Linux Linux Magazine has a profile of Daniel Fore and the Elementary project. Elementary is a Linux distro that's committed to a clean and simple user experience, but it's more than a distro - it's actually a multi-pronged effort to make improvements to the user experience for a whole ecosystem of components, including icons, a GTK theme, Midori improvements, Nautilus, and even Firefox. The work that elementary is doing isn't limited to their own distro, and some of their work is available in current, and perhaps future, Ubuntu releases. The results are really striking, and I think it's probably the handsomest Linux UI I've ever seen.

RE[5]: Improvements to Linux?

Yes, there are methods for recreating the state but they are not necessarily that simple. Clients can, for example, reconnect to the server and replay actions that lead to the lost state. This might be hard to do if there is a lot of server-side state (like in legacy X applications) or if the session was migrated to a different resolution/color depth/dpi/... screen.

So, we need to keep the information on the client side as well. And that's what, as you pointed it out, modern toolkits do. The price to pay for it is that all the drawing operations are now being done in software (in the client) and Xserver and graphics card acceleration are only used for blitting the resulting images onto pixmaps and applying some 2D/3D transformations. Yes, it works well (at least locally) but it is not the model X was designed for. In fact it works by deliberately avoiding legacy Xserver features.

The limitations are that this solution works slowly over network (or doesn't work at all if the client/toolkit uses XShm only) and is limited to applications written with new toolkits leaving e.g. $$$ Motif apps behind. That's what I meant by "performance hit" and "changing the clients".
