It is my understanding that is not true. VNC is an entirely bitmap update protocol. RDP on the other hand allows drawing operations to be sent. Unless I am mistaken X11rdp intercepts X protocol drawing operations and translates them into RDP drawing operations. Consequently X11rdp will in theory always outperform anything based on VNC in terms of bandwidth utilisation, CPU and memory overhead. Basically the vnc-rdp thing is a nasty horrible hack to get something working and should only be viewed in those terms and seen as a dead end in terms of development. > > > Are there any plans to modernise X11rdp to work with newer Xorg trees, > > and, if so, where? > > Don't know.
