[Pkg-acpi-devel] Bug#555110: acpi-support: lid events affect external monitor as well as laptop panel

Package: acpi-support
Version: 0.123-1
Severity: normal

/etc/acpi/lid.sh appears to treat open and close lid events by calling
screensaver routines.
But the screensaver routines affect all monitors connected, including
my external monitor.

So after I close the lid, both my external monitor and panel go off.
And when I move the mouse, they both come back on.
But I don't  want the panel on when the lid is closed. It gets hot and
burns up energy.

lid.sh should affect only the panel and be independent of the
screensaver routines.

I have modified mine by adding "xrandr --output LVDS --off" and
"xrandr --output LVDS --auto" after the two "export DISPLAY=" lines
and removing the screensaver stuff there.

But this only works when LVDS is the panel name. Other drivers may
have different names for the panel?
