Oftentimes, describing the problem helps me to think of things to google for. There are a lot of posts about high CPU usage in xfce over the years, for all sorts of reasons (e.g. binary display drivers), but I found https://forum.artixlinux.org/index.php/topic,980.0.html and indeed the xfce calculator plugin WAS the problem. With that removed, Xorg is back to around 2% CPU usage. ĸen -- When someone told me I lived in a fantasy land I nearly fell off my unicorn. -- http://lists.linuxfromscratch.org/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
