugs/41994 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
