Abstract:

This video provides a step-by-step guide on installing the Xorg display server and the KDE Plasma desktop environment on a Gentoo Linux system within a virtual machine. It emphasizes the crucial role of the Gentoo Wiki for documentation and problem-solving. The installation process covers configuring make.conf for video card drivers and input devices, managing USE flags for package dependencies, and creating a non-root user with appropriate group permissions for graphical access. The video demonstrates using e-select to set the KDE Plasma profile, followed by emerge commands to install Xorg and the KDE Plasma meta-package. It concludes with configuring the .xinitrc file to launch KDE upon starting X, highlighting the extensive compilation time involved for such a comprehensive desktop environment.

Installing Xorg and KDE Plasma on Gentoo Linux

• 0:00 Introduction: The video addresses a subscriber's request to demonstrate the installation of Xorg and KDE on Gentoo Linux, using a pre-existing Gentoo virtual machine.
• 0:52 Leveraging the Gentoo Wiki: The presenter highlights the Gentoo Wiki as the primary resource for installation instructions and package-specific information, demonstrating how to find the Xorg installation guide.
• 1:42 make.conf Configuration for Xorg: Essential USE flags and VIDEO_CARDS variables are configured in /etc/portage/make.conf. For the virtual machine, INPUT_DEVICES="libinput" and VIDEO_CARDS="virtio qxl" are specified.
• 3:09 elogind for OpenRC: The presenter notes the importance of the elogind package for OpenRC users, though it might not be explicitly required for systemd-based installations.
• 6:52 Emerging Xorg Server: The core Xorg display server is installed using emerge xorg-server. Dependency issues with media-libs/libglvnd requiring the x USE flag are resolved by adding it to package.use.
• 9:36 Installing Xterm: xterm is installed as a fundamental terminal emulator, necessary for basic X functionality even without a full desktop environment.
• 11:13 Verifying Xorg Functionality: startx is successfully run as the root user, confirming the correct configuration of Xorg and video drivers in the virtual machine.
• 11:57 User Account Creation: A new non-root user (chris) is created using useradd, ensuring they are part of the wheel, audio, and crucially, the video groups required to run X.
• 13:31 Setting KDE Plasma Profile: The e-select profile set 10 command (for the systemd/desktop/plasma profile) is used to configure Gentoo for KDE, pulling in many necessary dependencies during a subsequent world update.
• 14:09 Dependency Management: Further USE flag dependencies are encountered and resolved, specifically for media-sound/mpg123 and media-libs/libsoundsfile needing the pulse-audio flag.
• 15:54 Full KDE Plasma Installation: A major system update (emerge --ask --update --newuse @world) is initiated, pulling in over 200 packages for KDE, which requires significant compilation time.
• 19:08 Installing the Plasma Meta-package: After the world update, the kde-plasma/plasma-meta package is explicitly emerged to install the complete KDE Plasma desktop environment, consisting of another substantial set of packages.
• 20:47 Configuring .xinitrc for KDE Launch: The user logs in as the newly created chris user and modifies their ~/.xinitrc file to exec dbus-launch --exit-with-session startplasma-x11, enabling KDE Plasma to start automatically with startx.
• 22:00 Launching KDE Plasma: KDE Plasma successfully loads, and the display resolution is adjusted, completing the installation process.
• 22:38 Key Takeaway: The video reinforces the importance of using the Gentoo Wiki for comprehensive instructions and encourages viewers to seek help if they encounter difficulties.
