dxdiag tells me I have Intel HD Graphics 520 and AMD Radeon R7 M340

wsl.exe --version returns

WSL version: 1.0.0.0
Kernel version: 5.15.74.2
WSLg version: 1.0.47
MSRDC version: 1.2.3575
Direct3D version: 1.606.4
DXCore version: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp
Windows version: 10.0.22000.1281

and wsl --status says

Default Distribution: Ubuntu-22.04
Default Version: 2

From inside wsl, uname -a gives

5.19.0-microsoft-standard #2 SMP PREEMPT_DYNAMIC Wed Aug 3 01:11:12 +04 2022 x86_64 x86_64 x86_64 GNU/Linux

and glxinfo -B returns

There is no /drv/dxg on my system. The content of /usr/lib/x86_64-linux-gnu/dri is

crocus_dri.so
iris_dri.so
nouveau_dri.so
r600_dri.so
swrast_dri.so
vmwgfx_dri.so
d3d12_dri.so
kms_swrast_dri.so
r300_dri.so
radeonsi_dri.so
virtio_gpu_dri.so
zink_dri.so

Is there a way to make gpu acceleration work?

With the recent release of the WSL application package (available from the Microsoft Store or a direct download AppX/MSIX bundle), which you are clearly running, GPU acceleration of WSLg for running Linux applications should be available to many systems. I don't have an AMD system, but my understanding from this devblog post is that it should work on your system.

There are (at least) three things required for GPU accelerated rendering under WSL:

  • A recent release of WSL (which you clearly have):
  • A WSL2 kernel with dxgkrnl support
  • Windows drivers for your GPU with support for WDDM v2.9 or later

Windows/WSL prerequisite

While you seem to already have this in place, I'll include it for other readers. You'll need either:

  • Windows 11: All WSL versions
  • Windows 10: A build number ending in 2311 or higher. You can check this number (the UBR - update-build-number) using (Get-ComputerInfo).WindowsUBR in PowerShell. See the "WSLg on Windows 10: Prerequisites" part of this answer for more information.

A WSL2 kernel with dxgkrnl support

From your output above, I'm hoping your problem is pretty straightforward -- I notice that the kernel version reported by uname -a is different than that reported by wsl --version. I'm assuming that you have a custom kernel compiled and defined in your %userprofile%\.wslconfig? If so, try removing that line, restarting WSL (wsl --shutdown) and check again.

Windows drivers for your GPU with support for WDDM v2.9 or later

Finally, make sure that your Windows drivers for your Radeon include support for WDDM 2.9 or later. This can be confirmed through the dxdiag command in Windows under the Display tab.

If you are below 2.9, make sure you are running the latest Catalyst drivers. I can't tell you for sure if your card will support 2.9 with the latest drivers, but I believe it should.
