That is no good, as any mouse jitter (or external keyboard use) will
wake the screen. It happens frequently on my HP Laptop.
I use xrandr --output LVDS --off
I haven't hooked this up to the lid switch. The BIOS emits "video
button" type events when you shut the lid on this machine, so it might
need a short timer to ensure the call to shut the display off happens
I wonder actually.. could we use the equivalent of the above xrandr call
inside the driver to shut the display off when appropriate? I appreciate
in some cases, closing the lid means you just want to power down the
back-light and LVDS panel. In others (with external monitor and perhaps
TV hooked up), you might want the LVDS output completely dissociated
from the crtc.
I do know that the BIOS in this laptop (Don't buy HP), is really buggy
with respect to lid settings, and non-obedience of the finer-grained
_DOS control. (Its either ON in bios fiddles behind your back mode / OFF
_completely_, where it de-programs the GPIO interrupts used to monitor
(A DSDT hack fixed the above, but not the "fiddles behind your back when
plugging / unplugging AC. That's in SMI code, and I've not got far
enough into trying to dump the BIOS update to fix that yet).
