No, it's not a bug in the sense that we only require *an* implementation of the Unity.Application module, and the Mir one is preferred, as it's the only real implementation. So installing just unity8 won't get you the fake one that will let you run under X11 - you need to install it manually. We could improve the error message, that's for sure.
As for the missing lightdm session, it's the first I've heard, did you reboot after installing it? Can you please file a bug against unity8 -desktop-session for this please? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1426713 Title: libqpa-mirserver.so does not exist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1426713/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
