KDE Plasma

Base Plasma Packages

Base KDE Plasma packages for the full Plasma experience. Bundle with other packages to prevent package conflicts providing the same functionality.

TIP: Include any and all packages you want installed in a list to pacman. That way pacman will resolve package dependencies correctly and not install packages that would cause conflicts with other packages later on in the setup; e.g. the plasma group installs pulseaudio as a dependency of plasma-pa, but pulseaudio and pipewire (see below) are conflicting packages, meaning they can't both be installed at the same time prompting you to remove one or the other. Explicitly selected packages take precedence over packages auto-selected via dependencies.

Video Acceleration

Drivers for hardware accelerated desktop rendering, improving performance and fidelity.

Intel

pacman -S mesa vulkan-intel intel-media-driver libva-intel-driver
yay -S intel-hybrid-codec-driver

AMDGPU

pacman -S xf86-video-amdgpu libva-mesa-driver vulkan-radeon amdvlk 

Audio

Nvidia

Nouveau open source driver

pacman -S libva-mesa-driver mesa-vdpau
yay -S nouveau-fw

Proprietary driver

pacman -S nvidia nvidia-utils # Includes Vulkan driver

Audio

Use PipeWire as a more current and modern low-latency sound server. Also better suited for WebRTC screen sharing and recording in Wayland sessions (GNOME uses Wayland by default)

pacman -S pipewire pipewire-pulse pipewire-jack pipewire-alsa wireplumber

Bluetooth

pacman -S bluez bluez-utils
systemctl enable bluetooth

Spell Checking

pacman -S hunspell hunspell-de hunspell-en_US hyphen hyphen-de 

Printing

pacman -S cups logrotate system-config-printer
systemctl enable cups
systemctl enable logrotate.timer

Firefox

pacman -S firefox firefox-i18n-de
echo "MOZ_X11_EGL=1" >> /etc/environment
echo "MOZ_ENABLE_WAYLAND=1" >> /etc/environment
echo "MOZ_WEBRENDER=1" >> /etc/environment

Alternatively, navigate to about:config and set gfx.webrender.all to true to enable WebRender compositor.
