I'm using fujitsu LH531 Laptop with ubuntu 12.04, and with secondary 1440x900 monitor attached to the VGA, confirmed by xrandr command.

The problem is, i want to run a program (vlc) to the second monitor, but can't find a way for that.

I've tried, DISPLAY=:0.1 vlc and a jumbled screen. Trying DISPLAY=:0.1 firefox, got error cannot open display 0.1.

The current condition is that the dual monitor is worked as 2 separated screen (e.g screen a showing firefox, screen b libreoffice)

Can anyone please help on this? the main goal is, how to run vlc (program) to specific monitor.

Below is the output of xrandr.
