Is there a way to prevent this?

So, I would suggest to explicitly declare theses workspaces. In order to start on workspace 1 for the first monitor and on workspace 6 for the second one (where the name of the monitor/output depends on your configuration, like LVDS0 and LVDS1): workspace 1 output LVDS0 workspace 6 output LVDS1 ... workspace 9:mail output LVDS1Thu, 21 Mar 2013 15:41:19 +0000https://faq.i3wm.org/question/1457/assign-program-to-specific-workspace-on-specific-output/?answer=1458#post-id-1458https://faq.i3wm.org/question/1457/assign-program-to-specific-workspace-on-specific-output/?comment=1459#comment-1459Thanks, that's working!Thu, 21 Mar 2013 16:33:32 +0000https://faq.i3wm.org/question/1457/assign-program-to-specific-workspace-on-specific-output/?comment=1459#comment-1459
