NAME

       Xwayland - an X server for running X clients under Wayland.

SYNOPSIS

       Xwayland [option ...]

DESCRIPTION

       Xwayland  is an X server and a Wayland client. It plays the role of a proxy between legacy
       X clients which do not support the Wayland protocols and the Wayland server.

       Usually, Xwayland is spawned automatically by the Wayland server and runs rootless so that
       X  clients  integrate  seamlessly  with  the  rest  of  the Wayland desktop. It is however
       possible for a user to launch Xwayland non-rootless, mainly for testing purposes.

       Like all of the X servers, Xwayland accepts the command  line  options  described  in  the
       Xserver(7) manual page.  The following additional arguments are supported as well.

       -eglstream
               Use  EGLStream  backend  for  NVidia GPUs. If Xwayland was compiled with EGLStream
               support, this option will instruct  Xwayland  to  try  that  backend  first,  then
               fallback  to  the GBM backend if EGLStream is not supported by the Wayland server.
               Without this option, Xwayland  tries  the  GBM  backend  first,  and  fallback  to
               EGLStream if GBM is not usable.

       -initfd fd
               Add the given fd as a listen socket for initialization of X clients.  This options
               is aimed at Wayland servers which run Xwayland on-demand,  to  be  able  to  spawn
               specific  X  clients  which  need  to  complete before other regular X clients can
               connect to Xwayland, like xrdb.

       -listen fd
               deprecated, use -listenfd instead.

       -listenfd fd
               Add given fd as a listen socket. This option is used by the Wayland server to pass
               Xwayland the socket where X clients connect.

       -noTouchPointerEmulation
               Disable  touch  pointer emulation. This allows the Wayland compositor to implement
               its own pointer emulation mechanism for  X11  clients  that  don't  support  touch
               input.

       -rootless
               Run Xwayland rootless, so that X clients integrate seamlessly with Wayland clients
               in a Wayland desktop. That requires the Wayland server to be an X  window  manager
               as well.

       -shm    Force  the  shared  memory  backend  instead  of glamor (if available) for passing
               buffers to the Wayland server.

       -verbose [n]
               Sets the verbosity level for information printed on stderr.  If the n value  isn't
               supplied, each occurrence of this option increments the verbosity level.  When the
               n value is supplied, the verbosity level  is  set  to  that  value.   The  default
               verbosity level is 0.

       -version
               Show the server version and exit.

       -wm fd  This  option is used by the Wayland server to pass Xwayland the socket where the X
               window manager client connects, when Xwayland is running with -rootless.

ENVIRONMENT

       WAYLAND_DISPLAY
               the name of the display of the Wayland server.

       XWAYLAND_NO_GLAMOR
               disable glamor and DRI3 support in Xwayland, for testing purposes.
