HeadsUp-Fast

A trivial alternative to Ubuntu's landscape-info with no external dependencies, that runs in 10% of the time of /etc/update-motd.d/50-landscape-sysinfo. Because perf matters.

Originally forked from landscape-sysinfo-mini. Changes include removing utmp dependency and generally speeding things up.

Features

• Fast: Runs in ~10% of the time of the standard Ubuntu landscape-sysinfo
• Zero dependencies: Pure Python 3.6+ with standard library only
• Linux-focused: Designed specifically for Linux systems with /proc filesystem
• Drop-in replacement: Easy to replace Ubuntu's default MOTD script

Sample Output

  System information as of Wed Sep 18 15:04:32 2025

  System load:  12.5%              Processes:        145
  Usage of /:   67.2% of 29.84GB   Users logged in:  2
  Memory usage: 41.3%              IP address for eth0: 192.168.1.100
  Swap usage:   2.1%

Installation

Option 1: Install as a command

pip install headsup-fast

Then run:

headsup

Option 2: Replace Ubuntu's default MOTD (recommended)

1. Copy the script to your motd directory:

   sudo cp headsup.py /etc/update-motd.d/50-headsup
   sudo chmod +x /etc/update-motd.d/50-headsup
   

2. Remove the standard Ubuntu one (optional):

   sudo rm /etc/update-motd.d/50-landscape-sysinfo
   

3. Test it:

   sudo run-parts /etc/update-motd.d/
   

Requirements

• Linux system with /proc filesystem
• Python 3.6 or higher
• Standard Linux utilities: ip, who

Performance

This implementation focuses on speed by:

• Using /proc filesystem directly instead of external tools where possible
• Avoiding heavy dependencies like python-utmp
• Efficient parsing and minimal subprocess calls
• Optimized string formatting
