You may need to create the auotstart directory if not present It requires your sktop file(s) to be located here for pi user /home/pi/.config/autostart/ or for other user /home//.config/autostart/ The traditional method also has a user based option. This method does not use an autostart file. Note that autostart here is a directory and not a file. You can use this directory to start apps or scripts which will apply to all users. This means if there is an error or the program terminates then you will not be able to see what happened as the terminal window will flash by too quickly.īeginning with the Dec 2020 release, Raspberry Pi OS now uses the /etc/xdg/autostart directory to start some background apps for printer etc. If the script or command exits to the command line for any reason then the terminal is immediately closed. Put multiple commands in bash script instead. (Cannot use to specify multiple commands). This means that paths or filenames with spaces cannot be used. No ‘ or “ in the path/filename to a script. The noted behavior may different than what happens when run from the terminal command line). (Notes below apply when lxterminal -e is used directly in autostart file.
Use the sleep command in a bash script instead.Ĭode: Select all -profile -desktop -profile Notes on using lxterminal -e: Do not attempt to add the sleep command directly in autostart, it won’t work. This can be done with a bash sleep command. In some rare cases you may need to add a delay before starting your script to give the Desktop more time to complete the booting process before your app starts.If your command or app requires network and does not seem to work from autostart, then try enabling the wait for network at boot option in sudo raspi-config.If your script requires keyboard and/or console interaction, then use the lxterminal -e command.Paths to installed apps are not required. Also calls within a script need to have the complete path specified. It is important to use the complete paths to scripts in autostart.All programs launched by autostart run in the background so no need to use & at the end of the command.If you have multiple commands that are dependent on being run in a specific order then you would need to put your commands in a bash script, then call your bash script from autostart. Or the system does not wait for the previous command to complete before starting the next command. The commands in the autostart file are processed independently at near the same time in a parallel fashion. Note that the autostart file is not a bash script and is processed differently.With present, if there is an error on first try, the system will attempt to run the command up to 4 more times before giving up. If not then it can be removed or just ignored. The xscreensaver command is only relevant if you have installed xscreensaver.Then edit autostart and add those 2 lines. To recover, right click anywhere on the screen and select terminal from the menu. If you have made an autostart file without these lines, the desktop will boot to a blank (Openbox) screen. The first 2 lines are important and must not be removed and must also be present if doing the User method.To open System autostart using the nano editor:Ĭode: Select all -profile -desktop -profile -no-splash The System autostart file is located here: /etc/xdg/lxsession/LXDE-pi/ By default, the System autostart is applied to all users and executes each time a user logs in. The System method is easiest as the required autostart file is already present and commands can easily be added with a simple edit. User (Specific Users) *** Default in 'Stretch' and earlier OS releases ***.System (All Users) *** Default in 'Buster' and later OS releases ***.There are 4 autostart methods or options: Other methods such as rc.local or cron do not easily handle GUI programs as they attempt to start the app before the Desktop in ready resulting in failure to open. Requires boot to Desktop (GUI) enabled.Īutostart is particularly useful when you need to run Desktop apps or any scripts which require Desktop (GUI). The autostart feature can be used to automatically start just about any app, script or command at boot (User login).
Raspbian 'Stretch' and before releases used different defaults as noted below. Note the settings and defaults described below are found in the Raspbian 'Buster' and later RPi OS releases.
