(This was tested on Xubuntu 12.04, Xfce 4.10, with xfwm4
as the window manager.)
It is definitely possible to have existing firefox
windows and newly opened ones automatically undecorated if you are using the latest version of devilspie
, version 0.22. This is in the repositories and available to install with:
sudo apt-get install devilspie
There is also a gui called gdevilspie
, but the rules it produced seemed inaccurate and often didn't quite work, so it is easiest to concoct a rule by reading the readme and the manpage.
How the rule was created
All rules created must go in ~/.devilspie
, and have a .ds
extension, so firstly create the folder if it doesn't exist with
mkdir ~/.devilspie
If you want to experiment to find the best window matching condition (class,name,etc), you can create a new file in ~/.devilspie
called test.ds
and place in it (debug)
. Now you can enter devilspie &
and then for every program that you launch, devilspie
will examine and provide some window information in the terminal:
Window Title: 'Mozilla Firefox'; Application Name: 'Firefox'; Class: 'Firefox'; Geometry: 1280x970+0+27
In this case, it is best to select Class (window_class
), as that will reliably identify the window.
The rule
Create a new file called firefox.ds
in ~/.devilspie
and place in it:
; firefox rule to undecorate all existing and new windows
(if (is (window_class) "Firefox") (undecorate))
Comments are introduced with ;
and are not read. You do not need to use begin
in the command unless you are specifying multiple actions, such as (begin undecorate (set_workspace 2)))
instead of just the single action (undecorate))
.
However, for devilspie
to read the new rule you must restart it, so run
killall devilspie
and then restart it with
devilspie &
You have to do this every time when you edit a rule or add a new one in ~/.devilspie
, otherwise the changes or any new rules will not be read.
It is also very important that you add it to startup applications using your desktop environment's menus.

, see man devilspie
or the Ubuntu manpages online.
