My Dell Pro Max 16 MC16255 with AMD Radeon 890M GPU requires some kernel parameters to work reliably on Linux. Without these, you’ll get screen artifacts and suspend issues with audio and external USB-C screens.

See also: AMD GPU artifacts, Fingerprint setup, Video codecs

Apply all parameters:

sudo grubby --update-kernel=ALL --args="amdgpu.dcdebugmask=0x410 amdgpu.dcfeaturemask=0x2 usbcore.autosuspend=-1 snd_hda_intel.power_save=0 amdgpu.vpe_enabled=0 pcie_aspm=off"
sudo reboot

What each parameter does:

Additionally, disable audio interface suspension in Wireplumber. Create ~/.config/wireplumber/wireplumber.conf.d/51-disable-suspension.conf:

monitor.alsa.rules = [
  {
    matches = [ { node.name = "~alsa_output.*" } ],
    actions = { update-props = { session.suspend-timeout-seconds = 0 } }
  }
]

Restart Wireplumber:

systemctl --user restart wireplumber

By default, PipeWire discovers and shows AirPlay audio devices from other computers on your network. This clutters your audio device list with devices you don’t need.

Disable RAOP (AirPlay audio) module in PipeWire. Create ~/.config/pipewire/pipewire.conf.d/noraop.conf:

context.properties = {
        module.raop = false
}

Restart PipeWire:

systemctl --user restart pipewire pipewire-pulse

Network audio devices from other computers will no longer appear in your audio settings.

Apparently, it is quite common for AMD GPUs to show screen artifacts on Linux. Most of the times it is related to power management settings. These settings can be adjusted via amdgpu kernel module options. The parameters are different for different GPUs. In my case, I have a Dell laptop with AMD Radeon 890M GPU.

To fix the screen artifacts, run the following commands:

sudo grubby --update-kernel=ALL --args="amdgpu.dcdebugmask=0x410"

Reboot your system.

Dell laptops come with a different fingerprint readers. Some of them work out of the box in Fedora and that was my expierince with Precision series. However, my new Dell Pro Max 16 MC16255 came with a different unsupported fingerprint.

Find your fingerprint reader

sudo lsusb

You should see something like this:

Bus 003 Device 002: ID 0a5c:5865 Broadcom Corp. 58200

Where 5865 is the model of the fingerprint reader. There are some copr repositories around that provide support for some of the models, but not for 5865.

There is a good article on Reddit that explains how to get it working.

The solution is to manually install the released driver from Dell for Ubuntu.

Go to Dell support site and download the latest libfprint-2-tod1-broadcom-cv3plus orig package.

Extract it and move:

../usr/lib/x86_64-linux-gnu/libfprint-2/tod-1/libfprint-2-tod-1-broadcom-cv3plus.so

to

../usr/lib64/libfprint-2/tod-1/libfprint-2-tod-1-broadcom-cv3plus.so

One-liner:

mkdir -p ../usr/lib64/libfprint-2/tod-1/ && mv ../usr/lib/x86_64-linux-gnu/libfprint-2/tod-1/libfprint-2-tod-1-broadcom-cv3plus.so $_

Run the included install script:

sudo ./install.sh

Replace libfprint package:

sudo dnf copr enable quantt/libfprint-tod -y
sudo dnf swap libfprint libfprint-tod -y

Programmatically add your fingerprint:

sudo setenforce 0
sudo systemctl restart fprintd
fprintd-enroll
sudo ausearch -m avc,user_avc,selinux_err -ts today | sudo audit2allow -M fprintd_SELinux
sudo semodule -i fprintd_SELinux.pp
sudo setenforce 1

To enable fingerptint authentication:

sudo authselect enable-feature with-fingerprint
sudo authselect apply-changes

Fingerprint configuration should be also available in GNOME Settings under “Users”.

Install all good (the ones that work) video codecs for AMD GPU:

# Enable RPM Fusion repositories
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

# Install hardware acceleration libraries for AMD
sudo dnf swap mesa-va-drivers mesa-va-drivers-freeworld
sudo dnf swap mesa-vdpau-drivers mesa-vdpau-drivers-freeworld

# Switch to full ffmpeg package
sudo dnf swap ffmpeg-free ffmpeg --allowerasing

# Install additional codecs
sudo dnf group update multimedia --setopt="install_weak_deps=False" --exclude=PackageKit-gstreamer-plugin
sudo dnf group update sound-and-video
sudo dnf install gstreamer1-plugin-openh264 mozilla-openh264
sudo dnf config-manager setopt fedora-cisco-openh264.enabled=1

Modern font configuration for Linux:

gsettings set org.gnome.desktop.interface font-name "Adwaita Sans 11"
gsettings set org.gnome.desktop.interface document-font-name "Adwaita Sans 11"
gsettings set org.gnome.desktop.interface monospace-font-name "Noto Sans Mono 11"

Adwaita Sans is the new default font for GNOME desktop environment. It looks great and modern. Noto Sans Mono is a great monospaced font for programming.

To install Noto fonts on Fedora, run:

sudo dnf install google-noto-sans-fonts
