EWC - Experimental Wayland Compositor

Wayland compositor from scratch in Rust.

• No wlroots or smithay.
• No libwayland.

Roadmap

• Enough to run foot, alacritty and mpv.
• Sowfware (pixman) renderer.
• OpenGL renderer.
• Nested wayland backend.
• Basic single-output drm/kms backend.
• Basic dynamic window management (master-stack layout).
• Full wayland.xml conformance (minus deprecated wl_shell).
• Full xdg-shell.xml conformance.
• Yes/no damage tracking.
• Full damage tracking.
• Direct scan-out support.

Supported protocols

• wayland.xml (partial)
  • DnD
  • wl_output
• xdg-shell.xml (partial)
  • Qt popups don't work (but GTK does)
  • Proper popup positioning
  • Popup dismissal
• linux-dmabuf-v1.xml (v3, when using GL renderer)
• viewporter.xml
• single-pixel-buffer-v1.xml
• cursor-shape-v1.xml
• wlr-layer-shell-unstable-v1.xml
• fractional-scale-v1.xml

Environment variables

• EWC_NO_GL=1 to force software renderer.

Configuration

Config file is located at $XDG_CONFIG_HOME/ewc/config.toml or ~/.config/ewc/config.toml.

The default config is

# RGB color of the background
bg_color = [0.2, 0.1, 0.2]

# See `man xkeyboard-config`
xkb_layout = "" # System's default layout
# xkb_options = not set - i.e. the default options apply

# Example of a pointer config
#
# [pointer.'1267-12541-ELAN071A:00_04F3:30FD_Touchpad']
# tap_to_click = true
# natural_scroll = true
