What CPU-X is

CPU-X is free and open source system profiling and monitoring software for GNU/Linux and FreeBSD. It gathers information about the processor, motherboard, memory, system, graphics card, and performance. The project offers a GTK graphical interface, an NCurses text interface, and a command-line dump mode. It supports 32-bit and 64-bit x86 and ARM processors. Listed distribution options include packages for several Linux distributions and FreeBSD, a portable AppImage, and a Flatpak on Flathub. Starting the daemon can expose special devices for additional information; that daemon requires root privileges and uses Polkit for privilege escalation. CPU-X is maintained by The Tumultuous Unicorn Of Darkness and is licensed under GPL-3.0. The maintainer announced the project’s end on September 27, 2026, with the repository being archived because newer CPU generations were not properly detected. The README also says new issues are not accepted.
