gtk3-nocsd for Debian --------------------- This package disables client side decorations (CSD) in Gtk+3 apps. It does so by using LD_PRELOAD to load the library libgtk3-nocsd.so.0. That overrides certain GLib, GDK and Gtk functions to make sure client side decorations are disabled. The package works automatically: if the package is installed, CSD are disabled on non-GNOME desktops by default. The behavior may be changed both globally and for each individual user. 1. Changing the behavior globally: If CSD should remain enabled by default, an administrator may edit the file /etc/X11/Xsession.d/01gtk3-nocsd and change the variable GTK_CSD from 0 to 1. 2. Changing the behavior for an individual user: export GTK_CSD=1 into their ~/.xsessionrc to override this behavior (or export GTK_CSD=0 to override the administrator's behavior if they changed the default). 3. Alternative options: If one wants to set GTK_CSD=0 without causing this to preload the library, one may also set the variable GTK3_NOCSD_IGNORE=1 (in either one of the aforementioned files). 4. Running individual programs without CSD: This package also installs the gtk3-nocsd wrapper that executes programs with the library preloaded and GTK_CSD=0. For example, gtk3-nocsd gedit would start gedit without client side decorations (regardless of any global or per-user settings). Note that any program started from a program that was wrapped in such a way will also have CSD disabled. 5. Programs from different architectures (e.g. 32bit) If you are running programs from foreign architectures on your system, e.g. i386 (32bit) programs on a amd64 machine, you might get warnings about libgtk3-nocsd.so.0 not being found: ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored. In that case, you can install the libgtk3-nocsd0 package for the foreign architecture, e.g.: apt-get install libgtk3-nocsd0:i386
