I’m using Linux Mint MATE. I would like to launch a gui application without recognized by my eyes. I tried the following code which launches the application and moves it to another workspace with 

wmctrl
right after the launch but that didn’t work.

some_app_with_gui &
wmctrl -r title -t 1 #move window to another workspace (Say I'm in workspace 0 now)

As indicated here, the reason is that 

wmctrl
is executed before 
some_app_with_gui
‘s window appers. So the solution would be

some_app_with_gui &
sleep 0.8
wmctrl -r title -t 1 #move window to another workspace (Say I'm in workspace 0 now)

and this actually works.

With this solution, however, the window is recognized by my eyes for a moment (0.1 seconds or so). This is truly annoying and I’d like to avoid it.

Are there any solutions? It doesn’t necessarily have to use 

wmctrl
. Any other commands will be ok. And please note I don’t access the window, i.e. the application is launched by a script and closed by the scripts, so completely hiding the window is ok.

How this question is different from ones with similar titles is

  • that only one machine is involved (not SSH-related)

  • and that I would like to launch gui application on a machine with a desktop environment without gui.
