TopHat is an elegant system resource monitor for the GNOME shell. It displays CPU, memory, and network activity in the GNOME top bar.
Install TopHat from the GNOME Shell extensions page.
Most Debian-based systems (including Ubuntu and Pop!_OS) will also need 'gir1.2-gtop-2.0' to be installed. Usually this means running the command sudo apt install gir1.2-gtop-2.0.
- GNOME 3.32 or newer
- The gtop system monitoring library (e.g., 'libgtop' on Debian-based systems, likely already installed as part of GNOME)
- GIRepository (gir) bindings for the gtop system monitoring library (e.g., 'gir1.2-gtop-2.0' on Debian-based systems)
The latest release of TopHat has been tested on the following systems:
- CentOS Stream 8
- CentOS Stream 9
- Debian 11.4
- Fedora 36
- Pop!_OS 22.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 22.10 (Preview)
See RELEASES.md for the list of fixes and new functionality included in each release.
