Just a post on how well it runs on this specific piece of kit.
ThinkPad T14 AMD (first gen)
AMD Ryzen 7 Pro 4750u
Integrated Radeon Graphics (Renoir)
Wifi 6 AX200
USB ports work.
HDMI out works.
Hardware acceleration works. Dark Souls ptde under proton 5.13-6 plugged in, tlp disabled runs at a similar performance as windows. graphical glitches and hiccups appear to be proton related but it's difficult to say.
HeadPhone jack works for output not for input.
Ethernet has 2 ports, I believe this is a quirk of the hardware not Linux. Works only if ethernet was plugged in before boot. No hotswap.
OS fn keys work. vol mute, vol inc, vol dec, mute mic, inc bright, dec bright and network kill (note: network kill only kills, must manually re-enable through gui).
Could not test weird dock thing... inconclusive.
Don't own USB C device... inconclusive.
Mic light is constantly on with no relation to actual mic volume.
Built in Mic is very quiet.
Occasional temporary lock up on wake-up. I believe this is related to tlp and not the base OS. Unfortunate as tlp is pretty much a necessity as the base OS is power hungry. With tlp: 8-9 hour battery, Without tlp: 4-5 hour battery (tested with web-browsing/office work. intensive work not included).
Stutter on log in. only during actual wake-up and actual log-in, the login gui itself is responsive once it gets started.
Most of the issues I've encountered are most likely related to the use of an older LTS kernel. If you need Everything to work right away then consider a rolling release in the meantime. If you can live with the issues Zorin OS 16 works nicely enough.
