1. In the docking station with monitor connected
2. Without the docking station just with the display
I had problems with this setup when suspending / waking up in Kubuntu 12.04. When I suspend without docking station connected and wake up without docking station connected, everything goes well. But when I wake up in the docking station it has problems with recognizing the monitor. All I can do is to restart the Xserver. It means it is useless to suspend.
So I wrote the script to detect whether the laptop is in docking station or not while it is wakeing up.
Create new file:
$ sudo nano /etc/pm/sleep.d/90_switch_display
With this content:
case "$1" in
if xrandr | grep -q -e "HDMI2 connected"; then
xrandr --output LVDS1 --off
xrandr --output HDMI2 --auto --primary
xrandr --output HDMI2 --off
xrandr --output LVDS1 --auto --primary
Than save it and set it executable:
$ sudo chmod 755 /etc/pm/sleep.d/90_switch_display
And that's it. Waking up behaves well ;-)
