Description:
kde powerdevil has ddci support added, but it is not enabled in archlinux, so unable to control hdmi/displayport display brightness more info: https://www.reddit.com/r/archlinux/comments/epbuuf/kde_my_journey_to_get_a_brighness_slider_for_my/ Additional info: package version: powerdevil-5.19.4 Steps to reproduce: install powerdevil from extra repo |
This task depends upon
add_feature_info("DDCUtil" HAVE_DDCUTIL "DDCUtil library support is disabled by default as recommended by authors, add -DHAVE_DDCUTIL=On to enable")
Plus, ddcutil support is poorly maintained, to the point that it constantly breaks with new versions of ddcutil, with upstream failing to catch up with the changes (see the two year old https://bugs.kde.org/show_bug.cgi?id=398473). In fact it doesn't build with the latest version of ddcutil currently in our repos. We can't enable this until it gets proper support upstream.
