Pick the block for your distro. Repo, AUR, and Nix installs are the best default for CLI users because they use the normal system update flow. GitHub .deb/.rpm downloads are one-off installs; use them only when you do not want to add a repo.

Debian and Ubuntu

Also use this path for Linux Mint, Pop!_OS, and other Debian-based distros.

sudo apt update
sudo apt install curl gpg
sudo install -d -m 0755 /usr/share/keyrings
curl -fsSL https://wayscriber.com/apt/WAYSCRIBER-GPG-KEY.asc | gpg --dearmor | sudo tee /usr/share/keyrings/wayscriber.gpg > /dev/null
echo "deb [signed-by=/usr/share/keyrings/wayscriber.gpg] https://wayscriber.com/apt stable main" | sudo tee /etc/apt/sources.list.d/wayscriber.list
sudo apt update
sudo apt install wayscriber
# Optional GUI configurator:
sudo apt install wayscriber-configurator

Fedora and RHEL

Also use this path for Rocky Linux, AlmaLinux, Nobara, and other RPM-based distros.

cat <<'EOF' | sudo tee /etc/yum.repos.d/wayscriber.repo
[wayscriber]
name=Wayscriber Repo
baseurl=https://wayscriber.com/rpm
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://wayscriber.com/rpm/RPM-GPG-KEY-wayscriber.asc
EOF
sudo dnf clean all
sudo dnf install wayscriber
# Optional GUI configurator:
sudo dnf install wayscriber-configurator

Arch Linux

Also use this path for Manjaro, CachyOS, and other Arch-based distros.

yay -S wayscriber-bin    # prebuilt binary
# or:
yay -S wayscriber        # build from source
# Optional GUI configurator:
yay -S wayscriber-configurator

Use your preferred AUR helper if you do not use yay.

Nix and NixOS

nix run github:devmobasa/wayscriber -- --active
# or install to your profile:
nix profile install github:devmobasa/wayscriber
wayscriber --active
# Optional GUI configurator:
nix profile install github:devmobasa/wayscriber#wayscriber-configurator

Unpinned GitHub flake URLs follow the default branch. To run or install a specific release, pin the tag, for example:

nix run 'github:devmobasa/wayscriber?ref=v0.9.19' -- --active
nix profile install 'github:devmobasa/wayscriber?ref=v0.9.19'
nix profile install 'github:devmobasa/wayscriber?ref=v0.9.19#wayscriber-configurator'

For browser downloads, see No terminal install. For source builds, see From Source.

First launch

After a package-manager install:

wayscriber --version
wayscriber --active

If you used the nix run command above, it already launches the app without installing it to PATH.

Press F1 or F10 for help, Shift+F1 for quick reference, Ctrl+K for the command palette, and Escape to hide or exit.

Daily daemon setup

Daemon mode is preferred for daily use because toggles are faster and session state survives between activations.

systemctl --user enable --now wayscriber.service
wayscriber --daemon-toggle

Bind wayscriber --daemon-toggle to a global shortcut in your compositor or desktop environment. Ubuntu GNOME users: Super+G is a good default because Super+D is often reserved.

For distro-specific package details, see Installation. For keybinding examples and daemon behavior, see Usage.

Installation

Pick an install path

You want	Use
Fast CLI install with auto-updates on Debian/Ubuntu/Mint/Pop!_OS	Debian / Ubuntu repo
Fast CLI install with auto-updates on Fedora/RHEL/Rocky/Alma/Nobara	Fedora / RHEL repo
Arch, Manjaro, CachyOS, or another Arch-based distro	AUR, preferably `wayscriber-bin` for the prebuilt package
Nix profile, `nix run`, or NixOS flake setup	NixOS / Nix
Browser-based install without adding a repo	GitHub Releases
Hacking on wayscriber or building a local binary	From Source

Install the main wayscriber package first. wayscriber-configurator is optional and does not include the wayscriber binary.

No terminal install (GitHub Releases)

If you prefer downloading files in a browser instead of using package-manager commands:

Open latest release.
Install the main app package that matches your distro:
- wayscriber-amd64.deb (Ubuntu, Debian, Linux Mint, Pop!_OS, and other Debian-based distros)
- wayscriber-x86_64.rpm (Fedora, RHEL, Rocky Linux, AlmaLinux, Nobara, and other RPM-based distros)
Optional: install the configurator package (wayscriber-configurator) after wayscriber:
- wayscriber-configurator-amd64.deb
- wayscriber-configurator-x86_64.rpm
- Note: wayscriber-configurator is a separate app and does not install wayscriber.
Launch Wayscriber from your application menu/launcher.
Optional later: switch to daemon mode (preferred) using the steps in Usage.

sudo dnf install wl-clipboard grim slurp       # Fedora

See https://wayscriber.com/docs/ for the latest documentation.

