Note: this is an ongoing process which I'm documenting here. Semi-experimental, but this is my daily driver machine since September 2021 (work included), so I'm aiming for stability (hence why I'm not using the recommended Fedora 39 Beta).

Upgraded from an Intel i7-1165G7 to AMD 7080U mainboard:

• 64GB (2x32GB) G.Skill F5-5600S4040A32GX2-RS
  • Have an SK Hynix 16GB (2x8GB) 4800MHz (HMCG66MEBSA095N BA) kit that I'll test just to see power draw difference.
• SK hynix Gold P31 2TB PCIe NVMe Gen3 M.2 2280

These notes are for Fedora 38 6.5.8-200.fc38.x86_64 with SwayWM.

Booted into Fedora with BIOS 3.02 and seemed fine. First thing I did was upgrade to 3.03.

Decrypt LUKS volumes with a TPM on Fedora Linux

This guide allows you to use the TPM on your computer to decrypt your LUKS encrypted volumes. If you are worried about a cold boot attack on your hardware please DO NOT use this guide with your root volume!

Preflight Checks

Verify that you have a TPM in your computer:

Fedora35 hibernation

This guide helps to configure the hibernation on a default Fedora35 (also worked fine in previous Fedora34) installation by using a swap file. The Fedora35 installation comes with btrfs as default filesystem. Also, it comes with a zram swap device:

$ swapon
NAME       TYPE      SIZE USED PRIO
/dev/zram0 partition   8G   0B  100

Linux (Fedora 35) on a Thinkpad P14s [T14] Gen2 AMD

These are my installation-tricks and notes for running Linux on a 2021 Thinkpad P14s Gen2 with AMD Ryzen 7 5850U. It should also be suitable for the Thinkpad T14 Gen2 AMD as they are technically the same modell.
Meanwhile there is also a good test on youtube and an entry in the arch-wiki, which also comments some points mentioned here.
