fedora-niri-dms

An installer script that turns a minimal, terminal-only Fedora install into a complete niri + DankMaterialShell desktop, with the DMS login screen.

Quick start

1. Install Fedora from the Everything netinstall ISO and choose Fedora Custom Operating System under Software Selection. Create a user with administrative privileges.
2. Boot to the text login, sign in, and run:

curl -fsSL https://gitea.schantli.ca/jschantli/fedora-niri-dms/raw/branch/main/fedora-niri-dms-setup.sh -o setup.sh
bash setup.sh

Run it as your normal user, not root. It uses sudo when it needs to.

3. Answer the optional questions at the start. The rest runs unattended.
4. Reboot, pick the niri session at the login screen, and sign in.

Press Super+Shift+/ after logging in to see every keybind.

niri config	Waybar disabled (DMS is the bar), Super+T opens Ptyxis, Super+D opens the DMS launcher, Super+Alt+L locks with DMS

Optional (asked at the start)

• Steam and gamescope
• NetworkManager OpenVPN support (for PIA or other .ovpn configs)
• Fingerprint reader setup (Framework laptops)
• EasyEffects (for Framework's speaker profile)

Requirements

• Fedora 43 or newer, installed as Fedora Custom Operating System
• An internet connection
• A GPU with working acceleration

Testing in a VM

niri needs 3D acceleration, or you'll get a black screen after reboot. Turn it on before rebooting:

• Proxmox: Display → VirGL GPU (host needs apt install libgl1 libegl1)
• virt-manager / GNOME Boxes: Virtio video with 3D acceleration, Spice with OpenGL
• VirtualBox: VMSVGA with Enable 3D Acceleration
• VMware: Accelerate 3D graphics

Troubleshooting

Problem	Fix
Black screen after reboot	Ctrl+Alt+F2, log in, then run niri-session or dms greeter status
DMS bar doesn't appear	Run dms run to see the error; check systemctl --user status dms
No sound	systemctl --user status pipewire wireplumber, then wpctl status
Screen sharing shows nothing	Check xdg-desktop-portal-gnome is installed, then log out and back in
Keyring asks for a password every login	sudo authselect enable-feature with-pam-gnome-keyring and reboot

Notes

• The script is safe to re-run; each step checks before changing anything.
• Steam menu fix: xwayland-satellite 0.8.2 and older make X11 popup menus (like Steam's) flicker and vanish. If Fedora's package is affected, the script builds the fixed upstream commit (add2795) into /usr/local/bin. A boot-time check (xwls-git-check.service) deletes that build, and then itself, once Fedora ships a newer version.
• Your original niri config is saved as ~/.config/niri/config.kdl.orig before it's edited.
• No HDR yet: niri doesn't support it. HDR gaming needs a separate gamescope session.
• DMS comes from the stable avengemedia/dms COPR, not the faster-moving dms-git.
