Question:
I am running Ubuntu 16.04. I want to undecorate (remove borders and title bar) of a window. I found an old posted scripts on the net claimed to be working but it doesn't work now.
To undecorate:
xprop -f _MOTIF_WM_HINTS 32c -set _MOTIF_WM_HINTS "0x2, 0x0, 0x0, 0x0, 0x0" To redecorate:
xprop -f _MOTIF_WM_HINTS 32c -set _MOTIF_WM_HINTS "0x2, 0x0, 0x1, 0x0, 0x0" Though this python script works
#! /usr/bin/python2 import gtk.gdk w = gtk.gdk.window_foreign_new( gtk.gdk.get_default_root_window().property_get("_NET_ACTIVE_WINDOW")[2][0] ) w.set_decorations( (w.get_decorations()+1)%2 ) # toggle between 0 and 1 gtk.gdk.window_process_all_updates() gtk.gdk.flush() How can I toggle window decoration from terminal without python?
Solution:1
This will not work in compiz! Compiz expects that _MOTIF_WM_HINTS property type is _MOTIF_WM_HINTS, but xprop command sets it to CARDINAL. If you use xprop | grep _MOTIF_WM_HINTS you will see this:
_MOTIF_WM_HINTS(CARDINAL) = 2, 0, 0, 0, 0
It should be like this:
_MOTIF_WM_HINTS(_MOTIF_WM_HINTS) = 2, 0, 0, 0, 0
Your python script works, because GTK+ properly sets this property. :)
