I like to use conky as a real-time monitor for both CPU and GPU. Installation is straightforward:

sudo apt install conky

Intel i7-6700HQ iGPU HD 530

In this instance Iโ€™ve booted using the integrated GPU rather than the nVidia GTX 970M:

The conky code adapts depending on if booted with prime-select intel or prime-select nvidia:

nVidia GPU GTX 970M

Conky code

The conky code was recently modified to auto-sense the GPU. Now it doesnโ€™t have to be hand modified when rebooting to a different GPU:

# Intel iGPU |
