Description

When AQ_DRM_DEVICES contains path to a symlink, Hyprland doesn't see the GPU. For example, on my system I have:

drwxr-xr-x       - root 23 Jul 11:30  /dev/dri
drwxr-xr-x       - root 23 Jul 11:30 ├──  by-name

If I set AQ_DRM_DEVICES to /dev/dri/by-name/amdgpu-card it doesn't work, but if I set it to /dev/dri/card0, it does. It used to work fine on wlroots before AQ merge.

How to reproduce

Create a symlink to /dev/dri/cardN, then set AQ_DRM_DEVICES to path to symlink, launch Hyprland.
