# Wayland configuration for MageDok 7" touchscreen display
|
|
# Used by Cage Wayland compositor for lightweight kiosk mode
|
|
# Replaces X11 xorg-magedok.conf (used in Issue #369 legacy mode)
|
|
|
|
# Monitor configuration
|
|
[output "HDMI-1"]
|
|
# Native MageDok resolution
|
|
mode=1024x600@60

# Position (primary display)

position=0,0

# Scaling (no scaling needed, 1024x600 is native)

# Touchscreen input configuration
|
|
[input "magedok-touch"]
|
|
# Calibration not needed for HID devices (driver-handled)
|
|
# Event device will be /dev/input/event* matching USB VID:PID
|
|
# Udev rule creates symlink: /dev/magedok-touch

# Performance tuning for Orin Nano

# Wayland buffer swaps (minimize latency)

# Double-buffering for smooth animation

|
|
|
|
# Notes:
|
|
# - Cage handles Wayland protocol natively
|
|
# - No X11 server needed (saves ~100MB RAM vs Xvfb)
|
|
# - Touch input passes through kernel HID layer
|
|
# - Resolution scaling handled by Chromium/browser
