Dual Monitor Script

#!/bin/bash
INTERNAL="eDP-1"
EXTERNAL="HDMI-1-0"

if xrandr | grep "^$EXTERNAL connected" >/dev/null; then
    xrandr --output $INTERNAL --auto --primary --output $EXTERNAL --mode 3840x2160 --scale 2x2

EXT_MON=$(xrandr | grep " connected " | grep -v "eDP" | cut -d' ' -f1)
if [ -z "$EXT_MON" ]; then
    xrandr --output eDP-1 --auto --scale 1x1 --primary
else

Collapsible Tips & Warnings

• Run sysrefresh before building AOSP.
• Use ncdu or df -h for disk monitoring.
• Check emulator status with run_aosp_emulator.sh status.
• Ensure external monitor is connected before running monitor scripts.
• Keep script backups in ~/scripts/.

• Do not run multiple monitor automation scripts simultaneously.
• Wayland may not reliably support external monitors; use Xorg if needed.
• Java 11 must be installed and active for AOSP builds.
• Do not modify scripts in /usr/local/bin without proper permissions.
