Dual monitor setup in Xfce

If you have a system with two or more displays/monitors and are using a Linux XFce desktop environment then there are at least three methods for dual monitor setup in Xfce:

1. Use the built-in Xfce Settings -> Display configuration utility.

2. use the Resize and Rotate tool for X window system (aka xrandr). Read more.

3. use the Xfce Settings Editor

If you choose to use the last method then follow these steps:

1. open the Settings -> Settings Editor

2. on the left list (Channel) choose the displaychannel; on the right side you are going to see your current monitor setup

3. identify the leftmost display and make sure you set Position.X=0

4. identify the next rightwards monitor and set its Position.X value equal to the previous monitor Position.Resolution width value (eg. 1440x900 means width=1440 and height=900)

5. repeat the steps 3-4 for the rest of the rightwards monitors

6. close the Settings Editor, logout your current Xfce session then login again.

That's all folks!
