Summary

This PR fixes issues in the XFCE Docker container where users were being prompted for passwords on startup and when the system attempted to sleep/lock. It also changes the default password from "password" to "cua" for consistency.

Changes

Password Configuration

• Changed user password from password to cua (Dockerfile:73)

Power Management & Lock Screen Prevention

• Removed xfce4-goodies meta-package to prevent power manager plugin from loading
• Removed power manager and screensaver packages:
  • xfce4-power-manager and related components
  • xfce4-screensaver
  • light-locker
  • xscreensaver
• Added xfce4-power-manager.xml config to disable all power management features:
  • DPMS (display power management)
  • Screen blanking
  • Inactivity timeouts
  • Lock on suspend/hibernate
• Updated xfce4-session.xml to disable screensaver and screen locking
• Added autostart disabling for screensaver and power manager services

Testing

The container should now:

• Not prompt for password on first login
• Not prompt for password when system tries to sleep
• Not display "Power Manager Plugin unexpectedly left the panel" error
• Use password "cua" for sudo operations
• Never lock the screen or enter sleep mode
• Display the panel correctly with all default elements
