Multi Monitor

If you have a multi-monitor setup, edit your copy of config.ini with the correct values for your particular setup. Like this:

# Multi Monitor Configuration                                                         
enable_multi_monitor  = true                                                          
enable_xrandr         = true                                                          
current_monitor_setup = [monitor_3]

The default example is configured for a specific setup with 3 monitors, with the tablet being the rightmost, like this:

   [Left:2560x1440] - [Middle:1920x1080] - [Right:1920x1080](TABLET)

Take a look to the 3 of the config.ini file, where diffeente multi-monitor configurations are defined:
