# Xwayland-22.1.0

## Introduction to Xwayland

The Xwayland package is an Xorg server running on top of the wayland server. It has been separated from the main Xorg server package. It allows running X clients inside a wayland session.

This package is known to build and work properly using an LFS-11.1 platform.

## Installation of Xwayland

Install xwayland by running the following commands:

    sed -i '/install_man/,$d' meson.build &&

    mkdir build &&
    cd    build &&

    meson --prefix=$XORG_PREFIX         \
          -Dxvfb=false                  \
          -Dxkb_output_dir=/var/lib/xkb \
          ..                            &&
    ninja

Building the test framework needs some work. First, weston brings in several dependencies, but the number can be reduced by disabling unneeded features. The meson command for a stripped down build of weston is shown in Upstream continuous integration build.

Furthermore, an X server needs to be running during the build of xts. If not running the tests in a graphical environment, you'll need to enable Xvfb by removing the `-Dxvfb=false` above. The instructions below expect this has been done.

Running the tests involves downloading two other frameworks, in addition to the mentioned optional dependencies:

    mkdir tools &&
    pushd tools &&

    git clone https://gitlab.freedesktop.org/mesa/piglit.git --depth 1 &&
    cat > piglit/piglit.conf << EOF                                    &&
    [xts]
    path=$(pwd)/xts
    EOF

    git clone https://gitlab.freedesktop.org/xorg/test/xts --depth 1   &&

    export DISPLAY=:22           &&
    ../hw/vfb/Xvfb $DISPLAY &
    VFB_PID=$!                   &&
    cd xts                       &&
    CFLAGS=-fcommon ./autogen.sh &&
    make                         &&
    kill $VFB_PID                &&
    unset DISPLAY VFB_PID        &&
    popd

Then the tests can be run with:

    XTEST_DIR=$(pwd)/tools/xts PIGLIT_DIR=$(pwd)/tools/piglit ninja test

Now, as the `root` user:

    ninja install &&
    mkdir -pv /etc/X11/xorg.conf.d

## Command Explanations

sed -i '/install_man/,$d' meson.build: Prevents installing a manual page for Xserver, which is not part of this package.

`-Dxvfb=false`: Prevents building the xvfb program, which is also installed by Xorg-Server-21.1.3. Remove this option if you do not plan to install the X server.

mkdir -pv /etc/X11/xorg.conf.d: This directory is needed to put configuration files for Xwayland. This command ensures that it exists, as some applications might use it without first creating it.
