Enhancement possibility: support graphics freq/power

[mikehardy]

I noticed with the Intel power gadget they can do the built-in intel GPU information as well, would be neat if s-tui could also access it: https://software.intel.com/en-us/articles/intel-power-gadget-20

Separately, the Intel power gadget doesn't handle it but if there was an option to handle discrete graphics (for laptops that have a discrete GPU) it would be extra cool if it could monitor those also

I'll take a look at adding Intel GPU metrics, other GPU solutions might require a different approach, as it varies a lot between AMD/Nvidia

conky can display - if configured and you have the right things installed - an example from here https://askubuntu.com/a/1020887/858118

This would be really great addition and maybe not so hard to implement using conky example.

This is definitely on the road map. The next milestone is to enable per-core view of the metrics. This will lead to many changes in the current code base. Once it is implemented, it should be easier to add support for a graphics card, and hopefully, multiple graphics cards as well.