Usage

Daemon Mode (preferred)

Recommended for daily use: faster toggle, better workflow, and session persistence.

Run wayscriber in the background and toggle with a keybind:

systemctl --user enable --now wayscriber.service

No-CLI setup path:

Open wayscriber-configurator
Go to the Daemon tab
Click Install/Update Service, then Enable + Start
Set a shortcut and click Apply Shortcut
- GNOME: writes a GNOME custom shortcut (wayscriber --daemon-toggle)
- KDE/Plasma: writes systemd drop-in env (WAYSCRIBER_PORTAL_SHORTCUT) for portal global shortcuts

Add keybinding:

Hyprland:

bind = SUPER, D, exec, wayscriber --daemon-toggle

Use only one toggle binding. Duplicate SUPER+D entries can fire twice and immediately undo the toggle. If your compositor shortcut environment does not resolve wayscriber from PATH, use the absolute path from command -v wayscriber instead.

Reload your config:

hyprctl reload

GNOME (Ubuntu/Debian/Fedora):

Open Settings -> Keyboard -> Keyboard Shortcuts.
Scroll down to Custom Shortcuts, click +.
Name: Wayscriber Toggle.
Command: wayscriber --daemon-toggle.
Set a shortcut key (recommended on Ubuntu GNOME: Super+G; Super+D is often already in use).

KDE Plasma:

Open Settings -> Keyboard -> Shortcuts.
Add new Command or Script.
Name: Wayscriber Toggle.
Command: wayscriber --daemon-toggle.
Assign a key (for example Meta+Shift+D).

Other desktops/window managers:

Bind wayscriber --daemon-toggle to any global shortcut key you prefer.

Light passthrough controls:

Ctrl+Shift+L is a Wayscriber in-overlay shortcut, not an OS/global shortcut. It works while the overlay is focused.
Once light passthrough is active, normal keyboard and pointer input goes to the app underneath. Bind compositor/global shortcuts to wayscriber --light-toggle and wayscriber --light-draw-toggle for reliable control.
Use wayscriber --light-draw-on on press and wayscriber --light-draw-off on release for draw-while-held shortcuts.

Use --no-tray or WAYSCRIBER_NO_TRAY=1 if you don't have a system tray; otherwise right-click the tray icon for options:

Toggle overlay visibility
Freeze/unfreeze the current overlay
Capture full screen / active window / region
Toggle the help overlay
Flip session resume on/off (writes to config)
Clear saved session data
Open the log folder
Open configurator / open config file / quit

Troubleshooting tray icons:

If the tray icon is blank or the menu shows square placeholders (notably Noctalia/Quickshell), start the daemon with WAYSCRIBER_TRAY_FORCE_PIXMAP=1.

Alternative — use compositor autostart instead of systemd:

exec-once = wayscriber --daemon
bind = SUPER, D, exec, wayscriber --daemon-toggle

Service commands:

systemctl --user status wayscriber.service
systemctl --user restart wayscriber.service
journalctl --user -u wayscriber.service -f

One-Shot Mode (alternative)

Launch wayscriber when you need it, then exit:

wayscriber --active
wayscriber --active --mode whiteboard
wayscriber --active --mode blueprint
wayscriber --freeze   # start with screen frozen

Bind to a key (Hyprland example):

bind = SUPER, D, exec, wayscriber --active

Press F1/F10 for help or Shift+F1 for quick reference. Ctrl+K opens the command palette; F11 opens the configurator; Escape or Ctrl+Q exits.

Screenshot Shortcuts

Shortcut	Action
`Ctrl+Shift+P`	Capture full screen (respects `capture.copy_to_clipboard`)
`Ctrl+Shift+O`	Capture active window (respects `capture.copy_to_clipboard`)
`Ctrl+Shift+I`	Capture selection (respects `capture.copy_to_clipboard`)
`Ctrl+C`	Copy full screen to clipboard
`Ctrl+S`	Save full screen as PNG
`Ctrl+Shift+C`	Select region → clipboard
`Ctrl+Shift+S`	Select region → save PNG
`Ctrl+6`	Region → clipboard (explicit)
`Ctrl+Alt+6`	Region → save PNG (explicit)
`Ctrl+Alt+O`	Open last capture folder

Requires wl-clipboard, grim, slurp (installed automatically by deb/rpm/AUR packages). Falls back to xdg-desktop-portal if missing. Canvas export commands are available in the command palette and keybindings. export_board_pdf_file saves the active board as a multi-page PDF, export_all_boards_pdf_file saves every board in board order, and both PDF actions are unbound by default. PDF exports keep transparent pages blank unless [export.pdf] transparent_background = "desktop" is set, which captures the live desktop behind the overlay for transparent pages only. Use --exit-after-capture / --no-exit-after-capture to override whether the overlay closes after a capture. --about opens the About window.

