Mission Center, the popular Linux system monitor and task manager app, released new 1.1.0 version today.

The new release of this free open-source app improved CPU monitoring support. It can now display the amount of electrical energy that CPU consumes in watts.

It works by reading /sys/class/powercap/intel-rapl*/energy_uj for CPU power draw. The file is however unreadable by default for security reason. Meaning user needs to grant read access permission by running the command below in terminal:

sudo chmod a+r /sys/class/powercap/intel-rapl*/energy_uj

For AMD, the feature request page does not mention AMD processors, and I don’t have a AMD CPU to try it out.

The app also overhauled the Services page. The services are now grouped into “User Services” and “System Services”. And, it supports filtering services on Running, Failed, Stopped, and/or Disabled status.

As well, it now supports view child processes (if any) for services, and allows to send signal (e.g., Suspend, Continue, Hangup, Interrupt, Terminate, and Kill) by right-clicking on a process.

Besides that, it added new “About System” dialog that can be launched from the hamburger menu, which displays the name and version info of Linux Distribution, package manager, Kernel, and desktop environment.

Other changes in Mission Center 1.1.0 include:

• Improve Fan backend and configurations.
• Reduce CPU usage.
• Fix AMD Radeon RX 6600 GPU shown up.
• Fix missing Vulkan and OpenGL information in GPU page.
• Fix missing shared memory usage on the memory graph.
• Add keyboard shortcut to start service.
• Update to GNOME 49, and the latest NVTOP.
• Add donation to Flatpak and Readme.

For more about this version, see the official release note in Gitlab.

For Ubuntu (with either AMD/Intel or ARM processor), the app is available to install as Snap package through the App Center for 24.04+ or Ubuntu Software or 22.04 and earlier.

For most Linux Distributions, the app is also available to install as Flatpak packages on either amd64 or arm64 platforms.

Linux Mint and Fedora (with 3rd party repository enabled) may search & install the Flatpak package from either Software Manager or GNOME Software. While others may do the following steps one by one to install it:

Uninstall:

To uninstall the Snap package, use either App Center or Ubuntu Software.

And, to uninstall the Flatpak, run command:

Optionally, run flatpak uninstall --unused to remove useless runtimes.
