DaVinci Resolve - Omarchy

Video Guide

Install DaVinci Resolve on Omarchy (Arch Linux + Hyprland) with NVIDIA GPU support.

Handles all the compatibility quirks of running Resolve on Arch Linux — library conflicts, XWayland setup, RPATH patching, and legacy library shims — so you don't have to.

Requirements

• OS: Omarchy (Arch Linux)
• GPU: NVIDIA with proprietary drivers installed and working
• Disk space: ~10GB free in ~/Downloads for extraction (temporary)
• DaVinci Resolve ZIP: Downloaded from Blackmagic's website

Quick Start

1. Download DaVinci Resolve from blackmagicdesign.com

   • Choose "DaVinci Resolve" (free) or "DaVinci Resolve Studio" (paid)
   • Select Linux and download the ZIP file
   • Save it to ~/Downloads/

2. Run the installer:

git clone https://git.no-signal.uk/nosignal/DaVinci-Resolve-Omarchy.git
cd DaVinci-Resolve-Omarchy
chmod +x Omarchy_resolve_v2.sh
./Omarchy_resolve_v2.sh

3. Launch Resolve from your app menu or run resolve-nvidia-open

What It Does

1. Installs Dependencies

Build/extraction tools:

Package	Purpose
unzip	Extracts the Resolve ZIP archive
patchelf	Modifies library search paths (RPATH) in binaries
libarchive	Archive handling library
desktop-file-utils	App menu integration
file	Identifies ELF binaries for RPATH patching

Runtime dependencies:

Package	Purpose
libxcrypt-compat	Provides legacy libcrypt.so.1 (Arch dropped it)
ffmpeg4.4	Older FFmpeg version that Resolve links against
glu	OpenGL Utility Library for 3D rendering
gtk2	GTK2 toolkit (some Resolve UI components use it)
fuse2	AppImage compatibility layer

2. Extracts Resolve

The download is a ZIP containing a .run file (self-extracting AppImage). The script unpacks it in stages:

ZIP → .run file → squashfs-root (actual application files)

Temporary files are cleaned up automatically when the script finishes.

3. Handles Library Conflicts (ABI-Safe)

This is the tricky part. Resolve bundles its own libraries, but some conflict with Arch's newer versions:

Library	Action	Why
libglib-2.0.so	Replace with system	Stable C ABI, safe to swap
libgio-2.0.so	Replace with system	Stable C ABI, safe to swap
libgmodule-2.0.so	Replace with system	Stable C ABI, safe to swap
libc++.so	Keep bundled	C++ ABI mismatch causes crashes
libc++abi.so	Keep bundled	C++ ABI mismatch causes crashes

4. Patches RPATH

Every ELF binary in Resolve gets its RPATH patched to point to /opt/resolve/libs/ and subdirectories. Without this, binaries would look for libraries in the original AppImage paths that no longer exist.

5. Creates XWayland Wrapper

Resolve doesn't support native Wayland. The wrapper script (resolve-nvidia-open) forces XWayland mode by setting QT_QPA_PLATFORM=xcb, and also clears stale Qt lockfiles that can prevent Resolve from starting after a crash.

6. Desktop Integration

• Installs .desktop files for the app menu
• Installs icons at proper hicolor sizes
• Installs udev rules for Blackmagic hardware (capture cards, control panels)
• Points all launchers at the XWayland wrapper

7. Audio Backend Fix (DeckLink → ALSA + snd-aloop)

Two issues are fixed automatically:

Default audio backend. Resolve's shipped default-config.dat sets Local.Audio.Type = DeckLink, which causes Resolve to abort on first launch on systems without a Blackmagic DeckLink capture/playback card. The script patches both the system template and any existing user config to use ALSA (backing up the user config to config.dat.bak.<timestamp>).

Render-blocker hang. Resolve's audio engine opens raw ALSA hardware (hw:N) and enumerates every card under /dev/snd/control*. When all real ALSA cards are owned/contested by PipeWire's session manager, the enumeration retries forever — the render queue never spawns the encoder, the job sits at "in progress" with growing ETA, no output file appears, and nothing useful lands in ResolveDebug.txt. strace shows tens of thousands of SNDRV_CTL_IOCTL_PCM_INFO ENXIO ioctls per failed render.

