I am not sure the graphics card is actived,I can’t use kwin effect, my second mointor signal output from laptop shows black screen.(it connect through d-sub port),
my laptop is lenovo G500,with intel hd4000 and amd radeon graphics,Can I use only intel or amd ? because I heard I can’t use hybrid graphics card in openSUSE.thanks
