Installing the tigervnc client did not make a difference. Still
failing
to start.
I know from using this on an f20 install on my build machine, by default tigervnc uses
xrandr's list of available modes to populate valid resolutions for vnc.
That is a bit strange, but that is how it is.
On the plus side xrandr lets you add your own modes by hand, which let me use a
nonstandard resolution I needed on my client device.
But if it won't start, that won't help yet.
How about trying making a fake xorg.conf with one dummy modeline in it so xrandr has
something to report?
