# Stable, colon-free symlinks for the DRM devices.
|
|
#
|
|
# Why this exists: Hyprland's AQ_DRM_DEVICES selects which GPU renders, but
|
|
# - /dev/dri/cardN numbering is assigned at boot and is not stable, and
|
|
# - /dev/dri/by-path/ names contain colons, which AQ_DRM_DEVICES itself uses
|
|
# as its separator, so they cannot be used.
|
|
#
|
|
# These rules are keyed to specific PCI addresses and simply do not match on
|
|
# other machines; hypr/env.lua checks that the symlink exists before setting
|
|
# AQ_DRM_DEVICES, so a non-match is harmless.
|
|
#
|
|
# Apply without rebooting: sudo udevadm control --reload && sudo udevadm trigger
