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-9.1 platform.

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

User Notes:

Downloading KDE Plasma5

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

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:

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



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-1.8.31 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.

  if   [ $EUID = 0 ];        then $*
  elif [ -x /usr/bin/sudo ]; then sudo $*
  else                            su -c \\"$*\\"

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

       # Fix some build issues when generating some configuration files
       case $name in
           sed -i '/set.HAVE_X11/a set(X11_FOUND 1)' CMakeLists.txt
           sed -i '/X11Extras/a set(X11_FOUND 1)' CMakeLists.txt
           sed -i '/X11.h)/i set(X11_FOUND 1)' CMakeLists.txt

       mkdir build
       cd    build

             -DCMAKE_BUILD_TYPE=Release         \
             -DBUILD_TESTING=OFF                \
             -Wno-dev ..  &&

        as_root make install

    as_root rm -rf $packagedir
    as_root /sbin/ldconfig

done < plasma-5.18.1.md5


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 plasma.desktop ]                                      ||
as_root ln -sfv $KF5_PREFIX/share/wayland-sessions/plasma.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
auth     required

auth     required uid >= 1000 quiet
auth     include        system-auth

account  include        system-account
password include        system-password
session  include        system-session

# End /etc/pam.d/kde

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

auth     requisite
auth     required

auth     required uid >= 1000 quiet
auth     required

account  include        system-account
password include        system-password
session  include        system-session

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

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

auth    include system-auth
account include system-account

# End /etc/pam.d/kscreensaver

Starting Plasma5

You can start Plasma5 from runlevel 3, using xinit-1.4.1, or from runlevel 5, using a Display Manager, such as lightdm-1.30.0.

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


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).

If you intend to start Plasma using a display manager such as lightdm-1.30.0, there will be two entries for Plasma, one for use with Xorg, and another for Wayland. Modify the Xorg entry with the following command, as the root user, so that you can differentiate between the two:

sed '/^Name=/s/Plasma/Plasma on Xorg/' -i /usr/share/xsessions/plasma.desktop


Installed Programs: There are too many plasma programs (50 in /opt/kf5/bin) to list separately here.
Installed Libraries: There are too many plasma libraries (39 in /opt/kf5/lib) to list separately here.
Installed Directories: There are too many plasma directories (over 1000 in /opt/kf5) to list separately here.
