NAME

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

SYNOPSIS

       gtk3-nocsd command [ command arguments ... ]

       symlinked-command
              [ command arguments ... ]

DESCRIPTION

       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.

OPTIONS

       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.

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

INTEGRATION IN DEBIAN

       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.

USAGE VIA SYMLINKS

       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.

CAVEATS

       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.
