%general-entities; ]> 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). &lfs120_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &mutter-md5sum; Download size: &mutter-size; Estimated disk space required: &mutter-buildsize; Estimated build time: &mutter-time; Mutter Dependencies Required , , , , , and Recommended , , and Recommended (Required to build the Wayland compositor) , , , and Recommended (Runtime) Optional (required for tests), (for X11 sessions), and sysprof Install Mutter by running the following commands: mkdir build && cd build && meson setup --prefix=/usr \ --buildtype=release \ -Dtests=false \ -Dprofiler=false \ .. && ninja The test suite requires an external program called xvfb-run. If you wish to run the tests, you should download and install it before running meson. You can obtain it from xvfb-run, and install it with executable permissions in /usr/bin. xvfb-run needs Xvfb at runtime, and Xvfb can be installed from either or . You should also replace -Dtests=false in the meson command, with -Dtests=true -Dclutter_tests=false. The test suite requires the mutter schema to be installed on the system, so it is better to run the tests after installing the package. You can also test basic functions of Mutter following , after installing it. Now, as the root user: ninja install If you wish to run the tests, remove the reference to Zenity which is not a part of BLFS from one test: sed 's/zenity --[a-z]*/gtk4-demo/' -i ../src/tests/x11-test.sh Now run the test suite: ninja test The tests require an active X or wayland session. One test named input-capture is known to fail. A few other tests may fail depending on the configuration. Don't make any mouse or keyboard input while the test suite is running or some tests may fail. -Dtests=false: Prevents building the tests, and removes a hard requirement on xvfb-run. -Dprofiler=false: Allow building this package without Sysprof. Remove this option if you've installed Sysprof and want to analysis the rendering performance of Mutter. -Dtests=true -Dclutter_tests=false: Building all the tests but the tests for the shipped Clutter library. The Clutter tests are known to fail with --buildtype=release. 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.
