I'm using Debian Stretch LXDE (OpenBox) in a dual monitor setup. I activated the openbox context menu of my second screen by setting

Desktop (right click) -> Desktop Preferences -> Advanced (Tab) -> Show menus provided by window managers when desktop is clicked (Checkbox)

My 1st screen context menu appears as it defaults.

So how do I activate the OpenBox context menu on the 2nd screen?

I already tried to figure out some settings in /etc/xdg/openbox/... but with no clear results.


To clarify my problem: Every screen has its own settings, available by Desktop (right click) -> Desktop Preferences per default. As soon as I activated the window manager context menu the Desktop Preferences disappears and I can't undo my settings.

Right screen desktop context menu Right screen desktop context menu

  • What do you mean with context menu? The root-menu of Openbox (menu.xml)? Or the window-list menu of Openbox? Also it might be helpful to see your rc.xml. Dec 5, 2017 at 10:32
  • I added some screenshots. Every screen provides its own dekstop context menu. And I like to deactivate the openbox context menu on the right one, I activated by checking the option shown on the 3rd screenshot.

So you need to re-enable the PCmanFM Desktop, this is the software which gives you the Windows like menu with create new, etc.

I haven't found the exact option which allows you to do this, but from the PCmanFM wiki, the man page, and the Arch wiki I gathered, that there should be an option in the ~/.config/pcmanfm/default/desktop-items-$XYZ.conf where $XYZ is a number for your screen starting from zero.

There you should find an option to switch the menu from PCmanFM back on. But I don't know which the name of the option and the possible values. But by comparing the two files you will have you should see a relevant difference.

So running

diff ~/.config/pcmanfm/default/desktop-items-*.conf

Should give you a good clue.

In addition there is ~/.config/pcmanfm/default/pcmanfm.conf for genereal options.

  • Feel yourself gifted with beer as much as you can drink! To be specific the solution is to set show_wm_menu=0 in the desktop-items-*.conf file in question.
