Fixing OpenCL/GPU Acceleration for AMD Radeon on Ubuntu

Problem

Video editors (Kdenlive, DaVinci Resolve, etc.) had broken GPU acceleration on Ubuntu 25.04 with AMD Radeon RX 7700 XT.

Running clinfo showed:

Number of platforms: 0

Despite having ROCm 6.3 installed, OpenCL wasn't working.

Diagnosis

ROCm was installed but the OpenCL ICD (Installable Client Driver) was missing:

ls /etc/OpenCL/vendors/
# Empty directory

Solution

Install the ROCm OpenCL ICD package:

sudo apt install rocm-opencl-icd

This creates /etc/OpenCL/vendors/amdocl64.icd which registers the AMD OpenCL implementation with the system.

Verification

After installation, clinfo should show your GPU:

clinfo | grep -E "Platform Name|Device Name|Device Board"

Expected output:

Platform Name                                   AMD Accelerated Parallel Processing
Device Name                                     gfx1101
Device Board Name (AMD)                         AMD Radeon RX 7700 XT

Result

• DaVinci Resolve now detects GPU for color grading acceleration
• Kdenlive GPU rendering works
• Any OpenCL-based video processing is now hardware accelerated

Environment

• Ubuntu 25.04
• AMD Radeon RX 7700 XT (gfx1101 / Navi 32)
• ROCm 6.3.0
• KDE Plasma (Wayland)
