Unable to enable GPU Acceleration on uConsole (CM5 + latest Rex's Kali ) - Stuck on llvmpipe

uConsole

Hi everyone,

I’m running Kali Linux with the XFCE desktop environment on my ClockworkPi uConsole, but I’m unable to get GPU hardware acceleration working. The system is falling back to CPU software rendering.

When I run glxinfo | grep "OpenGL renderer", it shows:

OpenGL renderer string: llvmpipe (LLVM 16.0.6, 128 bits)

Here is what I have tried so far:

  1. Checked /boot/firmware/config.txt and ensured the VC4 V3D overlay is present:

    [cm5]

    dtoverlay=vc4-kms-v3d-pi5
    gpu_mem=256

  2. Installed Mesa DRI/GL packages (libgl1-mesa-dri, mesa-utils, xserver-xorg-video-modesetting).

Despite these steps, glxinfo still reports llvmpipe, and overall UI performance (especially SDR++ waterfall display due to high CPU load.

Has anyone successfully enabled VC4/V3D DRM hardware acceleration on Kali Linux for the uConsole? Am I missing specific firmware packages, kernel modules, or DRM/KMS node configurations for this screen setup?

Any pointers or working config files would be greatly appreciated!

Thanks in advance!
