To expand on what Sam said a little, everything that the Wayland compositor does is being done now by the window manager, only it is being done in a far less efficient way because the drawing is done into regular-memory buffers instead of directly into video memory where the GPU can accelerate it, and it is all mediated by several trips through the X server instead of being done directly in the client process. If you had input methods before, you will have them then. It would be client side, like most all other input processing. I am hopeful we can do them in a way that is not bolted on to the side. I continue to think that just a little shared state would be very helpful. The new way gets video device drivers down to lean and mean, doing the things that device drivers should do: you know, bus enumeration, programming the registers. Get them out of the business of implementing anything else at that level. There is little point in having a lot of device drivers if they are for hardware that is all in scrap heaps. We have, I think, over the last week gotten the Big Three video drivers all functioning. Nothing stops someone from writing a DRM driver for a piece of hardware that has an existing X driver if one were needed; and it will be very much simpler than the X driver. If remote clients is your thing, instead of forecasting doom because the old way may not work any more, first off, nothing stops someone from writing a thing that listens on port 6000 and acts just like a remote X server only it is a Wayland client, and second off, nothing stops someone from redesigning and rethinking what the proper remote protocol is, using modern encryption and compression techniques and whatever else is needed to get a VNC like solution that performs well and is secure. Let's not penalize every local client in order to get remote clients. I encourage everyone to relax, pay a little less attention to the day-to-day details, and let the development go on. In a project of this size, not everything can get done first, and it is still very early. It may not be obvious what is scaffolding and what is done, but I think we have the best available people on the planet working on this and paying attention to it, and I am confident it will be polished until it comes out good in the end. _______________________________________________ wayland-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/wayland-devel
