This was tested on F18.
Xvnc: rrmode.c:265: RRModeInit: Assertion `num_modes == 0' failed.
1. Start an Xvnc server - for example:
$ /opt/thinlinc/libexec/Xvnc :1 -query localhost -geometry 1024x768 -depth 16
-ac +extension Composite passwordFile=~/.vnc/passwd
2. Connect to Xvnc server, e.g.:
$ /usr/bin/vncviewer localhost:1
3. Launch a Gnome Shell session on the Xvnc server. e.g.:
$ DISPLAY=:1 dbus-launch gnome-session --session=gnome
