# Building Plasma 5

KDE Plasma 5 is a collection of packages based on top of KDE Frameworks 5 and QML. They implement the KDE Display Environment (Plasma 5).

This package is known to build and work properly using an LFS-10.1 platform.

The instructions below build all of the Plasma 5 packages in one step by using a bash script.

## Downloading KDE Plasma5

The easiest way to get the KDE Plasma5 packages is to use a single wget to fetch them all at once:

    url=http://download.kde.org/stable/plasma/5.21.1/
    wget -r -nH -nd -A '*.xz' -np $url

    The options used here are:
      -r            recurse through child directories
      -nH           disable generation of host-prefixed directories
      -nd           do not create a hierarchy of directories
      -A '*.xz'     just get the *.xz files
      -np           don't get parent directories

## Setting Package Order

The order of building files is important due to internal dependencies. Create the list of files in the proper order as follows:

    cat > plasma-5.21.1.md5 << "EOF"

### Note

The breeze-grub, breeze-plymouth, and plymouth-kcm packages above are all for customized support of Plymouth which is designed to be run within an initial ram disk during boot (see the section called “About initramfs”). The plasma-sdk package is optional and used for software development. The plasma-nano package is used for embedded systems and plasma-phone-components provides phone functionality for Plasma.

## Installation of Plasma5

### Note

When installing multiple packages in a script, the installation needs to be done as the root user. There are three general options that can be used to do this:

1. Run the entire script as the root user (not recommended).

2. Use the sudo command from the Sudo-1.9.5p2 package.

3. Use su -c "command arguments" (quotes required) which will ask for the root password for every iteration of the loop.

One way to handle this situation is to create a short bash function that automatically selects the appropriate method. Once the command is set in the environment, it does not need to be set again.

    as_root()
    {
      if   [ $EUID = 0 ];        then $*
      elif [ -x /usr/bin/sudo ]; then sudo $*
      else                            su -c \\"$*\\"
      fi
    }

    export -f as_root

First, start a subshell that will exit on error:

    bash -e

Install all of the packages by running the following commands:

    while read -r line; do

        # Get the file name, ignoring comments and blank lines
        if $(echo $line | grep -E -q '^ *$|^#' ); then continue; fi
        file=$(echo $line | cut -d" " -f2)

        pkg=$(echo $file|sed 's|^.*/||')          # Remove directory
        packagedir=$(echo $pkg|sed 's|\.tar.*||') # Package directory

        tar -xf $file
        pushd $packagedir

           mkdir build
           cd    build

           cmake -DCMAKE_INSTALL_PREFIX=$KF5_PREFIX \
                 -DCMAKE_BUILD_TYPE=Release         \
                 -DBUILD_TESTING=OFF                \
                 -Wno-dev ..  &&

            make
            as_root make install
        popd

        as_root rm -rf $packagedir
        as_root /sbin/ldconfig

    done < plasma-5.21.1.md5

    exit

If you did not set `$KF5_PREFIX` to `/usr`, create symlinks to allow display managers to find Plasma:

    as_root install -dvm 755 /usr/share/xsessions              &&
    cd /usr/share/xsessions/                                   &&
    [ -e plasma.desktop ]                                      ||
    as_root ln -sfv $KF5_PREFIX/share/xsessions/plasma.desktop &&
    as_root install -dvm 755 /usr/share/wayland-sessions       &&
    cd /usr/share/wayland-sessions/                            &&
    [ -e plasmawayland.desktop ]                               ||
    as_root ln -sfv $KF5_PREFIX/share/wayland-sessions/plasmawayland.desktop

## Configuring Plasma

###

#### Linux PAM Configuration

If you built Plasma with the recommended Linux PAM support, create necessary configuration files by running the following commands as the `root` user:

    cat > /etc/pam.d/kde << "EOF"
    # Begin /etc/pam.d/kde

    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  include        system-session

    # End /etc/pam.d/kde
    EOF

    cat > /etc/pam.d/kde-np << "EOF"
    # Begin /etc/pam.d/kde-np

    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 include        system-password
    session  include        system-session

    # End /etc/pam.d/kde-np
    EOF

    cat > /etc/pam.d/kscreensaver << "EOF"
    # Begin /etc/pam.d/kscreensaver

    auth    include system-auth
    account include system-account

    # End /etc/pam.d/kscreensaver
    EOF

## Starting Plasma5

You can start Plasma5 from a TTY, using xinit-1.4.1.

To start Plasma 5 using xinit-1.4.1, run the following commands:

    cat > ~/.xinitrc << "EOF"
    dbus-launch --exit-with-session $KF5_PREFIX/bin/startplasma-x11
    EOF

    startx

The X session starts on the first unused virtual terminal, normally vt7. You can switch to another vtn simultaneously pressing the keys Ctrl-Alt-Fn (n=1, 2, ...). To switch back to the X session, normally started at vt7, use Ctrl-Alt-F7. The vt where the command startx was executed will display many messages, including X starting messages, applications automatically started with the session, and eventually, some warning and error messages. You may prefer to redirect those messages to a log file, which not only will keep the initial vt uncluttered, but can also be used for debugging purposes. This can be done starting X with:

    startx &> ~/x-session-errors

When shutting down or rebooting, the shutdown messages appear on the vt where X was running. If you wish to see those messages, simultaneously press keys Alt-F7 (assuming that X was running on vt7).
