FSM — Swiss Army Knife for Linux hardware diagnostics

FSM is a simple system profiler for modern Linux distributions. It is a program that displays information about a computer's software and hardware. It is designed for modern Linux systems.

Actual FSM version: .

another package types here.

Compatible with Debian version 11 and later, Ubuntu version 22.04 and later, and Fedora 42 and later. It may also work with other Linux distributions released in 2022 or later.

System Passport

The FSM interface is divided into two part: the left side of the window contains a sidebar with options for selecting which page to display, while the right side displays the actual content associated with that page. The home page is System Passport (Dashboard), which displays key system information in the form of cards. Clicking on each card opens the corresponding page with more detailed information. The home page is designed to provide an overview of the system's current status.

Simple information representation

Unlike Hardinfo and similar tools, FSM displays almost everything in the form of table-based panels. Many tables are dynamically updated as the metrics they contain change. You can copy text from these tables — click on the desired cell to copy its contents to the clipboard.

Modern technologies support

The development of FSM has focused on supporting modern technologies. The program can display a list of systemd services currently running. Integration with this system manager is still far from complete — I plan to add a number of additional systemd-related features in the near future. However, this does not mean that FSM is strictly dependent on systemd; it can also run on systems without it. Furthermore, FSM is one of the few programs capable of displaying UEFI settings.

CPU and RAM utilization charts

To access the system's health over time, use the CPU and RAM utilization charts. They are updated in real time. At the bottom of each chart is a legend with color-coded indicators: white text indicates normal usage, yellow indicates high but not critical usage, and red indicates resource usage exceeding 95%.

System requirements

• OS: modern Linux with glibc >= 2.36, Xorg or Wayland, and, optionally, dbus and systemd.
• CPU architecture: amd64, i386 or aarch64 (ARM-v8-A).
• RAM: 512 Mb
• Free disk space: 500 Mb

⚠️ TROUBLESHOOTING ⚠️

FSM Portable (AppImage) displays an error when opening the DMI, Kernel Modules, or Firmware pages

Error text:

[ferrix-polkit] Non-zero return code:
ERROR: ld.so: object 'libapprun_hooks.so' from LD_PRELOAD
cannot be preloaded (cannot open shared object file): ignored.
Error executing /home/${USER}/.local/bin/ferrix-polkit:
    No such file or directory

To fix this error, download the correct ferrix-polkit and place it in the appropriate directory:

wget https://github.com/mskrasnov/FSM/releases/download/v0.7.1/ferrix-polkit
chmod +x ./ferrix-polkit
mkdir -pv ~/.local/bin
mv -v ./ferrix-polkit ~/.local/bin/

Support development

I'm developing this program on my own in my free time between studying and working, without reveiving any payment for it. If you like my program or want to thank me, you can contribute whatever you can to its development and support by sending any amount to Boosty or to my bank card (if you're from Russia).
