How to add startup applications in lubuntu?

Solution 1:

There is a default application for this on the Lubuntu. Check it out:

1. Press the Lubuntu icon on the bottom left;
2. Select "Preferences" > "Default applications for LXSession";
3. In the opened window, select the option "Autostart";
4. Now you can enable or disable the autostarted applications, check/uncheck one in the listm or set manually on the field and pressing the "Add" button.

Solution 2:

You can install the programm lxsession-edit from the software center. It will give you an interface like the "startup applications" app.

Or you can add programs by editing the file /etc/xdg/lxsession/LXDE/autostart. (In new Lubuntu is path /etc/xdg/lxsession/Lubuntu/autostart)
To do this press Alt+F2 and type gksu gedit.

Or the cleanest way (that didn't work for you) adding .desktop files to /home/username/.config/autostart and make sure they're marked as executables.

Here is a default syntax for a .desktop file with some of the most important entries.

[Desktop Entry]
Type=Application
Encoding=UTF-8
Name="NAME OF THE APPLICATION"
Comment="WHAT DOES THE APP DO?"
Exec="EXECUTABLE PATH OF APPLICATION"
Hidden=false
NoDisplay=false
Terminal=false

Example:

[Desktop Entry]
Type=Application
Encoding=UTF-8
Name=Firefox
Comment=Firefox Web Browser
Exec=firefox
Hidden=false
NoDisplay=false
Terminal=false

For applications that have their binaries in /usr/bin, you don't have to put the full path, just the name of the executable.

Save as YOUR_APPNAME.desktop in ~/.config/autostart/.

Log out and back in and it should have worked.

Solution 3:

In Lubuntu 18.10 onwards (i.e. with LXQt):

1. Lubuntu icon on bottom left (start button);
2. Preferences;
3. LXQt settings;
4. Session Settings (or LXQt Configuration Centre, followed by Session Settings);
5. In the window that opens, select "Autostart" on the left, then click "Add" on the right.

You can also remove items from the Autostart list by unchecking their boxes - as long as you know what you're removing.

Solution 4:

This works for Lubuntu based on Ubuntu 18.10:
Preferences -> LXQt settings -> Session Settings -> Autostart
