gnome keyboard and mouse are extremely slow with ASPEED graphics controllers

The gnome desktop keyboard and mouse on the server are extremely slow responding with many systems. This includes several broadwell/haswell systems as well. All of these system use ASPEED graphics controllers; using sles 15 beta/rc releases.

The graphics slow response happens before it is even logged in.

If you change the login to "Gnome on Xorg" during login, the slowness problem is solved.
