This is currently an issue for Lubuntu, because, if i understand correctly, we are going to replace an X + openbox (without composite) with a Mir + XMir + composite windows manager (?). Considering the very bad performance on some of our target hardware running under a composite manager, I'm quite worrying about the performance difference. The difference between Unity + X and Unity + XMir + Mir may not be so different, I can't say the same for Lubuntu. However, Steve Langasek confirmed on a previous mail that X will remain for 14.04 for the time frame of the LTS, and I hope it will still be the case with this change. We currently plan to ship X only by default for 13.10 and 14.04 for Lubuntu, with eventually an option to test XMir, to prepare the future.
