I would like to setup an old PC as a thinclient for our VMware View infrastructure. I need to disable the menu that pops up when I right-click on the desktop, along with some other things such as disabling the screen saver.

This is what I have done so far:

  • Disable LXDE screensaver

    Delete @xscreensaver –no-splash from /etc/xdg/lxsession/LXDE/autostart

  • Remove right click desktop menu options

    Right click on desktop and choose Desktop Preferences

    Select the advanced tab and check off Show menus provided by window managers when desktop is clicked

    Edit /etc/xdg/openbox/menu.xml and remove everything between <menu id=”root-menu” label=”Openbox 3”> and </menu>

  • Disable the LXPanel

    Edit /etc/xdg/lxsession/LXDE/autostart and comment out @lxpanel –profile LXDE.

All of this seems to work fine, but when I right-click the desktop I still see this:

Screenshot of the pop-up menu

How do I kill this?

    It seems you have re-enabled pcmanfm desktop menu. Try to re-execute first part of step two.

  • Assuming you mean disable, "check off Show menus provided by window managers when desktop is clicked" is precisely what causes this right-click menu provided by PCManFM to be invoked. Setting that checkbox on hides this menu (leaving everything up to the WM a.k.a. OB) but retains its ability to provide background & icons. Disabling PCManFM altogether in autostart would remove all three facilities.

This question is very old, but you need to remove the line from /etc/xdg/lxsession/LXDE/autostart that is starting pcmanfm. The right-click menu you see there is not from openbox, but from the pcmanfm desktop window.

See this post. You have to modify /etc/xdg/openbox/rc.xml and "smartly" remove all the tags matching a "ShowMenu" command. This will completely disable the OpenBox menus (all of them), but you can adapt it to your needs, as the file contents are pretty intuitive.

You can also modify a copy of this file under ~/.config/openbox/rc.xml to make the changes only for a given (set of) user(s), but being familiar with the thin client world, I think you want to remove it completely.

    This never worked for me. Can you please update the right way tested in Ubuntu 13.10 64-bit but does not work.

    This answer is irrelevant. The pictured menu is provided by PCManFM, which owns the root window used to display the desktop (background & icons). OpenBox has no control whatsoever over that menu. Your answer might mislead readers into spuriously deleting other menus they want to keep. [...inhales...] Setting PCManFM to "Show menus provided by window managers" hides its own right-click menu (& replaces it with OB's if thus configured) but retains its ability to provide background & icons. Disabling PCManFM altogether in autostart would remove all three facilities.
