Launching and mapping applications to specific virtual desktops

Hello all,

I searched the topics maybe wrong but I would like to know if or how I can make it so that certain applications are launched on /moved to certain virtual desktops?

xfce: 4.16
OS: Linux 5.4.112-1-MANJARO

Thanks in advance for any advice.

Hello and welcome.
You can use devilspie or the newer gdevilspie. See: this thread for a discussion.

This looks very promissing! I already have my .ds script for testing purposes ready:

(if
    (is (application_name) "Signal")
    (begin
        (set_workspace 1)
    )
)
(if
    (is (application_name) "Vivaldi")
    (begin
        (set_workspace 2)
    )
)
(if
    (is (application_name) "Thunar")
    (begin
        (set_workspace 3)
    )
)
(if
    (is (application_name) "noson")
    (begin
        (set_workspace 4)
    )
)
(if
    (is (application_name) "VirtualBox")
    (begin
        (set_workspace 4)
    )
)
(if
    (is (application_name) "VirtualBoxVM")
    (begin
        (set_workspace 3)
    )
)

I already created the ~/.devilspie/ directory in my home as well as a .ds file in there.

Could you post yours as an example? Of course only if you use it for yourself. Do I need to setup devilspie to autostart via systemctl? How would you do it to be executed best when my login accurs?

Thanks for your great help!

[update] I get the following error messages which I try to figure out

When I've used it, I just place an entry in Application Autostart (Settings Manager > Session and Startup > Application Autostart). If you want, you could create a user-based systemd service for this as well.

I believe you are allowed only one "if" statement in a file with original devlispie. You will need to create multiple .ds files - one for each application. With devlispie2, I think it allows multiple directives in one file, but it uses lua-styled scrtipting language instead.

Re: Launching and mapping applications to specific virtual desktops

Does gdevilspie still work? It did not the last time I tried (Debian 10). I should give it a whirl on our MX-21 alpha.

MX-23 (based on Debian Stable) with our flagship Xfce 4.18.

Thank you for your hint about the Autostart. Regarding the "if" statement, it seems not necessaryI. I found these tutorials which helped me learn how to write .ds correctly.

https://wiki.gnome.org/Projects/DevilsPie

Solved! Thank you!
