What GPU and what Windows driver version are you running?

What's the output for glxinfo -B ?

Does GALLIUM_DRIVER=llvmpipe glxgears work?

[intellild]

llvmpipe works fine

here is the output of glxinfo -B

Where can I get the latest driver ? I noticed that the Intel driver in the readme link is more than one year old

[onomatopellan]

intel so far has just released these https://downloadcenter.intel.com/download/29526
They need to release Windows 11 preview drivers yet.

So far Nvidia is the only manufacturer that truly cared about WSL2 support, often releasing drivers especially for CUDA support.

[intellild]

updated to latest Intel driver, the problem still exists

[spronovo]

Hi @intellild, could you run dxdiag.exe (windows+r -> dxdiag.exe) on Windows, click on Save All Information... and attach the file here so we can see exactly which driver are you using.

I have the same issue, unfortunately. Using Intel UHD Graphics 630. Can I run wsl on the dedicated NVIDIA GPU (I have a laptop with hybrid graphics)? Also, I am on Windows 11 as well, is that the problem? When will this finally be available with a proper retail Windows version? I have been waiting for this for a long time, similar to how disk mounting is available in WSL2 since at least one year ago but it till hasn't shipped with a stable Windows version yet...

Same issue here with the latest Intel driver. And this also happens to Wayland applications.

I have the same issue with an Intel i5-8250U (Intel UHD Graphics 620). I believe the bug is most likely due to the driver released by Intel, but this information may be of use to the WSLg team. My understanding is that a WDDM 3.0 driver is required. I updated to the latest Intel DCH driver which is a WWDM 3.0 driver, however now I also see a blank, blank viewport for OpenGL applications.

Windows build: Windows 11, 10.0.22000.348
Linux distribution: Ubuntu 20.04, 2021-12-07
WSLg version: 1.0.26
Intel DCH driver: 30.0.101.1069

glxinfo -B

inxi -F

I have also tried the beta Intel DCH driver, but this also did not appear to fix the issue.

Intel beta DCH driver: 30.0.101.1121

I sent a bug report to Intel, however someone at Microsoft may have a more direct contact.

EDIT: Happy to provide any more information required.

I did recieve an update from Intel, with fairly unsatisfactory answer:

This has been checked by our Engineers and their findings are as follows: There are a lot of dependencies, not just the graphics that can cause the blank screen that the customer has encountered. Since the issue is with the WSLg, it would be best if the customer contacts Microsoft about the issue.

We understand that this is not the resolution that you are looking for however, it would be best to contact Microsoft Support.

Not sure on the best way to proceed. Would you have any suggestions or ideas @spronovo to help find the root cause.

Having the same issue, my wsl is up-to-date as of this morning, happy to provide any other info if it will help.

[Zopolis4]

setting LIBGL_ALWAYS_SOFTWARE to 1 fixes it, although then I'm not running with hw accel

On some laptops, e.g. Lenovo T15g, when an external monitor is connected the NVIDIA adapter is activated.
You have to assign nvidia to the environment variable MESA_D3D12_DEFAULT_ADAPTER_NAME to force OpenGL to use the nvidia graphics card. See GPU selection in WSLg.

export MESA_D3D12_DEFAULT_ADAPTER_NAME=nvidia
