I'm running Centos 6.3 on a Dell laptop, I'm not running a graphical desktop - just text mode. When I shut the laptop lid the display remains active with the backlight on, whereas I'm expecting it should switch off and back on when I open the lid.
ACPI events are being received and acpid is running.
What command can switch the display & backlight off and on? Is there an acpi action script that can do the job for me?
