I have two monitors that are both connected to my computer. I want to have them un-mirrored, and it works fine in Cinnamon (after tweaking some settings), but I can't find a way to do this in a custom desktop environment with Compiz.

Here is the script that starts my DE:

docky &

I'm running Linux Mint 17 (Based on Ubuntu 14.04 Trusty Tahr).


I finally figured it out: All I had to do was to add the line xrandr --output DVI-0 --mode 1280x1024 --output DVI-1 --mode 1024x768 --left-of DVI-0 to the beginning of my DE script.

To find the values for the --output options, just type xrandr. Here's the output of xrandr on my machine right now:

Screen 0: minimum 320 x 200, current 2304 x 1024, maximum 8192 x 8192
DVI-0 connected primary 1280x1024+1024+0 (normal left inverted right x axis y axis) 376mm x 301mm
   1280x1024      60.0*+   75.0  
   1152x864       75.0  
   1024x768       75.1     60.0  
   800x600        75.0     60.3  
   640x480        75.0     60.0  
   720x400        70.1  
S-video disconnected (normal left inverted right x axis y axis)
DVI-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768       60.0* 
   800x600        60.3     56.2
