Here’s a more specific list:
Wifi
Bluetooth
Fingerprint Scanner (not including hardware issue of erasing old fingerprint scans)
Sleep / Suspend - I did a brief test of s2idle vs. deep and saw no difference, although deep still takes ~15s to wake. Maybe someone that knows more about this issue than I do should test further?
Fractional Scaling - I don’t use it, but it was not available as a default option in Gnome 41. I guess it’s still “experimental”?
Mic in via Headphone Jack - I honestly didn’t know this was an issue, but I just tested it and sure enough it does NOT work.
I’ve revised my original post to read nearly everything.
