Replace obsolete WebGPU flags with state-of-the-art NVIDIA VA-API hardware decode config for Chrome 148 on Wayland/Hyprland. - Disable seccomp sandbox to fix NVIDIA GBM "Permission denied" error - Disable VulkanFromANGLE/DefaultANGLEVulkan (incompatible with Wayland) - Force ANGLE->OpenGL backend to avoid Vulkan/Wayland conflicts - Enable modern VA-API flags: VaapiOnNvidiaGPUs, AcceleratedVideoDecodeLinux* - Add gnome-libsecret password store for gnome-keyring integration - Install libva-utils and libva-nvidia-driver packages - Update driver version to 580.159.03 in hardware inventory WebGPU remains hardware accelerated via ANGLE+OpenGL. Chrome verified working with full video decode acceleration (H.264, VP9, HEVC) via NVDEC.

# Chrome 148 — NVIDIA Wayland Hardware Acceleration
|
|
|
|
Date: 2026-05-21 (updated from 2026-03-11)
|
|
|
|
## Context
|
|
|
|
Chrome on NVIDIA + Wayland has three known issues:
|
|
1. **GBM "Permission denied"**: Chrome's seccomp sandbox blocks NVIDIA's `nvidia-drm_gbm.so` on Wayland.
|
|
2. **Vulkan/Wayland incompatibility**: `--ozone-platform=wayland` is not compatible with Vulkan rendering (Chromium issue 334275637).
|
|
3. **NVIDIA VA-API allowlist**: Hardware video decode is blocked on NVIDIA without explicit flags.
|
|
|
|
The old WebGPU config (`--enable-unsafe-webgpu`, `--enable-vulkan`) is obsolete —
|
|
WebGPU works natively in Chrome 148 via ANGLE+OpenGL on Wayland without Vulkan flags.
|
|
|
|
## Required Packages
|
|
|
|
| Package | Reason |
|
|
|---------|--------|
|
|
| `libva-utils` | Verification: `vainfo` |
|
|
| `libva-nvidia-driver` | VA-API NVDEC bridge (already installed, was `nvidia-vaapi-driver`) |
|
|
|
|
Note: `libva-utils` was installed 2026-05-21. `libva-nvidia-driver` (0.0.17-1) was already present.
|
|
|
|
## Configuration: `~/.config/chrome-flags.conf`
|
|
|
|
```
|
|
--ozone-platform=wayland
|
|
--disable-seccomp-filter-sandbox
|
|
--disable-features=Vulkan,VulkanFromANGLE,DefaultANGLEVulkan
|
|
--use-angle=gl
|
|
--enable-features=VaapiOnNvidiaGPUs,VaapiIgnoreDriverChecks,AcceleratedVideoDecodeLinuxZeroCopyGL,AcceleratedVideoDecodeLinuxGL
|
|
--password-store=gnome-libsecret
|
|
```
|
|
|
|
### Flag Rationale
|
|
|
|
| Flag | Purpose |
|
|
|------|---------|
|
|
| `--ozone-platform=wayland` | Force Wayland; auto-detect unreliable on Hyprland |
|
|
| `--disable-seccomp-filter-sandbox` | Fixes GBM `Permission denied` (Chrome sandbox blocks NVIDIA GBM on Wayland) |
|
|
| `--disable-features=Vulkan,VulkanFromANGLE,DefaultANGLEVulkan` | Vulkan incompatible with Ozone Wayland; all three must be disabled |
|
|
| `--use-angle=gl` | Force ANGLE→OpenGL backend; prevents auto-selection of Vulkan |
|
|
| `--enable-features=VaapiOnNvidiaGPUs,...` | Bypass NVIDIA video decode allowlist; modern flags (replaced deprecated `VaapiVideoDecoder`) |
|
|
| `--password-store=gnome-libsecret` | gnome-keyring integration (not auto-detected outside GNOME DE) |
|
|
|
|
## Verification
|
|
|
|
```bash
|
|
vainfo # Shows VA-API NVDEC decoder capabilities
|
|
LIBVA_DRIVER_NAME=nvidia vainfo # Explicit NVIDIA VA-API check
|
|
```
|
|
|
|
Expected `chrome://gpu` results:
|
|
- Canvas: **Hardware accelerated**
|
|
- Compositing: **Hardware accelerated**
|
|
- Video Decode: **Hardware accelerated** (H.264, VP9, HEVC)
|
|
- WebGL: **Hardware accelerated**
|
|
- WebGPU: **Hardware accelerated**
|
|
- GPU: GTX 1050 Ti / NVIDIA 580.159.03
|
|
- GL implementation: `gl=egl-angle,angle=opengl`
|
|
- GPU process crash count: **0**
|
|
- Ozone platform: **wayland**
|
|
|
|
## Known Warnings
|
|
|
|
Three log lines persist despite correct config — these are upstream Chromium warnings:
|
|
|
|
```
|
|
ERROR:ui/ozone/platform/wayland/gpu/wayland_surface_factory.cc:252: '--ozone-platform=wayland' is not compatible with Vulkan
|
|
WARNING:sandbox/policy/linux/sandbox_linux.cc:404: InitializeSandbox() called with multiple threads in process gpu-process
|
|
ERROR:ui/gl/egl_util.cc:92: EGL Driver message (Error) eglCreateContext: Requested version is not supported
|
|
```
|
|
|
|
These are cosmetic. Chrome falls back to ANGLE+OpenGL before they print.
|
|
No fix exists upstream yet (Chromium issue 334275637).
|
|
|
|
## Key Learnings
|
|
|
|
1. **Deprecated flags**: `VaapiVideoDecoder`, `VaapiVideoDecodeLinuxGL` replaced by `AcceleratedVideoDecodeLinuxZeroCopyGL`, `AcceleratedVideoDecodeLinuxGL` since Chrome ≥131.
|
|
2. **Vulkan is opt-in, not opt-out**: `--disable-features=Vulkan` alone is insufficient; `VulkanFromANGLE` and `DefaultANGLEVulkan` are auto-enabled and must be listed.
|
|
3. **GBM "Permission denied" is not file perms**: It's seccomp sandbox + NVIDIA GBM. `--disable-seccomp-filter-sandbox` is the confirmed workaround.
|
|
4. **Password store**: Hyprland ≠ GNOME, so `--password-store=gnome-libsecret` explicit flag needed.
|
|
5. **`--ignore-gpu-blocklist` no longer needed**: Chrome 148 recognizes the GTX 1050 Ti + current driver without it.

## Ansible Integration
|
|
|
|
The `dev-tools` role manages this file. Update both:
|
|
- `ansible/roles/dev-tools/tasks/main.yml` (the copy task content)
|
|
- This learning doc (the rationale)
