Introduction to Mutter
Mutter is the window manager for
GNOME. It is not invoked directly,
but from GNOME Session (on a
machine with a hardware accelerated video driver).
This package is known to build and work properly using an LFS 12.4
platform.
Package Information
Mutter Dependencies
Required
docutils-0.21.2, gnome-settings-daemon-48.1,
graphene-1.10.8, libei-1.4.1, libxcvt-0.1.3, libxkbcommon-1.11.0, and pipewire-1.4.7
Recommended
desktop-file-utils-0.28, GLib-2.84.4 (with GObject Introspection),
libdisplay-info-0.3.0, and startup-notification-0.12
Recommended (Required to build the Wayland compositor)
libinput-1.29.0, Wayland-1.24.0, wayland-protocols-1.45, and Xwayland-24.1.8
Optional
dbusmock-0.36.0 (required for tests),
Xorg-Server-21.1.18 (for X11 sessions),
bash-completion,
sysprof, Xvfb (from Xorg-Server-21.1.18 or Xwayland-24.1.8), xvfb-run,
and zenity (the X11 tests
would only run with all of the last three)
Installation of Mutter
Fix an issue with the tests that would otherwise require the
package to be built with debugging information:
sed "/tests_c_args =/s/$/ + ['-U', 'G_DISABLE_ASSERT']/" -i src/tests/meson.build &&
sed "/c_args:/a '-U', 'G_DISABLE_ASSERT'," -i src/tests/cogl/unit/meson.build
Install Mutter by running the
following commands:
mkdir build &&
cd build &&
meson setup --prefix=/usr \
--buildtype=release \
-D tests=disabled \
-D profiler=false \
-D bash_completion=false \
.. &&
ninja
If you want to run the test suite, ensure dbusmock-0.36.0 is installed and issue:
meson configure -D tests=enabled &&
ninja test
The tests require an active X or wayland session. Some tests are
flaky (especially under a high system load) so if a test fails you
can try to re-run it alone with the meson test <test
name> command. A few tests may fail
depending on some system configuration. Don't make any mouse or
keyboard input while the test suite is running or some tests may
fail. You can also test basic functions of Mutter following the section
called “Starting Mutter,” after installing it.
Now, as the root user:
ninja install
Command Explanations
--buildtype=release:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-D bash_completion=false:
Allows building the package without the bash-completion
package installed.
-D tests=disabled: Allow
building the package without dbusmock-0.36.0 installed. It'll be
overridden with meson
configure if running the test suite.
-D profiler=false: Allows
building this package without Sysprof. Remove this option if you've
installed Sysprof and want to
analyze the rendering performance of Mutter.
Starting Mutter
Mutter is normally used as a
component of gnome-shell, but it
can be used as a standalone Wayland compositor too. To run
Mutter as a Wayland compositor, in
a virtual console, issue:
mutter --wayland -- vte-2.91
Replace vte-2.91 with
the command line for the first application you want in the Wayland
session. Note that once this application exits, the Wayland session
will be terminated.
Mutter can also function as a
nested compositor in another Wayland session. In a terminal
emulator, issue:
MUTTER_DEBUG_DUMMY_MODE_SPECS=1920x1080 mutter --wayland --nested -- vte-2.91
Replace 1920x1080 with
the size you want for the nested Wayland session.