The fix is to load the kernel's snd-aloop module. PipeWire ignores it (no ACP profile, not auto-acquired), so Resolve can fully own it and the render proceeds normally. The script:

• Runs modprobe snd-aloop for the current session
• Writes /etc/modules-load.d/snd-aloop.conf so it autoloads at boot
• Writes a PipeWire loopback bridge at ~/.config/pipewire/pipewire.conf.d/50-resolve-aloop-bridge.conf so monitor audio routes from the loopback's capture side to the system default sink (without it, Resolve renders fine but you hear nothing during playback; headphone/HDMI sink switching keeps working through the bridge)
• Restarts user PipeWire services so the bridge loads immediately

Set RESOLVE_NO_ALOOP=1 to skip this entirely (useful if you have a dedicated audio interface Resolve already uses cleanly).

Configuration

Full System Upgrade

By default, the script syncs the package database without upgrading. To include a full system upgrade:

RESOLVE_FULL_UPGRADE=1 ./Omarchy_resolve_v2.sh

Skip the snd-aloop Audio Fix

If you have a dedicated audio interface (e.g. Focusrite Scarlett, MOTU, etc.) that Resolve already uses cleanly, you don't need the virtual loopback card:

RESOLVE_NO_ALOOP=1 ./Omarchy_resolve_v2.sh

This skips the modprobe snd-aloop, the /etc/modules-load.d/ entry, and the PipeWire loopback bridge. The DeckLink → ALSA config patch still runs.

Hybrid GPU Laptops (Optimus)

If you have an Intel iGPU + NVIDIA dGPU, edit the wrapper to force Resolve onto the NVIDIA GPU:

sudo nano /usr/local/bin/resolve-nvidia-open

Uncomment these lines:

export __NV_PRIME_RENDER_OFFLOAD=1
export __GLX_VENDOR_LIBRARY_NAME=nvidia

Troubleshooting

Resolve won't start / crashes immediately

• Check logs: ~/.local/share/DaVinciResolve/logs/ResolveDebug.txt
• Verify NVIDIA driver is working: nvidia-smi
• Try launching from terminal to see errors: resolve-nvidia-open

"Cannot open display" error

• Make sure XWayland is enabled in Hyprland (it is by default on Omarchy)
• Check the wrapper is using xcb: grep QT_QPA_PLATFORM /usr/local/bin/resolve-nvidia-open

Resolve says "single instance already running"

Stale lockfiles from a previous crash. The wrapper clears these automatically, but if it persists:

rm -f /tmp/qtsingleapp-DaVinci*

Render queue says "in progress" forever, no output file

This is the audio render-blocker hang — Resolve's audio engine is stuck enumerating ALSA cards. Confirm snd-aloop is loaded:

lsmod | grep snd_aloop

If absent, load it and retry:

sudo modprobe snd-aloop

If you ran the installer with RESOLVE_NO_ALOOP=1 and want to opt back in, re-run the installer without that variable, or do it manually:

sudo modprobe snd-aloop
echo 'snd-aloop' | sudo tee /etc/modules-load.d/snd-aloop.conf

If lsmod shows snd_aloop is loaded but renders still hang, check the clip codec with ffprobe — ProRes RAW will hang silently on Linux without Apple's ProRes RAW SDK plugins, which is a separate issue from this audio fix.

No audio during playback / monitor sink switches don't work

The PipeWire loopback bridge at ~/.config/pipewire/pipewire.conf.d/50-resolve-aloop-bridge.conf routes the snd-aloop capture side to your default sink. If headphone/HDMI switching stops working for Resolve playback, restart user PipeWire services:

systemctl --user restart pipewire pipewire-pulse wireplumber

To remove the bridge entirely:

rm ~/.config/pipewire/pipewire.conf.d/50-resolve-aloop-bridge.conf
systemctl --user restart pipewire pipewire-pulse wireplumber

Missing library errors

Re-run the installer — it will re-patch RPATH and re-check dependencies:

./Omarchy_resolve_v2.sh

GPU not detected / OpenCL errors

• Ensure NVIDIA drivers are installed: pacman -Qi nvidia-utils
• Check GPU is visible: nvidia-smi
• Verify OpenCL: pacman -S --needed opencl-nvidia

Updating Resolve

1. Download the new version ZIP from Blackmagic's website to ~/Downloads/
2. Run the installer again — it automatically picks the newest ZIP:

./Omarchy_resolve_v2.sh

The previous installation at /opt/resolve will be replaced.
