Installation of GNOME Session

When running GNOME under Wayland-1.21.0, environment settings are not imported for the user using the system profile. The Wayland developers are currently undecided on a standard method to provide system environment settings for user sessions. To work around this limitation, execute the following command to make gnome-session use a login shell:

sed 's@/bin/sh@/bin/sh -l@' -i gnome-session/gnome-session.in

Install GNOME Session by running the following commands:

mkdir build &&
cd    build &&

meson --prefix=/usr --buildtype=release .. &&
ninja

This package does not come with a test suite.

Now, as the root user:

ninja install

Move the documentation to a versioned directory:

mv -v /usr/share/doc/gnome-session{,-43.0}

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

Command Explanations

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

Starting GNOME

The easiest way to start GNOME is to use a display manager. GDM-43.0 is the recommended display manager.

It is also possible to start GNOME from the command line. However, you must still have GDM-43.0 installed for some portions of the desktop to work. One reason to start from the command line is if you want Wayland support on a system that has the proprietary NVIDIA driver installed, since GDM will not show the Wayland session type on such a system.

To start GNOME using xinit-1.4.2, run the following commands:

cat > ~/.xinitrc << "EOF"
dbus-run-session gnome-session
EOF

startx

Alternatively, to start GNOME with Wayland support, run the following command:

XDG_SESSION_TYPE=wayland dbus-run-session gnome-session
