@anon11595408 unfortunately neither of these worked for me. I even went down the rat hole of renaming “.desktop” files in /etc/xdg/autostart so they would not start and that did not give wanted results either.
Did you save your session before shutting down your computer ?
It happened to me before, I had the same elements loaded twice, ones with the saved session, seconds with the autostart. I had to delete the files in ~/.cache/sessions and uncheck the save option in the shutdown dialog.
I don’t intentionally save the session before shutdown, don’t have a~/cache/sessions folder and cannot find a saved session. Unlike XFCE I don’t think Openbox can (or does) save a session. I’ve looked and looked.
just for reference, i have the doubled icons issue too on manjaro. it started recently (1 month max). so it’s really a thing. Not all icons are doubled (I assume not all allow two instances?).
and we should stay on topic… it is about xfce4 tray not tint2 … it will confuse others joining the thread with the same issue as the initial poster.
What happens when you right-click on the existing panel? You should get a menu like this: Panel → Panel Preferences. From there, click the plus sign near the top-right corner; hovering tool-tip should say Add a new panel.
