DESCRIPTION="Program for querying and changing monitor settings"
HOMEPAGE="http://www.ddcutil.com/"
SRC_URI="https://github.com/rockowitz/ddcutil/archive/v${PV}.tar.gz -> ${P}.tar.gz"
# Binary drivers need special instructions compared to the open source counterparts.
# If a user switches drivers, they will need to set different use flags for
# Xorg or Wayland or Mesa, so this will trigger the rebuild against
# the different drivers.
# Remove ATI/AMD driver since it's masked for removal.
# Will most likely need to set this for AMDGPU when in portage.
