Rebuild of #3388 on current master: the previous branch was cut from an older base and reverted unrelated fixes in the gamma stack and the display settings UI. ICC profiles: - core/internal/icc: ICC v2/v4 parser (TRC, LUT8/16 and parametric curves, vcgt, description/version/color space) plus gamma ramp generation, with synthetic coverage and optional vendor-profile tests (ICC_TEST_DIR). - wayland manager: load iccProfiles from the compositor's DMS config dir, build the ramp from the profile when one is set (falling back to the temperature ramp when it is missing or unparsable), and re-apply on output hotplug and after resume. - ICC ramps apply while the night light schedule is disabled; outputs without a profile keep an identity ramp. - desc/mluc offsets are validated before slicing, so a malformed profile returns an error instead of panicking the daemon. Per-output temperature: - outputTemps in the same config; SetOutputTemp accepts 1000-10000K and the Display Config slider exposes 3000-10000K, which matters for displays calibrated at a higher white point (e.g. a 7000K profile). Gamma control lifecycle: - needsControls() now keeps the controls alive for configured ICC profiles and per-output temperatures, so toggling the night light off no longer destroys the controls and drops the ramps. - Re-apply paths clear the per-output dedup state instead of adding a manager-level guard, which would have suppressed contrast-only writes and the post-resume forced resend (#1235), and left a recreated control without a ramp. - Monitor sleep/disconnect still re-establishes controls when an output comes back. IPC / CLI / UI: - wayland.icc.{getStatus,apply,remove,listOutputs,setTemp,getTemps} - dms icc list | info <file> | apply <output> <file> | remove <output> | status - Display Config output card gains a Color Profile row (browse/apply/remove with description, version, color space and active state) and a per-output color temperature slider, backed by Services/ICCService.qml. Config path: - DMSConfigDir() follows the compositor layout (niri/dms, hypr/dms, mango/dms) via the shared compositor detection and utils.XDGConfigHome(), replacing the hardcoded niri path in both the manager and `dms icc`. Tests: TZ=UTC go test ./... (60 packages ok), including red/green coverage for the icc parser bounds checks and needsControls().
DMS Quickshell Interface
QML-based desktop shell interface for DankMaterialShell providing panels, widgets, and overlays.
See root README for project overview and installation.
Architecture
Modular QML Structure
Modules/- UI components (panels, widgets, overlays)Services/- System integration singletons (audio, network, bluetooth)Widgets/- Reusable UI controlsCommon/- Shared resources and themes
Technology Stack
- Quickshell - QML-based shell framework
- Qt/QtQuick - UI rendering and controls
- Material Design 3 - Design system and theming
Development
Run the shell:
quickshell -p quickshell/
Code formatting:
qmlfmt -t 4 -i 4 -b 250 -w path/to/file.qml
make lint-qml # Run from repo root; requires quickshell/.qmlls.ini (generated by `qs -p quickshell/`)
# Uses Qt 6 qmllint. Override path with QMLLINT=/path/to/qmllint if needed.
# Auto-detects `qmllint6`, Fedora's `qmllint-qt6`, `/usr/lib/qt6/bin/qmllint`, then `qmllint`.

Network
NetworkService- NetworkManager WiFi controlBluetoothService- BlueZ Bluetooth management
Display
DisplayService- Brightness control and night modeWallpaperService- Wallpaper management and effects

NiriService- Niri workspace integrationHyprlandService- Hyprland workspace integrationPluginService- Plugin discovery and lifecycle
Widgets
Reusable Material Design 3 components in Widgets/:
DankIcon- Icon component with Material fontDankSlider- Enhanced slider with animationsDankToggle- Toggle switch componentDankTabBar- Tab bar implementationDankGridView- Grid layout with adaptive columnsDankListView- Scrollable list viewDankTextField- Text input with validationDankDropdown- Dropdown selectionDankPopout- Base for overlay componentsStateLayer- Material interaction states
Theming
Dynamic Color Schemes
Wallpaper-based theming using matugen:
import qs.Common
Rectangle {
color: Theme.container
border.color: Theme.outline
}
Theme singleton provides Material Design 3 color system, spacing, fonts, and elevation.
Application Themes
Templates in scripts/templates/ generate themes for:
- GTK 3/4
- Qt5/Qt6
- Alacritty, Kitty, Ghostty, Foot, Wezterm terminals
- Neovim
- VSCode/VSCodium
- Firefox
Multi-Monitor Support
Per-monitor panel instances using Quickshell Variants:
Variants {
model: Quickshell.screens
PanelWindow {
screen: modelData
// Per-screen configuration
}
}
Workspace switchers adapt to compositor (Niri/Hyprland).
Plugin System
External plugins in ~/.config/DankMaterialShell/plugins/:
Widget plugins - UI components in DankBar Daemon plugins - Background processes without UI
Plugin manifest (plugin.json):
{
"id": "pluginId",
"name": "Plugin Name",
"version": "1.0.0",
"type": "widget",
"component": "./Widget.qml",
"settings": "./Settings.qml",
"permissions": ["settings_read", "settings_write"]
}
Plugins access pluginService for persistent data:
pluginService.savePluginData("pluginId", "key", value)
pluginService.loadPluginData("pluginId", "key", defaultValue)
IPC Integration
Backend IPC socket communication:
import Quickshell.Io
Process {
command: ["dms", "ipc", "call", "spotlight", "toggle"]
running: true
}
Common IPC commands exposed through services for reactive property bindings.
Code Conventions
Component Structure:
import QtQuick
import Quickshell
import qs.Common
import qs.Services
Item {
id: root
property type name: value
signal customSignal(type param)
Component { /* children */ }
}
Services (Singletons):
import QtQuick
import Quickshell
pragma Singleton
pragma ComponentBehavior: Bound
Singleton {
id: root
property bool featureAvailable: false
property type currentValue: defaultValue
function performAction(param) { /* implementation */ }
}
Guidelines:
- Use
Theme.propertyNamefor consistent styling - Bind directly to service properties for reactivity
- Use
DankIconfor all icons - Implement feature detection and graceful degradation
- 4-space indentation, no unnecessary comments
