That would be separate from the display driver, which creates the actual video signal. While Weston has GL-renderer using OpenGL that it uses by default, it also has Pixman-renderer using the CPU. For most backends, you can choose that with --use-pixman, but it naturally also disables accelerated OpenGL for apps. The RDP-backend uses only Pixman-renderer currently. > > > > What's the reason for your new backend and do you intend to send it > > upstream, if I may ask? > > Reason would be to go around the problems experienced with the various RDP > clients I've tried.

It's very good to talk about it before-hand, so you will know what to expect from the upstreaming aspect. Right now I cannot say if a new remoting backend is welcome or not, if the use cases are essentially the same as for RDP-backend. Although, I suppose why not, the RDP-backend has been pretty easy on maintenance too, but it has a dedicated person taking care of it when something breaks (usually due to freerdp breaking its API). > > > > There are various remoting efforts going around, mostly in the > > automotive industry. > > Mmmh.

Maybe Daniel Stone could say something? I must confess I don't really keep track on downstreams much. Thanks, pq
