Here's another attached settings.txt this time with the relevant parts
of the displayprofiles table, and with the dross of settings for other
frontends removed. I still don't have the xdpyinfo output. I have
xdpyinfo on another machine, and I tried xdpyinfo -display lithe:0
but that didn't work.

Mike, if there's nothing in these settings that looks like the
cause, that would still be useful to know.

Cheers,
