Kubuntu on Framework 16 AMD 7000 series here. Sleep is horrible - definitely drains your battery. Bag heats up, and I estimate maybe a 1% drain per hour. I’ve enabled hibernate though I rarely use it.
Battery is alright but not great. I get maybe 2-3 hours of active, light use from full battery.
No compatibility issues that I’ve noticed, though, of course, Linux has its fair share of minor non-hardware-related bugs.
Camera is serviceable but not amazing. Not sure about microphone but I assume the same thing. Speakers are somewhat odd in that the speakers are pointed to the side rather than toward the front, but again - serviceable.
Yes, I don’t use the external GPU. I just use the AMD APU. Also I realized that AMD 7000 could refer to both the cpu and the GPU. Ah, AMD and their marketing
