KDE Plasma

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.

pacman -S plasma plasma-wayland-session kde-applications 

Setting up display manager

Start SDDM on boot

Start the Simple Desktop Display Manager (SDDM) on boot to be presented with a graphical login screen.

systemctl enable sddm

Set Keymap for SDDM

NOTE: Executing this command while chrooted into an installation will produce an error that the locale could not be found. Set after rebooting the system, press CTRL + ALT + F3 when SDDM shows up (or any F-key between 2 and 7) to switch tty, log in via the command line and execute the command as root.

localectl set-x11-keymap de

KDE Wallet

KDE Wallet is the integrated password manager and secret store of KDE Plasma. It stores passwords to websites, WiFi networks, network shares, SSH keys and more.

Unlock Wallet automatically on login

Install kwallet-pam (already part of the plasma package group).

There are several caveats to consider:

• Only blowfish encryption is supported
• Wallet cannotcan only be unlocked withif auto-loginthe autologin method saves the password, e.g. when using pam_autologin
• Wallet cannot be unlocked when logging in with a fingerprint
• Wallet must be named kdewallet (default name)
• When choosing to secure Wallet with a password it must match the user password
• Disabling automatic closing of Wallet may be desired to keep it from asking for the password after every use
• When choosing to secure Wallet with a password it must match the user password

YouAutomatic unlocking can also be achieved by setting no password. Do keep in mind, however, that this could also use no password for your Wallet. If doing so you might wantlead to enablepotentially prompts whenever an application tries to access the Wallet to prevent unwantedundesired read/write access to it.your secrets. Enabling Prompt when an application accesses a wallet under Access Control is highly recommended.

When setting up with SDDM as display manager (default for Plasma) no further PAM configuration is necessary, as the config comes with SDDM.

Using Wallet to store SSH key passphrases

Install ksshaskpass (already part of the plasma package group).

Start ssh-agent upon login

Create a new systemd user unit at ~/.config/systemd/user/ssh-agent.service with the following contents:

[Unit]
Description=SSH key agent

[Service]
Type=simple
Environment=SSH_AUTH_SOCK=%t/ssh-agent.socket
# DISPLAY required for ssh-askpass to work
Environment=DISPLAY=:0
ExecStart=/usr/bin/ssh-agent -D -a $SSH_AUTH_SOCK

[Install]
WantedBy=default.target

Autostart .desktop entry

Create ~/.config/autostart/ssh-add.desktop with following contents:

[Desktop Entry]
Exec=ssh-add -q
Name=ssh-add
Type=Application

[Desktop Entry]
Exec=ssh-add -q ~/.ssh/key1 ~/.ssh/key2 ~/.ssh/key3
Name=ssh-add
Type=Application

Setting ksshaskpass as SSHpassphrase agentprompter

NextCreate createthe systemd user environment file at ~/.config/plasma-workspace/env/askpass.shenvironment.d/ssh_askpass.conf with following contents:

#!/bin/sh

export SSH_ASKPASS='/usr/bin/ksshaskpass'

And make the file executable:

chmod +x ~/.config/plasma-workspace/env/askpass.shSSH_ASKPASS_REQUIRE=prefer

This will set ksshaskpass as the default SSH agentkey passphrase storeprompter and makefor graphical password prompts work.environments.

Wallet for Google Chrome password store

To make Google Chrome use Wallet as a password store launch it with --password-store=kwallet5 or --password-store=detect. To make this persistent, add the argument to ~/.config/chrome-flags.conf.
