My problem is that I'm a "install it and forget it" person so I don't
have much experience poking around in xorg.conf.

AMD helpfully provides an uninstall script, which seems to have worked
but may have left some items installed (uninstall log was decidedly
unhelpful).  It left me without an xorg.conf at all so the driver
picked a generic config.  Problem is that I have displays on both DVI
connectors and the HDMI connector.  The default doesn't see that.  I
tried using aticonfig to generate an initial config but that leads to
no display and a warning about "kernel module (fglrx.ko) may be
missing or incompatible ".

Really not sure where to go from here which is why, initially, I'd
installed all the AMD/ATI stuff (including their GUI control panel).

But I can confirm that the AMD drivers aren't very good.  The problem
with konsole exists when I run Opera, too, in addition to Chrome.  And
I'm really tired of Firefox.  :-)
