Openbox will give the functionality you are looking for to windows whose _OB_APP_TYPE
property is set to "desktop" (You can use obxprop
to check the properties of a window).
So we need to set the _OB_APP_TYPE
for your terminator window to "desktop" so that this will happen.
Reading through the openbox source code, in client.c
I could see that _OB_APP_TYPE
is inherited from _NET_WM_WINDOW_TYPE
. So I looked for an application that could change _NET_WM_WINDOW_TYPE
. The application I found is called devilspie
.
First, install it:
sudo apt-get install devilspie
Next, we'll create the folder for devilspie
configuration files:
mkdir ~/.devilspie
Now we will add a config file that tells devilspie
to look for applications named terminator
and set the window type of them to desktop
. Put the following into ~/.devilspie/terminator.ds
:
(if
(is (application_name) "terminator")
(begin
(wintype "desktop")
)
)
Now, if you run devilspie
(or devilspie -a
to affect existing windows instead of just newly created ones) you'll notice if you use obxprop
on terminator that _NET_WM_WINDOW_TYPE
has changed, but _OB_APP_TYPE
has not yet. Let's use xdotool
to unmap and remap the window (in X11 terminology this means we will stop drawing and begin drawing the window), which should force openbox to notice the value.
Install xdotool:
sudo apt-get install xdotool
Then we run the following script to find the terminator
window, unmap it, wait until it has been unmapped, then remap it. We also resize the window because when it was unmapped and remapped it lost its maximization:
xdotool search --class "terminator" windowunmap --sync windowmap windowsize %1 1024 768
Replace 1024 768
with your resolution. Also note that newer versions of xdotool
than those found in Debian's apt repo support using 100% 100%
instead of a static resolution. You can find .deb
packages for newer versions of xdotool
at xdotool's googlecode page.
The terminator window will immediately become undecorated, and if you now use obxprop
, you will see that both values have been set properly. If you now press the key you bound ToggleShowDesktop
to a few times, the terminator window will always stay active.
To make this persistent, you'll want to run these commands on login. The LXDE Wiki Page for LXSession shows several different ways to do this (global, per-user, per-profile, etc). Assuming you want these settings just for your user and under the LXDE profile (the default), you'll want to edit ~/.config/lxsession/LXDE/autostart
and add the commands we ran, keeping in mind that the xdotool command needs to be run after terminator's window has been rendered, so do something like (sleep 1s & xdotool ...)
. You could also set these commands up as keybinds in openbox if you wish.
xrandr
1 may be the solution you are looking for so that you don't need to log out/log in.
From How to use xrandr:
The old days where you had to restart X when plugging a new monitor
are gone. With RandR 1.2, you can plug/unplug monitors whenever you
want. Running the following line will query all outputs and enable
them with their default mode:
$ xrandr --auto
Ideally, the default config works for you. Otherwise, configure xrandr as needed. This is probably a good enough solution for most people to start using the display without logging out.
For details on automatically detecting when the monitor is plugged in, I have added an answer2 to the existing thread A tool for automatically applying RandR configuration when external display is plugged in
