Ubuntu – Put external monitor on the left

14.04displaymultiple-monitorsunity

On my laptop with 14.04, I want to use an external monitor. I want to put my external monitor on the left side but ubuntu seems to logically put it on the right side. I tried to organize the display placements, but when I drag built in monitor to the right all my desktop icons moves to the external monitor. How can I solve this issue.

  • The screen icons in the system settings can actually be dragged, so you can place the green Samsung on the left. Alternatively, you can use this command:

    xrandr --output HDMI1 --mode 1024x768 --pos 0x0 --rotate normal \
           --output LVDS1 --mode 1366x768 --pos 1024x0 --rotate normal
    

    I use this command (with different outputs of course) to position my screen, VGA to the left, internal monitor to the right, on graphical login.

    Alternativelly, you can look into lxrandr program, which does exactly same job as Ubuntu's settings, but may be a little less confusing.
