gtk3-nocsd - transparently disable Gtk+3 client side decorations (CSD)

       When  using  gtk3-nocsd  with  setarch  (including  alias  such  as linux32), or anyway with chroots with
       different architectures than the host's, make sure  to  install  the  matching  architecture  version  of
       libgtk3-nocsd.so.0  both  in the setarch environment and the host's environment. Note that the gtk3-nocsd
       binary must then be installed in a system path (/usr/bin, /usr/local/bin,  ...),  so  that  it  will  set
       LD_PRELOAD  to  just  the  library  name  and let the dynamic linker find it automatically - allowing the
       dynamic linker to pick the version for the correct architecture. If gtk3-nocsd  is  not  installed  in  a
       system path, it will use a full path, allowing only for a single version of the library to be used.

                                                  October 2015                                     gtk3-nocsd(1)

gtk3-nocsd  runs  a command in the environment where Gtk+3 client side decorations (CSD) are disabled, by
       using LD_PRELOAD to load the library libgtk3-nocsd.so.0 that overrides some GLib, GDK and Gtk  API  calls
       with customized variants.

       Usage of gtk3-nocsd is not required in Debian by default, because gtk3-nocsd functionality  is  activated
       automatically  on Xsession startup if anything but GNOME is used. On GNOME CSDs will remain enabled. Both
       the administrator and each individual user may override those defaults.

       Administrators   may   choose    to    re-enable    CSDs    by    default    by    editing    the    file
       /etc/X11/Xsession.d/01gtk3-nocsd and changing the following setting:

              export GTK_CSD=1

       Users  may  choose to override this (in either way) by adding a similar line to their ~/.xsessionrc.  For
       more details, please see /usr/share/doc/gtk3-nocsd/README.Debian.

command
              The  command  to execute. It may be either a full path or the name of the command in PATH. In case
              command cannot be found in PATH, gtk3-nocsd will fail.

       commandarguments
              Arbitrary number of arguments to pass to the command being executed.

gtk3-nocsdcommand [ commandarguments ... ]

       symlinked-command
              [ commandarguments ... ]

       If a symlink to gtk3-nocsd under a different name is called, gtk3-nocsd will assume that the name it  was
       called  under is the name of the command that is supposed to be executed. It will look for the command in
       the PATH environment variable, excluding itself, and execute it with  the  proper  environment  variables
       set. This is useful when is not desirable to add gtk3-nocsd to the system-wide LD_PRELOAD or if it should
       be applied only to certain applications.
