I took the plunge on the AMD CPU/GPU legion s7! There are caveats on this system, most notably the speakers don’t output at all 
the headphones work. I can see activity in pavuctl but there is no sound from the speakers. It’s a known problem, I saw some discussions on bugzilla after the fact. Apparently it could be fixable if it is implemented in kernel, who knows when.
There are a couple of other hickups:
-
brightness key stop working after suspend, although I can change brightness using the slider on top right gnome menu, figure out why…?!
-
wifi doesn’t work on lts kernel (no wifi at all, neither in the settings), works only on recent kernel. One caveat is that if I have a USB stick in there and suspend or logout/restart, wifi disappears entirely. Need to reboot to make it work.
Everything else works smoothly for now, trackpad, Bluetooth, fan/cooling etc. It’s a fantastic machine, cools nicely. Still need to test graphics and gaming. But considering the other bugs they add up. I have 15 days to bring it back.
At this point wondering if I am better off doing this and get a system 76 oryx pro. Or need more patience that things eventually will be fixed in the kernel if at all, since it’s a new model.
The downside is that system 76 only have AMD cpu with Nvidia GPU, and want to avoid Nvidia this time around. But ory pro also looks solid, but poor battery life and only 1080 screen.
Edit: might make a separate thread but the problem is similar to here:
https://bugzilla.kernel.org/show_bug.cgi?id=208555
The driver should be ALC3306 but Alsa says it’s ALC 287. That will be very tricky to fix on my own, according to all the posts I read it’s really a thing that needs to be fixed upstream either in the kernel or some bios value from Lenovo.
