System

The System menu provides core configuration options that control system identity, localization, power behavior, notifications, time synchronization, and network proxy settings.

The System menu is located under:

Settings → System Configuration → System

These settings affect global system behavior and should be configured carefully.

Example:

System Configuration

General System Settings​

Hostname​

Defines the system hostname.

Default:

  • MOS

Notes:

  • Used for network identification
  • Changes may require reconnecting to the system UI

Keymap​

Defines the system keyboard layout.

Default:

  • de-latin1-nodeadkeys

Use cases:

  • Console access
  • Local keyboard input

Timezone​

Defines the system timezone.

Default:

  • Europe/Vienna

Notes:

  • Affects logs, cron jobs, and scheduled tasks
  • Should match the physical system location

CPU Governor​

Defines the CPU frequency scaling policy.

Default:

  • ondemand

Common options:

  • ondemand – Dynamic scaling based on current system load
  • performance – Forces maximum CPU frequency
  • powersave – Forces minimum CPU frequency to reduce power consumption
  • conservative – Gradual frequency scaling with slower ramp-up, optimized for power efficiency

Recommendation:
Use ondemand for balanced performance and efficiency.

Global Spindown (minutes)​

Defines the idle time before disks are spun down.

Default:

  • 20 minutes

Notes:

  • Reduces power consumption and noise
  • Excessively low values may increase disk wear

Persist History​

  • Enable / Disable

Controls whether command and system history is preserved across reboots.

Use cases:

  • Enable for auditing and troubleshooting
  • Disable for privacy-focused or minimal systems

Display Settings​

Powersave​

Controls display power-saving behavior.

Default:

  • Enabled

Powerdown​

Defines the time before the display is powered down.

Default:

  • 60 minutes

Timeout​

Defines the inactivity timeout for the user interface.

Default:

  • 30 minutes

Notification Sounds​

Controls system notification sounds.

Sound on Reboot​

  • Enable / Disable

Sound on Shutdown​

  • Enable / Disable

Sound on Startup​

  • Enable / Disable

Notes:

  • Useful for local systems
  • Can be disabled for headless or silent environments

NTP (Time Synchronization)​

NTP Enabled​

  • Enable / Disable

Enables or disables network time synchronization.

NTP Mode​

Defines the NTP synchronization mode.

Default:

  • iburst

Note:
iburst allows faster initial synchronization.

NTP Servers​

Defines the NTP servers used for time synchronization.

Default servers:

  • 0.pool.ntp.org
  • 1.pool.ntp.org

Notes:

  • Additional servers can be added
  • Custom or local NTP servers are supported

Proxy Settings​

Defines global proxy configuration for outbound network traffic.

HTTP Proxy​

Defines the HTTP proxy server.

HTTPS Proxy​

Defines the HTTPS proxy server.

FTP Proxy​

Defines the FTP proxy server.

No Proxy​

Defines addresses or domains that bypass the proxy.

Examples:

  • localhost
  • 127.0.0.1
  • .local

Summary​

The System menu centralizes essential configuration options that affect the entire OS.

Key areas covered:

  • System identity and localization
  • Power and performance behavior
  • UI display and notification settings
  • Time synchronization via NTP
  • Network proxy configuration

Correct system configuration is critical for stability, performance, and predictable behavior.
