The Xorg log is showing like setting up for a
500X285

screen size so there must be something wrong with the drivers.

What's wrong is that Xorg sets whatever screen size is required to make the
resulting logical DPI 96. If you desire an accurate DPI, work is involved to
override this insanity, which is designed to emulate Windows and accommodate
ineptly designed web sites. It's not just Xorg either. Upstream, Gnome forces 96
too, unless an appropriate overriding config is applied by the local admin. The
Gnome insanity has been patched out of openSUSE, but not Xorg's.

        OK thanks...someone reported a bug on the archlinux bugzilla

FS#56994 - [mesa, xorg-server] mesa 17.3.1-2 and xorg-server-1.19.6-2 fail to start on AMD kaveri

    This seems to be the problem I am having....there are some suggestions there about changing the xorg configuration..

I am wondering if I should try these or file a bug report...
