LordOS

Raspberry Pi 5 · Raspberry Pi 500

A full desktop on your Raspberry Pi

LordOS draws its desktop on the Pi's GPU, decodes HEVC video in hardware, drives the fan and knows the Argon ONE V5 case by name. One image for both boards, written with LordOS Imager.

The Argon ONE V5 case, supported

LordOS finds the case on the first boot and asks you once. After that, Settings → Cooling drives its blower with LordOS's own fan service, and its front USB ports and audio jack work. No vendor scripts.

  • Quiet by design: the aluminium body is a big heatsink. With Balanced, the fan stayed off at 50–53 °C under a full four-core load.
  • When it's needed: 2,700 RPM at 30 %, 4,500 at 55 %, up to 7,400 at full speed.
  • Front ports: two USB 2.0 ports, microphone and headphones, on after you pick the case in Settings and restart.
  • Safe: LordOS never changes the bootloader's power settings.

Measure your Pi with LordBench

LordOS comes with its own benchmark. It waits for a quiet system, measures the CPU, memory, GPU, the compositor and video, and compares your board with our reference Raspberry Pi 5.

  1. In the app

    Open System Information → Performance and press Quick test (under a minute). The Full test adds the disk, every video codec and a few minutes of load on all cores: 4 to 6 minutes, with some wear on an SD card.

  2. In the terminal

    Run the same tests over SSH, also as JSON:

    lordos-sysreport bench --quick
    lordos-sysreport bench --full --json
  3. Share it

    Post a screenshot of the Performance tab on r/LordOS, or paste the JSON in a hardware report, with your board, case and power supply. That is how we see where LordOS is fast and where it isn't yet.

Four tools in the terminal

They come with LordOS, work over SSH too, and never send anything on their own.

lordos-fetch

The crown and a one-screen summary: version, board, kernel, display, CPU, GPU, memory, disk and isolation. --share hides your user and computer names for a screenshot.

lordos-issue

A complete report for a bug or a hardware test: devices, drivers, displays, signed code, failed services and this boot's errors. Names and addresses are replaced; it only reads, and saves a file you check before posting.

lordos-sysreport

System Information from a terminal: report for the hardware, and bench --quick or --full for LordBench, the same measurements as the app, also as JSON.

lordos-testbench

A test card in a window: frames a second and frame times, every key lit as you press it, the mouse and its wheel, and what the display server reports. Handy to check a new keyboard, mouse or screen.

Tried LordOS on your Pi? Tell us

Every report helps the next person: which board, which case, which screen, what worked. LordOS writes the report for you, with names and addresses removed, and changes nothing.

lordos-issue --print

Or open System Information → Compatibility and share it from there.
