AMD’s new Zen 4 processors started rolling out in 2022 and I’ve been watching for the mobile CPUs to reach laptops. I like where AMD is going with these chips and how they provide lots of CPU power without eating up the battery.

I recently ordered a ThinkPad Z13 Gen 2 with an AMD Ryzen 7. As you might expect, I loaded it up with Fedora Linux and set out to ensure that everything works.

This post includes all of the configurations and changes I added along the way.

Power management #

I removed the power profiles daemon that comes with Fedora by default. and replaced it with tlp. This is a great package for ThinkPad laptops as it takes care of most of the power management configuration for you with sane defaults. It also offers an easy to read configuration file where you can make adjustments.

The defaults seem to be working well so far, but my only complaint is that the power management for amdgpu seems to be really aggressive. Graphics performance on battery power is okay, but I’m told this improves in kernel 6.7. I’m on 6.6.11 in Fedora 39 right now.

I’ll wait to see if this new kernel makes any improvements.

Touchpad #

The ELAN touchpad in the Z13 is a bit different. It’s a haptic touchpad. It doesn’t push down with a click like the other thinkpads. It provides haptic feedback, much like a mobile phone does when you tap on the screen. (I usually turn this off on my phone, but it feels good on the laptop.)

The touchpad works right out of the box without any additional configuration. I made a basic Sway configuration stanza to get it configured with my preferences:

# ThinkPad Z13 Gen 2 AMD Touchpad
input "11311:40:SNSL0028:00_2C2F:0028_Touchpad" {
  drag disabled
  tap enabled
  dwt enabled
  natural_scroll disabled
}

The configuration above enables tap to click and dragging with taps. I like the old school scrolling style and I’ve disabled the natural scroll.

You can always get a list of your input devices in Sway with swaymsg:

swaymsg -t get_inputs

Display #

The display worked right out of the box but the UI elements were scaled up far too large for me. I typically value screen real estate over all other aspects, but my usual default of scaling to 1.0 made the UI far too small.

I set my output scaling to 1.2:

# Disable HiDPI
output * scale 1.2

I also enabled the RPM Fusion repos to get the freeworld AMD Mesa drivers:

sudo dnf install \
    https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm \
    https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
sudo dnf swap mesa-va-drivers mesa-va-drivers-freeworld
sudo dnf swap mesa-vdpau-drivers mesa-vdpau-drivers-freeworld

Audio #

Sound worked right out of the box, but I found that the loudness preset from easyeffects made the speakers sound a little bit better:

sudo dnf install easyeffects

Everything else #

Everything else just worked!

I’m really pleased with the performance and the battery life so far. My only complaint is that the OLED screen can be a battery hog at times.

For more details, check out the Arch Linux wiki page for the Z13. They documented lots of the function keys if you want to create keyboard shortcuts and they link to some downloadable monitor profiles.
