Subject: Testing desktop Mir/Xmir on 14.04

Hello all,

I've been running 14.04 development version for a while, and thought I'd have a 
look at the Mir/XMir packages and see how they're getting on.

I've installed unity-system-compositor and mir-demos, but unlike Saucy this 
doesn't seem to activate unity-system-compositor; there appear to be no 
additions to lightdm.conf.d.

I know that 14.04 will have X by default, and with 14.10 the goal is to have 
Unity 8 direct on Mir, but is there any interest at all in having us as users 
try out Unity 7 on XMir?  And if so -- how to get it up and running?

Thanks & best wishes,

     -- Joe

Joe,

Thanks for pointing that out. I'm not sure if it's an intentional 
change, perhaps mterry can answer. In the mean time I've logged a bug 
for it:

https://bugs.launchpad.net/ubuntu/+source/unity-system-compositor/+bug/1280924

I have seen some people like XMir in its old (saucy) form because 
amazingly Mir is much better at providing smooth page flipping than some 
native X drivers/DDX's. And plenty of people can confirm Mir provides a 
nicer X experience in some cases. Why this might be is an issue for the 
X drivers, but certainly it's nice to see Mir raising the bar in a 
strange little way. I would like to see it retained as an option to 
install too...

Sorry I can't explain why this change has occurred. But let's keep the 
discussion in the bug.
