Is there a command line tool that allows you to adjust the settings for a running X session?
For example, the equivalent for pulseaudio would be the
pacmd command line utility which allows you to add/edit/delete audio devices.
I'm asking because I've got a setup using Xdmx connecting several networked screens together, and I would like to know if theres a way to add and remove screens without too much effort
Thanks in advance.