Getting Help

Help overlay: F1 or F10
Quick reference: Shift+F1
Command palette: Ctrl+K (search monitor or display for output actions)

Arrow labels can auto-number when enabled in the arrow toolbar; reset with Ctrl+Shift+R. Step markers auto-increment and reset from the toolbar (or bind reset_step_markers in config.toml). Preset slots can be saved/cleared from the toolbar; edit names and advanced fields in config.toml. Blur has no default keyboard shortcut; bind select_blur_tool in config.toml if you want direct keyboard access.

Configuration

Config file: ~/.config/wayscriber/config.toml

Create from example:

mkdir -p ~/.config/wayscriber
cp config.example.toml ~/.config/wayscriber/config.toml

Or use the GUI configurator:

wayscriber-configurator   # or press F11

Key Sections

[drawing]
default_color = "red"
default_thickness = 3.0
polygon_sides = 5

[drawing.drag_tools.right]
drag_tool = "pen"
drag_color = "blue"

[presets]
# slot_count: 3-5
slot_count = 5

enable_vsync = true
max_fps_no_vsync = 60
ui_animation_fps = 30

[ui]
# status bar visibility and position

[boards]
# named boards + backgrounds

Session Persistence

Enable via configurator (F11 → Session tab), CLI flags, or the tray checkmark (writes to config).

wayscriber --resume-session      # force resume (persist/restore all boards + history/tool state)
wayscriber --no-resume-session   # disable resume for this run
wayscriber --session-info        # inspect saved sessions
wayscriber --clear-session       # remove stored boards

Notes:

When restore_tool_state is enabled (default), the last-used tool settings (including arrow head placement) override config defaults on startup. Disable it in the Session tab or clear the session to force config values.

Tablet/Stylus Support

Tablet support (zwp_tablet_v2) ships in default builds and is enabled at runtime by default:

[tablet]
enabled = true
pressure_enabled = true
min_thickness = 1.0
max_thickness = 8.0

It works out of the box in default builds. Set [tablet].enabled = false in config.toml to opt out. To build without tablet support: cargo build --release --no-default-features (or remove the tablet-input feature).

See https://wayscriber.com/docs/ for the full reference.

Troubleshooting

Daemon not starting after reboot

User services don't start at boot by default. Enable lingering:

loginctl enable-linger $USER

Or use compositor autostart instead:

exec-once = wayscriber --daemon

Service won't start

systemctl --user status wayscriber.service
journalctl --user -u wayscriber.service -f
systemctl --user restart wayscriber.service

Overlay is blurry/non-transparent on KDE Plasma

If the overlay appears blurry instead of transparent on KDE Plasma:

Cause: The "Better Blur DX" effect (or similar blur effects) may blur wayscriber's transparent overlay.

Solution (Option 1 - Configure Better Blur DX):

Open System Settings → Window Management → Desktop Effects
Click the configure button next to "Better Blur DX"
Go to the Force Blur tab
Add wayscriber to the window class list
Make sure Blur all except matching is selected
Click Apply

Solution (Option 2 - Use standard blur):

Disable "Better Blur DX" in Desktop Effects
Enable the standard "Blur" effect instead

Note: To find wayscriber's window class:

sleep 2; qdbus org.kde.KWin /KWin queryWindowInfo | grep resourceClass

Then open wayscriber before the sleep ends.

Overlay not appearing

Verify Wayland session: echo $WAYLAND_DISPLAY
Ensure compositor supports wlr-layer-shell
Run with logs: RUST_LOG=info wayscriber --active

Config issues

ls -la ~/.config/wayscriber/config.toml
RUST_LOG=info wayscriber --active   # watch for TOML errors

Environment variables

Common toggles:

WAYSCRIBER_TOOLBAR_DRAG_PREVIEW=0 disables inline toolbar drag preview (default: on)
WAYSCRIBER_TOOLBAR_POINTER_LOCK=1 enables pointer-lock drag path (default: on)
WAYSCRIBER_TOOLBAR_DRAG_THROTTLE_MS=12 throttles toolbar drag updates (default: 12; set 0 to disable)
WAYSCRIBER_DEBUG_TOOLBAR_DRAG=1 enables toolbar drag logging (default: off)
WAYSCRIBER_DEBUG_TOOLBAR_COLOR=1 enables toolbar color picker logging (default: off)
WAYSCRIBER_FORCE_INLINE_TOOLBARS=1 forces inline toolbars on Wayland (default: off)
WAYSCRIBER_NO_TRAY=1 disables the tray icon (default: tray enabled)

See docs/CONFIG.md for the full list.
