It seems the
CONFIG_DRMandCONFIG_DRM_VGEMoptions are removed in the latest kernel config. Mitchell Levy (@chessturo) . Could you please help take a look? Thanks.dootn commentedon Aug 28, 2026
I can confirm this. The issue appears to be caused by [commit 7e83488](microsoft/WSL2-Linux-Kernel@7e83488), which removes
CONFIG_DRMandCONFIG_DRM_VGEM=mfrom the x86 WSL kernel config. This explains thevgemmodule not being found.chessturo commentedon Aug 28, 2026
Hi --- what's loading vgem? To be clear, you're not noticing any changes to behavior beyond the line in dmesg?
dootn commentedon Aug 31, 2026
Just to clarify why
vgemis needed here: it is part of the DRM side of the WSLg vGPU acceleration path.The WSLg documentation for vGPU-accelerated video requires
/dev/dri/card0and/dev/dri/renderD128in addition to/dev/dxg:There are also a couple of related WSL issues showing the relationship between
vgemand the/dev/dridevices: #11837 and #12633.marcorotondi commentedon Aug 31, 2026

By default the Whitewater Foundry's Fedora Remix for WSL loads this on every login through
/etc/profile.d/00-remix.sh->/usr/local/bin/fedoraremix-load-vgem-modulein order to accelerate WSLg as Ben mentioned.crramirez commentedon Oct 4, 2026
Pengwin maintainer here. The vgem module is needed for VA Video Acceleration. I added modified Pengwin's startup script to mute the error, but without this module, libva stop working.
