dms doctor -v        # Verbose output with paths and details
dms doctor -j        # JSON output for scripting

System Checks​

Operating System​

All GNU/Linux distributions are supported - this information is purely informational.

Architecture​

Only amd64/arm64 is officially supported, although other architectures may work with manual compilation.

Display Server​

DMS only supports Wayland, this check verifies you're not using X11.

Version Checks​

DMS CLI​

DMS CLI is the backend and command-line interface for DMS. Its version should match the version of the quickshell configuration.

Quickshell​

Quickshell is the framework used by DMS. Older versions of quickshell may result in a reduced feature set within DMS.

DMS Shell​

The version of the shell configuration, which should match the DMS CLI version.

Installation Checks​

DMS Configuration​

By default DMS installs its configuration, plugins, and themes in $XDG_CONFIG_HOME/.config/DankMaterialShell/. This check verifies that the configuration directory exists.

shell.qml​

The location of the shell.qml is the installed location of the DMS shell configuration.

Install Type​

Compositor Checks​

All wayland compositors that implement the layer shell protocol are supported, with varying feature sets.

Active Compositor​

Currently running compositor.

Quickshell Features​

These features depend on how Quickshell was built. Using quickshell-git provides full feature support, some builds of quickshell can exclude features based on compilation options.

note

All of these features currently require quickshell-git or quickshell from the Dank Linux repositories (Fedora, Debian, Ubuntu, OpenSUSE)

Polkit​

Polkit is used for escalation prompts, items that require root authorization.

IdleMonitor​

Used to automatically lock, power off monitors, suspend, or hibernate.

IdleInhibitor​

Used to prevent the system from idling or sleeping.

ShortcutInhibitor​

Used to manage keyboard shortcuts, specific to the niri compositor.​

Optional Features​

accountsservice​

Required to persist user profile changes, such as profile picture.

power-profiles-daemon​

Required to manage power profiles. (e.g. performance, balanced, power-saver)

I2C/DDC​

Required for external monitor brightness control, on most distributions requires i2c-tools and the user to be in the i2c group.

Terminal​

Detected terminals (in priority order): ghostty, kitty, alacritty, foot, wezterm

matugen​

DMS leverages matugen with custom color enrichment (dank16) to generate themes for itself and various applications, terminals, and IDEs.

dgop​

Required to use system monitoring widgets and applets (CPU, RAM, Disk, Network, Processes). See dgop documentation for more information.

cava​

Required for audio visualization in media players.

khal​

Required to enrich calendar with events from local, CalDAV, or other sources supported by khal.

Network​

Detected backends: NetworkManager, iwd, systemd-networkd, iwd+systemd-networkd.

DMS supports different network stacks, NetworkManager is recommended for the vast majority of use cases as its also compatible with Gnome, KDE, etc. This is purely for integration within the shell itself (such as conencting to networks, viewing network status, etc.)

danksearch​

Used for indexed filesystem search in the launcher. Use / to initiate a fs search. See DankSearch documentation for more information.

loginctl​

Available on systems using systemd or elogind. Used for various session management features such as lock integration, lock before suspend, etc.

fprintd​

Adds fingerprint authentication support to the lock screen.

Services​

dms.service​

If in use, DMS lifecycle will be managed by systemd. This is optional, DMS can also be started manually or via other init systems.

greetd​

Required for the Dank Greeter. (See DankGreeter documentation for more information.)
