HardScope

A Speccy-style hardware monitor for Linux — built natively for Fedora with GTK4 / libadwaita. It shows your CPU, motherboard, memory, graphics, storage and live sensor readings (temperatures, fan speeds, voltages) in a clean sidebar layout.

Features

• Summary — one-glance overview of the whole machine
• CPU — model, cores/threads, live per-core usage + frequency, package temp
• Memory — usage, swap, and physical DIMM details (with sudo)
• Graphics — each GPU's model, temperature, utilisation, VRAM
• Storage — drives (model/size/bus/SMART health), NVMe temp, filesystem usage
• Sensors — every hwmon chip: temperatures, fans (RPM), voltages — live
• Fan Control — switch the firmware thermal profile (cool / quiet / balanced / performance via ACPI platform_profile) and watch live RPM per fan. Changing the profile needs root, so the app asks for your password once per session (via pkexec). Note: most laptops (incl. Dell dell_smm models) let the BIOS own the fan curve, so exact RPM/percent cannot be set from Linux — the profile is the real lever.
• Network — interfaces, IP/MAC, link speed, traffic counters
• System — OS, kernel, motherboard, BIOS, uptime

Live values refresh every 1.5 s. All readings come straight from the kernel (/proc, /sys/class/hwmon, /sys/class/dmi) plus psutil, so it works without any daemon.

Requirements

The whole stack ships with a default Fedora 44 Workstation. If anything is missing:

sudo dnf install python3-gobject gtk4 libadwaita python3-psutil \
                 pciutils util-linux dmidecode smartmontools

Run

cd hardscope
python3 -m hardscope        # or:  ./run.py

Some details need root and otherwise show as needs root / —:

• DIMM details (manufacturer, speed, slot) via dmidecode
• SMART health of SATA drives via smartctl

To see them, launch with privileges:

sudo python3 -m hardscope

Headless / data-only

The engine runs standalone and dumps everything as JSON — handy for scripting or debugging:

python3 -m hardscope.hardware | jq .

Install a desktop launcher

cp io.github.hardscope.HardScope.desktop ~/.local/share/applications/
# edit Exec= to an absolute path if you didn't put hardscope on PYTHONPATH

Architecture

File	Role
hardscope/hardware.py	Reading engine — all kernel/sysfs/tool access. No UI. Split into read_static() (slow, once) and read_dynamic() (cheap, per tick).
hardscope/window.py	GTK4 window: sidebar + per-category panels, live refresh timer.
hardscope/__main__.py	Adw.Application entry point.

The UI never touches sysfs directly — it only consumes the dicts the engine returns, so the two layers can evolve independently.

Roadmap ideas

• Live history graphs (temperature / usage sparklines)
• Export a full report to text/HTML (a signature Speccy feature)
• System-tray temperature indicator
• NVIDIA proprietary-driver support via NVML (currently uses nouveau hwmon)
• Per-process resource view
