# Sourced by uwsm before Hyprland starts.
# Keep Hyprland on the AMD iGPU (Radeon 8060S, PCI c4:00.0). The Thunderbolt
# eGPU (RTX 5060 Ti) drives no displays and is for compute only; without this,
# aquamarine opens it as a second KMS device. cardN numbering shifts with eGPU
# hotplug timing, so resolve the stable by-path link. Left unset if missing so
# Hyprland still falls back to auto-detection.

# EGL through Mesa only, for Hyprland and every app in the session. glvnd
# otherwise tries NVIDIA's vendor first (10_nvidia.json sorts before
# 50_mesa.json), so the compositor and GL apps open /dev/nvidiactl even
# though they render on the iGPU; when the eGPU drops off the bus, they
# would be holding it. CUDA does not go through EGL and is unaffected.
