# DaVinci Resolve - Omarchy

## Video Guide

Install [DaVinci Resolve](https://www.blackmagicdesign.com/products/davinciresolve) on [Omarchy](https://omarchy.com) (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](https://omarchy.com) (Arch Linux)
- **GPU**: NVIDIA with proprietary drivers installed and working
- **Audio stack**: PipeWire + Wireplumber **0.5 or newer** (Omarchy default)
  — the audio fix uses the SPA-JSON rule format introduced in 0.5
- **Kernel**: Stock Arch kernel (or any with `snd-aloop` available — verify
  with `modinfo snd-aloop`)
- **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](https://www.blackmagicdesign.com/products/davinciresolve)
   - Choose "DaVinci Resolve" (free) or "DaVinci Resolve Studio" (paid)
   - Select **Linux** and download the ZIP file
   - Save it to `~/Downloads/`

2. **Run the installer**:
```bash
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 |
| `fuse2` | AppImage compatibility layer |

Packages are installed individually so one unavailable package can't abort
the rest. (`gtk2` used to be on this list — Arch moved it to the AUR and
Resolve 19+ no longer needs it, so it was dropped.)

### 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. It additionally unsets Omarchy's global `QT_STYLE_OVERRIDE=kvantum` / `QT_QPA_PLATFORMTHEME=gtk3` — Resolve's bundled Qt has neither plugin, so this just silences Qt style warnings.

### 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` + Wireplumber rule)

Three pieces are needed for Resolve audio to actually work — all three are
applied automatically. Skipping any one of them leaves a different failure
mode visible (Resolve aborts on first launch / renders hang forever / monitor
audio loops onto itself).

**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 current
  system default sink (without it, Resolve renders fine but you hear
  nothing during playback; headphone/HDMI sink switching keeps working
  through the bridge)
- Writes a Wireplumber rule at
  `~/.config/wireplumber/wireplumber.conf.d/51-resolve-aloop-no-default.conf`
  that excludes the aloop card from default-sink selection — without this,
  Wireplumber would promote aloop to default whenever Resolve plays audio
  (because aloop is RUNNING), and the bridge would loop audio back into
  aloop instead of your real hardware
- Restarts user Wireplumber + PipeWire services so the configs load
  immediately

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

### 8. Full Opacity for Grading (Omarchy 4)

Omarchy 4 applies a default translucency (0.985 focused / 0.96 unfocused) to
every window via its Hyprland Lua config, and its built-in Resolve rule
doesn't opt out — a translucent window is wrong for colour-critical work.
When an Omarchy 4 Lua config is detected, the installer appends a
`resolve-full-opacity` rule to `~/.config/hypr/hyprland.lua` (loaded after
Omarchy's defaults, so it wins) forcing Resolve back to `opacity 1 1`.
Idempotent; skipped entirely on pre-4 installs, which never applied global
translucency. To remove it, delete the `resolve-full-opacity` block from
`~/.config/hypr/hyprland.lua`.

This one has since landed upstream ([basecamp/omarchy#6382](https://github.com/basecamp/omarchy/pull/6382)),
so on current Omarchy the rule is a harmless duplicate of Omarchy's own; it
still matters on Omarchy 4 builds predating that PR.

### 9. Omarchy Bar Overlap Fix

On Omarchy 4.x, Resolve launches with its own menu bar (File / Edit / Trim /
Timeline / …) hidden underneath the Omarchy status bar, so those menus can't be
clicked.

The Omarchy bar is a layer-shell surface on Hyprland's `top` layer that reserves
26px at the top of the screen. That reserved space only constrains *tiled*
windows — and Omarchy deliberately floats every Resolve window, because
Resolve's many child windows tile badly. Floating windows are positioned by the
client, and Resolve's XWayland main window places itself at 0,0 at the full
monitor size, ignoring the reserved zone. The bar then draws on top of it.

Hyprland renders a fullscreen window *above* `top`-layer surfaces, so the script
installs a Hyprland rule that opens Resolve's main window fullscreen — putting
Resolve over the bar instead of under it. The bar isn't hidden or killed, and
behaves normally again as soon as you leave fullscreen or focus another window.

The rule is scoped by window title, because every Resolve window shares the same
class and only the main one may be fullscreened:

| window          | title                              | fullscreened? |
|-----------------|------------------------------------|---------------|
| splash screen   | `resolve`                          | no            |
| project chooser | `Project Manager`                  | no            |
| modal dialogs   | e.g. `Preferences`                 | no            |
| main window     | `DaVinci Resolve - <project name>` | yes           |

Two files are written (`~/.config/hypr/davinci-resolve.lua` and one `require`
line appended to `~/.config/hypr/hyprland.lua`), then Hyprland is reloaded.
Re-running the installer won't duplicate the `require`, and `hyprland.lua` is
backed up before it's touched.

### 10. Dialog Pointer Trap Fix

Opening Resolve's **Preferences** or **Project Manager** could trap the pointer:
the dialog couldn't be dismissed, nothing else could be clicked, and quitting
Resolve was the only way out.

Omarchy sets `stay_focused = true` on every Resolve window. That rule exists for
a good reason — Resolve isn't Wayland-native, so its transient popups (Change
Clip Duration, Normalize Audio Levels…) close as soon as the pointer leaves them
unless focus is pinned ([Hyprland #12235](https://github.com/hyprwm/Hyprland/discussions/12235)).
Deleting it outright would bring that problem back.

The trouble is it's applied to *all* Resolve windows. When two are visible at
once, both demand focus and neither yields, so Hyprland flips between them
forever. Captured live:

```
ACTIVE='Create New Project'  windows=['Project Manager', 'Create New Project']
ACTIVE='Project Manager'     windows=['Project Manager', 'Create New Project']
ACTIVE='Create New Project'  windows=['Project Manager', 'Create New Project']
```

The script narrows the rule instead of removing it: the pin stays on the
transient popups, and comes off the two windows those popups open *over* — the
main window and the Project Manager. At most one pinned window is ever visible,
so nothing can fight, and every window that relied on the pin still has it.

Set `RESOLVE_NO_HYPR_RULES=1` to skip both Hyprland rules entirely.

## Configuration

### Full System Upgrade

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

```bash
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:

```bash
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.

### Skip the Hyprland Window Rules

If you would rather the installer left your Hyprland config alone entirely:

```bash
RESOLVE_NO_HYPR_RULES=1 ./Omarchy_resolve_v2.sh
```

Neither `~/.config/hypr/davinci-resolve.lua` nor the `require` line is written.
The separate full-opacity rule (§8) is not covered by this switch — remove its
`resolve-full-opacity` block from `hyprland.lua` if you don't want it either.
The installer also skips the rules
automatically (with a warning showing the equivalent `windowrulev2` line) if
`~/.config/hypr/hyprland.lua` doesn't exist — i.e. on non-Omarchy-4.x setups
that still use `hyprland.conf`.

### Hybrid GPU Laptops (Optimus)

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

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

Uncomment these lines:
```bash
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:

```bash
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:

```bash
lsmod | grep snd_aloop
```

If absent, load it and retry:

```bash
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:

```bash
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 / sink keeps flipping to "Loopback"

If your system default sink keeps switching to "Loopback Analog Stereo"
the moment Resolve starts playing, the wireplumber exclusion rule isn't
in effect. Confirm the rule file exists:

```bash
cat ~/.config/wireplumber/wireplumber.conf.d/51-resolve-aloop-no-default.conf
```

If absent, re-run the installer or pin your real sink manually:

```bash
pactl set-default-sink <your-real-sink-name>      # e.g. alsa_output.pci-0000_01_00.1.hdmi-stereo
```

If headphone/HDMI switching stops working for Resolve playback, restart
the user audio stack (wireplumber first):

```bash
systemctl --user restart wireplumber pipewire pipewire-pulse
```

To remove the bridge + rule entirely:

```bash
rm ~/.config/pipewire/pipewire.conf.d/50-resolve-aloop-bridge.conf
rm ~/.config/wireplumber/wireplumber.conf.d/51-resolve-aloop-no-default.conf
systemctl --user restart wireplumber pipewire pipewire-pulse
```

### Missing library errors

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

```bash
./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:

```bash
./Omarchy_resolve_v2.sh
```

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