Installing KDE on Gentoo hardened

Installing KDE on hardened requires additional USE flags set to get the necessary components enabled, so the desktop is complete.

I have not encountered any issues running KDE under a hardened Gentoo, all common functionality that I have used works as intended.

This begins with assuming you already are on a hardened profile. I am on hardened/linux/amd64 which according to the portage profile structure means my profile is located at /usr/portage/profiles/hardened/linux/amd64. Reference the given link to locate where your profile is located if you are on a different profile.

  • Add the USE flags from:


    to the global USE flags that are in:


This currently contains the following:

USE="consolekit declarative dri kde kipi phonon plasma policykit semantic-desktop xcomposite xinerama xscreensaver"
  • Append the contents of /usr/portage/profiles/targets/desktop/kde/package.use to your /etc/portage/package.use file

This currently contains the following:

  • Emerge KDE

    emerge --ask kde-plasma/plasma-meta

    Alternatively, kde-plasma/plasma-desktop provides the basic desktop, leaving users free to install only the extra packages they require

    emerge --ask kde-plasma/plasma-desktop
  • Upgrade all installed packages, dependencies, and deep dependencies that are outdated or have USE flag changes (avoiding unnecessary rebuilds when USE changes have no impact):

    emerge -auDU --with-bdeps=y @world

You will want to reference the KDE page on the Gentoo wiki to install any application bundles or widgets. Additionally if you want to use SDDM as your display manager as it integrates well with KDE, refer to the following.
