All the app links in xfce4's "[Dom0] Session and Startup" window under the tab "Application Autostart" (see screenshot) cannot be Edit-ed which is probably because they reside in /etc/xdg/autostart/ as *.desktop files; another way to see what command they execute is looking at the tooltip shown by hovering the mouse on them.
I needed to see what's the command for that blue "Q" in systray(aka Notification Area) because it went away after some dialog popped up. The answer is: it's one of the "Domains Tray" items(there are two) whose command is: $ python3 -mqui.tray.domains & (added the "&" to let it go into background for when running it inside the dom0 terminal; without the "&", Ctrl+Z then "$ bg" also works) This post was supposed to be a question but before posting it I've figured it out, but I'm still posting it just in case it might be useful to someone or even future me. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
