GDM のインストール

It is recommended to have a dedicated user and group to take control of the gdm daemon after it is started. Issue the following commands as the root user:

groupadd -g 21 gdm &&
useradd -c "GDM Daemon Owner" -d /var/lib/gdm -u 21 \
        -g gdm -s /bin/false gdm &&
passwd -ql gdm

一般ユーザーになって、以下のコマンドを実行し GDM をビルドします。

./configure --prefix=/usr         \
            --sysconfdir=/etc     \
            --localstatedir=/var  \
            --without-plymouth    \
            --disable-static      \
            --enable-gdm-xsession \
            --with-pam-mod-dir=/lib/security &&


root ユーザーとなって以下を実行します。

make install &&
install -v -m644 data/gdm.service /lib/systemd/system/gdm.service


--disable-static: このスイッチはスタティックライブラリをインストールしないようにします。

--with-initial-vt=7: Use this switch to make GDM start on VT7 instead of the first free VT.

--without-plymouth: GDM now explicitly requires plymouth to be installed. Use this switch to disable this dependency.

--with-default-pam-config=lfs: Use this switch if you did not create the /etc/lfs-release file or distribution auto detection will fail and you will be unable to use GDM.

--enable-gdm-xsession: This enables the installation of the GDM Xsession file.

GDM の設定




The GDM daemon is configured using the /etc/gdm/custom.conf file. Default values are stored in GSettings in the gdm.schemas file. It is recommended that end-users modify the /etc/gdm/custom.conf file because the schemas file may be overwritten when the user updates their system to have a newer version of GDM.

Systemd Unit

To start the gdm daemon at boot, enable the previously installed systemd unit by running the following command as the root user:

systemctl enable gdm


インストールプログラム: gdm, gdmflexiserver, gdm-screenshot
インストールライブラリ:, (PAM モジュール)
インストールディレクトリ: /etc/gdm, /usr/include/gdm, /usr/share/gdm, /usr/share/help/*/gdm, /var/cache/gdm, /var/lib/gdm, /var/log/gdm, /var/run/gdm
