Installation of Colord

There should be a dedicated user and group to take control of the colord daemon after it is started. Issue the following commands as the root user: 

groupadd -g 71 colord
useradd -c "Color Daemon Owner" -d /var/lib/colord -u 71 \
        -g colord -s /bin/false colord

Prepare Colord by running the following commands: 

./configure --prefix=/usr                \
            --sysconfdir=/etc            \
            --localstatedir=/var         \
            --with-daemon-user=colord    \
            --enable-vala                \
            --disable-argyllcms-sensor   \
            --disable-bash-completion    \
            --disable-static
make

Now Install the package, as the root user: 

make install
[Note]

Note

For unknown reasons, some tests may fail. Note that the system-wide D-Bus daemon must be running or the tests will fail. To test the results, issue: 

make -k check
