System76 has released COSMIC System Monitor, a lightweight tool built specifically for COSMIC Desktop that shows real-time CPU, memory, disk, network, GPU, and process details—plus quick Quit and Force Quit options. It’s polished enough to leave many users rel
On a good day, you barely think about what your computer is doing. Then something stutters, fan noise spikes, or apps start behaving like they’re chewing through resources—and suddenly you want answers fast.
System76’s new COSMIC System Monitor is designed for exactly those moments. Built specifically for the COSMIC Desktop, it’s meant to deliver real-time system metrics without the “slow, bulky, or cluttered” feel of other options.
Linux users have plenty of ways to check what’s happening: GNOME System Monitor. Plasma System Monitor. MATE System Monitor. Mission Center. Conky. Resources. Stacer. Htop. Glances. and more. COSMIC System Monitor is positioned as a simpler alternative that integrates tightly with the desktop it’s made for.
COSMIC System Monitor monitors what you’d expect in a modern system dashboard. It tracks applications and processes, shows process utilization per core, and displays CPU usage and memory usage. It also covers disk usage. network download and upload speeds. GPU information including GPU temperature. and the kinds of details that help you pinpoint what’s responsible when the system starts acting up. The interface is designed so you can click into sections to expand the view.
By default, users see a widget displaying CPU usage. Clicking “Details” expands the information, including process utilization per core. The same pattern shows up in other areas—clicking Memory reveals swap usage, so you can quickly see whether memory pressure is part of the problem.
In the Details section for each widget, the tool surfaces additional specifics:
Network shows receiving and sending usage for all attached network cards. Disk includes read/write speeds, processes, and temperature. GPU shows GPU utilization, GPU VRAM, and processes. Processes list PID, CPU, Memory, GPU, GPU VRAM, Disk, and Priority. Applications show User, CPU, Memory, GPU, GPU VRAM, and Disk.
If you need to act—not just observe—the monitor also includes process management. From the Processes widget. you click “Details. ” locate the process tied to an application. and choose either Quit or Force Quit. “Force Quit” is treated as a serious lever. with the recommendation to use it only when you’re sure a process needs to go away.
There’s also a Settings feature in COSMIC System Monitor, but customization is limited. Users can only change the theme, with options to “Match desktop,” Dark, or Light.
For some Linux users, that level of integration is the whole point. The author behind this hands-on view says they’re not the “process/data fanatic” they used to be. They once kept Conky running on their desktop for quick visibility into system resources. but these days they mostly open a system monitor only when something goes wrong.
That’s why COSMIC System Monitor’s design lands: it’s easy to leave open on a secondary monitor. and it honors the system theme set in COSMIC—so it doesn’t look out of place when it’s constantly in your line of sight. In practice, the author describes turning their head to a monitor and getting the information they need without extra effort.
There’s one catch, and it matters if you don’t already live in the COSMIC world. The tool is built specifically for COSMIC Desktop. and while it can be installed on other distributions. the process is not exactly easy. The steps described are: install Rust, cargo, just, and several development libraries, clone the repository, and then build and install. The conclusion is blunt: it’s not worth that trouble.
If System76 keeps making tools that feel this “helpful and elegant,” the author says they can’t imagine leaving Pop!_OS and COSMIC Desktop.
