I'm trying to use openbox to customize my raspberry pi 3. Basically, what I want to do is start an openbox session on boot up and have openbox autostart a GUI application. This is what I have so far

in ~/.config/lxsession/LXDE-pi/autostart

I commented out the first 3 lines:

#@lxpanel --profile LXDE-pi
#@pcmanfm --desktop --profile LXDE-pi
#@xscreensaver -no-splash

and added this line:

@openbox-session

This causes openbox to start when I boot up my system. I see a black screen

Following this guide: http://openbox.org/wiki/Help:Autostart It says that

"When you log in with the "Openbox" session type, or launch Openbox with the openbox-session command, the environment script will be executed to set up your environment, and the autostart script can launch any applications you want to run at startup."

so, I edited the autostart file in ~/.config/openbox/autostart in my pi user. (I also tried editing the global file) I put this in the file:

/home/pi/mystartupprogram

On first reboot it worked my GUI starts up which is great but...next reboot I'm back to black screen and I see part of my GUI in the top left corner and all the rest is black.

    Hi did you ever solve this? I'm researching the most light-weight possible way to create a kiosk that will show a web page with possible image transitions (dakboard.com specifically). I would like to use a Pi Zero W so it's gotta be REALLY light. I wish someone had an opengl or framebuffer driven browser that could run from the GPU from the terminal (graphical - not lynx) – Adam Plocher May 19 '17 at 06:57

This is the simple answer: sudo update-alternatives --config x-session-manager One can just run this and select the openbox-session then the next restart will get you the openbox window manager. No need for hacking files etc.

  • Can you edit and expand upon your answer, else it may be deleted. Stack Exchange is looking for comprehensive answers. – Greenonline Jan 14 '21 at 17:34
  • This answer doesn't need any more explaination this is the best way to switch to an alternative window manager on a raspberry pi – CoderChris Jan 20 '21 at 12:40
  • This is the right answer: if the OP will ever want to go back to lxsession, or have to reconfigure a system after reinstalling it, doing manual changes in a bunch of config files will take lots of time. – Dmitry Grigoryev Jan 25 '21 at 08:38
  • Instead of rebooting, restarting the display manager should be sufficient. sudo systemctl restart display-manager.service – sshow Oct 05 '21 at 08:38

I had the same problem. I post it for any future googlers.

  1. Disable Desktop autologin

    Run sudo raspi-config and navigate to 3 Boot Options / B1 Desktop / Cliand choose B2 Console Autologin

  2. Run startx in rc.local

    Open rc.local with sudo nano /etc/rc.local. At the end, before exit 0 add startx &

  3. Configure xinitrc

    sudo nano /etc/X11/xinit/xinitrc

    Comment this line

    . /etc/X11/xsession

    Add this line to start openbox

    exec openbox-session

  4. Run your programs with autostart

    sudo nano /etc/xdg/openbox/autostart

    Add your commands

    /path/to/program &

    Important: End all commands with &

Voilà, you have now an Raspberry Pi that automatically boots to Openbox and autostarts your applications

  • Worked perfect, but I've used the following part in ~/.bash_profile: [[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && startx (instead of the rc.local part) – Michael B. May 23 '22 at 08:35

I found this to be useful

install the rpi lite version then:
sudo apt install lightdm openbox
lightdm = login manager, just use raspi-config to select autologin gui
openbox = gui to run your app

you can use a tty for command line to setup your app to auto start:
example:
mkdir ~/.config/autostart
nano ~/.config/autostart/my_app.desktop

in nano:
[Desktop Entry]
Type=Application
Exec=/path/to/my/app <-best to use full path ex: /home/pi/bin/my_app
