gnome-session-49.2

Introduction to GNOME Session

The GNOME Session package contains the GNOME session manager.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

GNOME Session Dependencies

Required

elogind-255.22, gnome-desktop-44.5, JSON-GLib-1.10.8, Mesa-25.3.5, and UPower-1.91.1

Optional

xmlto-0.0.29, and libxslt-1.1.45 with docbook-xml-4.5 and docbook-xsl-nons-1.79.2 (to build the documentation)

Installation of GNOME Session

Install GNOME Session by running the following commands:

mkdir build &&
cd    build &&

meson setup --prefix=/usr              \
            --buildtype=release        \
            -D man=false               \
            -D docbook=false           \
            -D systemduserunitdir=/tmp \
            ..                         &&
ninja

This package does not come with a test suite.

Now, as the root user:

ninja install

If you generated the documentation, move it to a versioned directory:

mv -v /usr/share/doc/gnome-session{,-49.2}

This package creates two Xorg based .desktop files in the /usr/share/xsessions/ directory, and two Wayland based .desktop files in the /usr/share/wayland-sessions/ directory. Only one is needed in each directory on a BLFS system, so prevent the extra files showing up as options in a display manager. As the root user:

rm -fv /usr/share/xsessions/gnome.desktop &&
rm -v /usr/share/wayland-sessions/gnome.desktop

Now, as the root user, remove systemd units that are useless on SysV systems:

rm -rv /tmp/{*.d,*.target,*.service}

The startup sequence of gnome-wayland needs to create a dbus session. On SysV, this has to be added to the shipped gnome-wayland.desktop file, which is written for systemd. As the root user:

sed -e 's@^Exec=@&/usr/bin/dbus-run-session @' \
    -i /usr/share/wayland-sessions/gnome-wayland.desktop

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-D man=false -D docbook=false: These parameters disable building documentation. Omit them if you have built the optional dependencies.

-D x11=true: This option enables support for X11 sessions. X11 support is deprecated and will be removed in GNOME 50.
