Under LXDE desktop manager Alt+F11 can be used to switch a program to full screen.

I use this shortcut so often that'd I rather have certain programs always open in full screen instead of doing it manually.

Is it possible to define some system configuration, or a shell script that'd always launch particular programs in full screen? (Particular not all because I wouldn't want certain small windows like network configuration window and system calendar to open in full screen).


Put this in your ~/.config/openbox/lubuntu-rc.xml in between <applications> tags:

<application class="Firefox" name="Navigator">

To get specific class or name for your applications, use this:

obxprop | grep '^_OB_APP'

and then click with your cursor inside the app window.

  • Running obxprop gives me _OB_APP_CLASS(UTF8_STRING) = "lxpanel" _OB_APP_NAME(UTF8_STRING) = "panel". Not firefox and Navigator as you've specified. Jul 22 '15 at 13:02
  • @KshitizSharma did you click inside firefox window after running obxprop?

  • No. I was clicking on the firefox taskbar entry. Directly clicking inside the window works correctly. Jul 23 '15 at 9:40
  • However, after entering it into lubuntu-rc.xml it only works for firefox. Entries for sublime text and chrome don't result in full screen. Is it working for you? Jul 23 '15 at 9:41
  • Yes, it works. Here is an example snippet of the file: pastebin.com/Grb3Yehs

Generally lxde will have a rc.xml/lxde-rc.xml/lubuntu-rc.xml inside ~/.config/openbox/

Example contents of the xml file:

<application name="firefox">

You should add the following line under your preferred application node (as shown above in the example):


And execute openbox --reconfigure
