Just for the record My Dell Latitude E7440 (Intel graphics card only) experiences the same problem with Xubuntu 16.04 Xenial Xerus (issue was not present in Xubuntu 12.04, and I didn't tried intermediate versions) I tried several workarounds but none seems to work this far.
I updated to Kernell 4.8.0-29-generic with # apt-get install linux-image-4.8.0-29-generic That was the latest update available in the repo at the date. It installed successfully. After reboot the Xorg process was using >80% CPU and the computer was even more sluggish than a Windows Vista running in an Intel 80386 (5 seconds delay for a typed char to appear on screen in console). There is no need to be an Ubuntu expert to conclude that just updating the Kernel is not enough to solve the problem. Maybe I'm missing some extra configuration or also the X-Server/lightdm daemon must be updated accordingly. Also I'm differentiating Xubuntu from legacy Ubuntu because it affects Xfce and Unity.
