I want to buy used laptop with rx6600m and r7 5800h
Does switch between discrete gpu and apu work on linux for amd gpus?
Maybe there are some pitfalls?

    AMD gpus used to be very bad, but improved a lot in the last 2-3 years. I doubt you’ll have any issues these days.

      I’ve had 3 laptops with AMD GPUs in the past - including the last one I still own that use in my shop - and my personal experience so far with Linux is that I’m about ready to kill someone: the machines are unstable, the displays get corrupted, they don’t wake up from sleep…

      This last AMD GPU laptop I have (Vega 6 chipset) needs rebooting on a regular basis, and only kind of works okay with an older 5-series kernel.

      Having said that, all the bad experiences I’ve had with AMDGPU were with machines older than 3 years. If you say the hardware has improved, I’m glad to hear that. But one thing is for sure: the latest driver is just as buggy and unreliable as it ever was on older hardware.

      Maybe newer chipsets with newer drivers now work well. But you know what? I swore I’d never EVER get another machine that requires amdgpu.ko. I’ll go Intel graphics, it’s just safer.
