What TuxClocker is

TuxClocker is a free GNU/Linux program for monitoring and controlling computer hardware. It combines a D-Bus daemon with a Qt graphical interface and supports any number of devices at once. Users select a device node to read or change its properties. NVIDIA tools include fan control, clock and power-limit adjustment, temperature and utilization readings, and VRAM monitoring; voltage settings and readings are available for 600–900 series GPUs under Xorg. AMD features include fan and clock control, performance parameters, voltage and VRAM monitoring, and voltage-frequency curve editing on applicable GPUs. CPU functions cover frequency and utilization monitoring, governor settings, frequency limits, power-use monitoring, and energy-power preferences. The project offers a prebuilt tarball from its release page and packages for openSUSE Tumbleweed. NVIDIA editing requires Coolbits, while AMD editing requires the amdgpu.ppfeaturemask boot parameter. Optional dependencies connect vendor support, and translations can be contributed through Weblate or local pull requests. The project uses GPL-3-only licensing and lists GNU/Linux as its current platform focus.

Getting started

Visit the TuxClocker GitHub project page.
Download the prebuilt tarball from the release page, or use the openSUSE Tumbleweed package.
Set Coolbits before editing NVIDIA hardware, or the amdgpu.ppfeaturemask boot parameter before editing AMD hardware.
Use the Qt interface to select a device node and inspect or change its properties.

Verdict

TuxClocker brings hardware readings and controls into one daemon-and-GUI program, with features varying by GPU vendor and device. Check the stated prerequisites before relying on its editing controls.
