Issue the following commands as the root user: groupadd -g 64 sddm && useradd -c "SDDM Daemon" \ -d /var/lib/sddm \ -u 64 -g sddm \ -s /bin/false sddm First, fix the application to start upowerd, if necessary, and after login, start the session with ck-launch-session: sed -e '/UPOWER_SERVICE)/ s:^://:' \ -i src/daemon/PowerManager.cpp && sed -e 's/eval exec/& ck-launch-session /' \ -i data/scripts/Xsession Install SDDM by running the following commands: mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX=/usr \ -DCMAKE_BUILD_TYPE=Release \ -DENABLE_JOURNALD=OFF \ -DDBUS_CONFIG_FILENAME=sddm_org.freedesktop.DisplayManager.conf \ -Wno-dev .. && make This package does not come with a test suite. Now, as the root user: make install && install -v -dm755 -o sddm -g sddm /var/lib/sddm -DCMAKE_BUILD_TYPE=Release: This switch is used to apply additional compiler optimizations. -DENABLE_JOURNALD=OFF: This switch is used because BLFS does not support systemd. -DDBUS_CONFIG_FILENAME=sddm_org.freedesktop.DisplayManager.conf: This switch is used for safety reason: other DMs already use org.freedesktop.DisplayManager.conf. Verify in your system taht this is not the case, if you wish to remove it. -DBUILD_MAN_PAGES=ON: This switch may be used if you want the man pages to be installed. Notice that you need Docutils to build them. /etc/sddm.conf /etc/sddm.conf This file is not installed with the build instructions, and default values are used by sddm. In order to generate the example sddm.example.conf, issue: sddm --example-config > sddm.example.conf We repeat, this command generates an example config file. If there is an already previously installed /etc/sddm.conf, it will generate a replica. If there is no yet the /etc/sddm.conf file, as the root user, copy the example file to /etc/sddm.conf: cp -v sddm.example.conf /etc/sddm.conf Normally, you want to edit this file. For example, if Xorg is installed in /opt, use your preferred editor as the root user to replace the XauthPath default path by /usr/bin/xauth. Or, as the root user, issue sed -e '/ServerPath/ s|usr|opt/xorg|' \ -i.orig /etc/sddm.conf This command will do the substitution and create a copy of the original file with name /etc/sddm.conf.orig. From now on, we will describe how to modify configurations using sed, but of course you may rather use your preferred editor as the root, instead. You generally want the server option that comes in sddm.example.conf, for security reasons. Unless you want a remote machine to use the local X server, in which case, as the root user, issue: sed -e 's/-nolisten tcp//'\ -i /etc/sddm.conf Desktop (Notebook) users, normally wish the Num Lock key on (off). For that, as the root user, issue: sed -e 's/\"none\"/\"on\"/' \ -i /etc/sddm.conf That was for Desktop users. For Notebook users, replace \"on\" by \"off\", in the command above. Install the /etc/rc.d/init.d/sddm init script from the package. sddm make install-sddm If you have built SDDM with Linux PAM support, create the necessary configuration files by running the following commands as the root user: cat > /etc/pam.d/sddm << "EOF" # Begin /etc/pam.d/sddm auth requisite pam_nologin.so auth required pam_env.so auth required pam_succeed_if.so uid >= 1000 quiet auth include system-auth account include system-account password include system-password session required pam_limits.so session include system-session # End /etc/pam.d/sddm EOF cat > /etc/pam.d/sddm-autologin << "EOF" # Begin /etc/pam.d/sddm-autologin auth requisite pam_nologin.so auth required pam_env.so auth required pam_succeed_if.so uid >= 1000 quiet auth required pam_permit.so account include system-account password required pam_deny.so session required pam_limits.so session include system-session # End /etc/pam.d/sddm-autologin EOF cat > /etc/pam.d/sddm-greeter << "EOF" # Begin /etc/pam.d/sddm-greeter auth required pam_env.so auth required pam_permit.so account required pam_permit.so password required pam_deny.so session required pam_unix.so -session optional pam_systemd.so # End /etc/pam.d/sddm-greeter EOF If the sddm bootscript has been installed, start it by running, as root user: /etc/rc.d/init.d/sddm start By convention, X should be executed at runlevel 5, consequently, the same is true for sddm. However, LFS default runlevel is 3. Changing to runlevel 5, from a console terminal, as root user, starts the sddm bootscript, bringing up the greeter screen: init 5 In order to permanently set the default to 5, starting the sddm greeter screen automatically, modify /etc/inittab. As the root user: cp -v /etc/inittab{,-orig} && sed -i '/initdefault/ s/3/5/' /etc/inittab The greeter offers a list of available sessions, depending on the Window Managers and Desktop Environments installed. The list includes sessions which have a corresponding .desktop file installed under /usr/share/xsessions. Most of the Window Managers and Desktop Environments automatically provide those files, but if necessary, you may include a custom one. Four themes are installed at /usr/share/sddm/themes: circles, elarun, maldives, and maui. The default theme is maui. You can install other themes in that directory. In order to change the theme, you need to edit /etc/sddm.conf, using your preferred text editor, to change the default maui theme, replacing Current=maui by Current=<insert new theme name here>, e.g. Current=maldives. In order to see the theme without leaving the session, issue: sddm-greeter --test-mode --theme <theme path> This application works well, but there are issues. You find the mainstream known issues at Issues. The BLFS development team have found some issues. In the next couple of paragraphs, due to a problem with sddm-greeter, we mention how to define the keyboard used there. Notice that this is also the keyboard that will be used in the X session, unless there is a configuration in the Desktop Environment or in the Window Manager overriding it, afterwards. Keyboard selection: the greeter shows a double question mark or the wrong keyboard. When you start to type the password or user name (depending on the theme, only password), the right keyboard selection magically appears. Optionally, a workaround is to include the keyboard list in /usr/share/sddm/scripts/Xsetup script, as the root user: echo 'setxkbmap "<your keyboard comma separated list>"' >> \ /usr/share/sddm/scripts/Xsetup E.g. echo 'setxkbmap "fr,gb,br,us"' >> /usr/share/sddm/scripts/Xsetup. You can be accurate defining the keyboard(s), for example: echo 'setxkbmap -model pc105 -layout br,us -variant abnt2,dvorak -keycodes evdev' >> /usr/share/sddm/scripts/Xsetup. See man setxkbmap. Dircolors: the /etc/dircolors file is not honoured. Particularly, the compressed files are not displayed in red colour. If this happens, a workaround is to issue, as the root user: echo "source /etc/profile.d/dircolors.sh" >> /etc/bashrc It has been reported that this package does not work with Xorg installed with a prefix other than /usr.
