Usually, the first thing I do after I have started darktable is press F11 to have it in real full-screen mode. I wonder whether I can have this automatically somehow.


Some programs in Lubuntu remember the size when they were closed. Some do not. Lubuntu users can open some or all programs maximized by editing ~/.config/openbox/lubuntu-rc.xml. A very detailed how to can be found at the Community Documentation site

    OP wanted fullscreen rather than maximized. So I've written an answer for that. It is based on the link you provided. – DK Bose Oct 31 '14 at 2:27

I do not use darktable myself but there is a way to launch amenable programs full screen automatically without having to press F11 after loading the program.

To do so, follow all the precautions mentioned in Launching Windows Maximized but use this code in the Applications section of lubuntu-rc.xml:


After determining how you will specify your darktable window with xprop, your "rule" would be something like this (putting what is specific to darktable in place of "geany"):

<application name="geany" type="normal">

As usual, you'll need to run openbox --reconfigure in a terminal after saving lubuntu-rc.xml to let the window manager know you've changed something. Or you may have set up your Openbox right-click menu to have the "reconfigure" option available there.
