When I start a wlroots-based compositor (river) using
seatd, the GPU is not picked up, and rendering happens in CPU, unless I exportWLR_RENDER_DRM_DEVICE=/dev/dri/renderD128before launching the compositor.With seatd, it seems wlroots fails once, and then since seatd cannot set ACL using uaccess, it goes with cpu rendering, instead of reopening the card as non-master (I think this is what happens with elogind+polkit, where the rendering happens in gpu without the need of exporting anything).
This is on Void Linux, which uses eudev instead of udev. Not sure if this is a bug, or the result of some misconfig on my end, e.g. the kernel or mesa.
Refs: seatd ticket: https://todo.sr.ht/~kennylevinsen/seatd/24 kernel and mesa packages: https://github.com/void-linux/void-packages/pull/39796 asahi-diagnose-20241012-124206.txt
edit: I inititally had
CONFIG_DRM_VGEM=y, which led to two render nodes being present. After unsetting it, the issue still presents.
