I was tired of having to configure manually the disposition of my monitors when I plugged them in.
So I decided to write this script that define custom behaviour when monitor are plugged in
You might want to adapt the script to your needs ./usr/local/bin/monitor-hotplug.sh
I was inspired by http://stackoverflow.com/questions/5469828/how-to-create-a-callback-for-monitor-plugged-on-an-intel-graphics
git clone https://github.com/codingtony/udev-monitor-hotplug.git
sudo chmod +x ./install.sh
sudo ./install.sh
sudo journalctl -f
OR
sudo service udev stop
sudo udevd --debug 2>&1 | tee /tmp/udev.log
check what's happening when you plug/unplug your monitor
I'm not responsible of the effect of this script on your computer
Feel free to do whatever you want with it :-)
