Thanks for the heads-up, Malcom. I got a kernel update at about the same time as your posting, so I think I'll wait until the next kernel update before reverting mine. Though I do have VNC working now so can get at the SUSE GUI from my Mac. I'm liking it more and more! About time to install a SSD or hard disk copy attached to my Pi-3. It really performs quite well, even on the microSD card; should be quite respectable with a USB-attached drive (which is how I run Raspbian on my other Pi-3).

Thanks again for your help on this: it really made a difference.
