While playing with the i3 tiling manager tool I had this issue where the workspace number two would appear on my primary screen and the workspace number one would appear on my second monitor.

The solution for that was to create a ~/.xprofile file containing my randr configuration:

xrandr --output VGA-0 --mode 1920x1080 --pos 1920x0 --rotate normal --output DVI-D-0 --off --output HDMI-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal

Now these settings are executed at startup and i3 is starting the workspaces on the right monitors. To generate the xrandr command I used the tool “arandr” to set the settings and used the functionality “save as” to export the configuration command.

By the way, i3 is awesome!
