Gnome on RHEL 7 requires OpenGL acceleration. You can get it to work by installing VirtualGL 2.4 or later and running the WM in VirtualGL by using 'vncserver -3dwm'. However, what I would do instead is either use KDE (which should work fine with TurboVNC 2.0) or install Mate Desktop using EPEL. Mate is a fork of the old Gnome 2 environment that doesn't require 3D acceleration.
