Many people use remote desktop apps like VNC, NoMachine, x2go etc with Ubuntu.
With Ubuntu 12.10 Unity2D is being dropped.
Gnome has already announced that with Gnome3 they are dropping "gnome-fallback".**
Unity3D and Gnome 3 are designed to work with real 3D hardware, and use the OpenGL library to send graphics commands directly to the video adapter, where data is rendered and shown on the physical display.
This will basically rule out using Unity3D or Gnome3 for "cloud" desktops as no cloud servers (AWS, Rackspace et al) I know of provide a physical 3d graphics hardware or a physical display.
Can anyone advise as to what thoughts are being given to how someone in the future will accomplish remote desktop under the Unity3D or Gnome3 ?
They answer can't be .. install xfce etc. as that would seem to be forcing users to choose a different desktop than they might use normally.
Is Canonical or anyone looking at what kind of solution there might be to this problem.
It seems to me that there is time to come up with a solution to this before it breaks many current compute use-cases.
