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
Verify your GPU:
/sbin/lspci | grep -e VGA
Make sure you:
Make sure you system is up to date (reboot if something was installed):
sudo dnf update -y
Install nvidia driver:
sudo dnf install akmod-nvidia
sudo dnf install xorg-x11-drv-nvidia-cuda
Wait until kernel module is compiled.
Enable video acceleration and some extras:
sudo dnf install vdpauinfo libva-vdpau-driver libva-utils xorg-x11-drv-nvidia-cuda-libs xorg-x11-drv-nvidia-cuda
Reboot system.
Verify that nouveau driver is disabled:
lsmod |grep nouveau
Edit this /etc/selinux/config file and follow instructions
By default fedora uses Wayland. Make sure the following section exists in /etc/gdm/custom.conf:
[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false
DefaultSession=gnome-xorg.desktop
Default Printer application in GNOME (fedora 33) is not able to successfully configure wireless printer, it needs to be done manually:
sudo dnf install hplip hplip-gui
sudo hp-setup
Select Network/Ethernet/Wireless network and your printer will appear in the list. Follow the instructions and add the printer.
If you are experiencing high CPU usage when watching videos on youtube, verify that the following packages are installed (requires RPMFusion repository):
# RPMFuison 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
# Codecs
sudo dnf install gstreamer1-plugins-{bad-\*,good-\*,base} gstreamer1-plugin-openh264 gstreamer1-libav --exclude=gstreamer1-plugins-bad-free-devel
sudo dnf install lame\* --exclude=lame-devel
sudo dnf group upgrade --with-optional Multimedia
CPU usage for i3-8100T is down from 80% to 50% with this video sample
