The developers of the Ubuntu spin-offs Kubuntu and Lubuntu have indicated that their 13.10 editions will not include the Mir-displayserver. Canonical has already decided for its self-developed displayserver in Ubuntu 13.10.
The developers of Kubuntu and Lubuntu, respectively, KDE and LXDE as a desktop environment offer, however, nothing in Mir to see, and the displayserver provisionally left. The preference still goes out to the X.org Server. So let Jonathan Riddell of the Kubuntu Project to OmgUbuntu know that the Mir project of Canonical in his eyes, discord sows within the Linux community. Kubuntu will then also in the following releases for X.org choose.
From the Lubuntu camp sound similar sounds and both the 13.10 – if the 14.04 LTS-releases of Lubuntu will with X.org Server. This choice would be made because LXDE in combination with Mir’s performing more poorly than X.org Server. However, it must be in the long term may have a trial version of Mir will appear.
