Configure

Create a Auto Start File

mkdir /home/pi/.config/autostart
nano /home/pi/.config/autostart/mumble.desktop

Configure Auto Start File

Fill out
Name: Mumble
Exec: /usr/bin/mumble mumble://TestUser@server.com:23840/Open%20Talk/Subchannel%20A/?version=1.2.0

[Desktop Entry]
Type=Application
Name=99-Mumble
Exec=/usr/bin/mumble mumble://TestUser@server.com:23840/Open%20Talk/Subchannel%20A/?version=1.2.0

Now every time you login the application above will auto start

Startup Order

The Name section is in alphabetical order. Name the application 00-Firefox 99-Mumble etc.

Adding Delay

Sometimes configuring the application to start in a certain order is just not good enough.
For example Mumble kept appearing on top of firefox.

Edit the *.desktop file

nano /home/user/.config/autostart/mumble.desktop

Add the following line to the end of the file.

X-GNOME-Autostart-Delay=33

The numerals represent how many seconds the delay will be
