My new laptop has the ability to support up to 3 concurrent displays.  I
have found that this is actually a problem when I try to use it in my
home office, where the (closed) laptop is placed into a docking station
that is connected to two external displays.

The default X behavior is to use both external displays *and* the built-
in display.  Of course, the KDM login fields end up on the invisible
built-in display.

I can't use a static X configuration to work around this problem,
because there are plenty of times that I'll want to use the built-in
display.  I need to do this:

   if /usr/bin/grep -q closed /proc/acpi/button/lid/LID/state; then
       NUM_DISPLAYS=`/usr/bin/grep ^connected$
/sys/class/drm/card0-*/status | /usr/bin/wc -l`
       [ $NUM_DISPLAYS -gt 1 ] && /usr/bin/xrandr --output LVDS1 --off
   fi

(This disables the built-in display when the laptop is closed *and*
there is at least one external display connected.)

In theory I should be able to add this to /etc/kde/kdm/Xsetup, but it
seems that kdm_greet is already running when this script is executed, so
the theme geometry gets all messed up.  (My external displays do not
have the same resolution as the built-in display.)

For now, I've replaced /usr/libexec/kde4/kdm_greet with a wrapper script
that does the xrandr stuff and then runs the actual program.  This is
obviously fragile, however.

Can anyone think of a better way to do this?

Thanks!


I currently install the following as /etc/X11/xinit/xinitrc.d/nolvds.sh

#!/bin/sh
# 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


Of course just after sending this I realized that this is what runs *after* login as well. My work around to get the login window onto the proper screen has been to set GreeterScreen as needed in /etc/kde/kdm/kdmrc.
