CPU & GPU Monitor is a Cinnamon desklet with compact history graphs for:
- aggregate CPU usage;
- RAM usage;
- CPU temperature;
- NVIDIA GPU utilization;
- VRAM usage;
- GPU temperature.
The first public version targets Linux and Cinnamon. CPU temperature uses the
standard Linux hwmon interfaces exposed by AMD k10temp or zenpower, with a
constrained CPU/package thermal-zone fallback. NVIDIA metrics use the first row
returned by the system-provided nvidia-smi command.
Intel CPU temperature support is not claimed. AMD GPUs and Intel GPUs are not supported, and multi-GPU selection is not implemented. This is not a claim of support for every AMD CPU or NVIDIA GPU.
If nvidia-smi is absent or unavailable, the GPU section reports a degraded
state while CPU and RAM monitoring continue. A working nvidia-smi is normally
provided by the NVIDIA driver/package managed by the Linux distribution or
system; the desklet does not download external software.
The settings panel provides the update interval, UI scale, legend visibility, and separate colors for CPU/GPU utilization, memory, and temperature lines.
The standard Cinnamon Spices installation path is System Settings → Desklets → Download, followed by enabling the desklet from Manage. No custom installer or external download is required.
The initial release was live-tested on Cinnamon 6.6.9/X11 with an AMD Ryzen 5
5600H, its k10temp Tctl sensor, and an NVIDIA RTX 3050 Laptop GPU using
nvidia-smi. Other hardware and Cinnamon versions remain unverified.
