Deactivating LVDS display when laptop lid is closed

[Orion Poplawski]

Apparently[1] it is up to the desktop environment now to deactivate the LVDS 
display if the laptop lid is closed at boot (or whenever?).  I now have 
several F13 laptops in docks with external monitors that boot with the lid 
closed, but kdm_greet puts the login panel on the closed LVDS display (see 
bug[2]).  I've also filed a Fedora bug for similar stuff here [3].  I don't 
know how gdm behaves.

Any other comments/help?  I tried doing:

# Disable LVDS if another output is up
if xrandr --current | grep -qE '^(DVI|VGA).* connected'
then
    lvds=$(xrandr --current | awk '$1 ~ /LVDS/ { print $1 }')
    xrandr --output $lvds --off
fi

in /etc/kde/kdm/Xsetup, but kdm_greet appears to get stuck in an infinite loop 
and I only see the small round black spinner cursor, never the login panel.

I thought about posting to the Fedora KDE list, but I'd like to get some wider 
input.
