Just down-loaded the ISO (08/13/13 Version: 0.0.9r970) from http://vanir.unit193.tk/mir/. I used it to install on my rig described below. Then, I performed an apt-get update and dist-upgrade to make sure that I was testing an up-to-date system.

Summary:

(1) While the compositor did try to come up, it gave up and returned an exit code of 1 according to the lightdm.log. The unity-system-compositor.log contained the following:

   ERROR:
   
/build/buildd/mir-0.0.9+13.10.20130813/src/server/graphics/gbm/gbm_display_helpers.cpp(305):
   Throw in function void
   mir::graphics::gbm::helpers::GBMHelper::setup(const
   mir::graphics::gbm::helpers::DRMHelper&)
   Dynamic exception type:
   
boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error>
    >
   std::exception::what: Failed to create GBM device

(2) Lightdm handled the exit code by starting an X session as a replacement.

The resulting Lightdm on X on Linux kernel 3.11.0-2 is quite stable.
Queries or further testing?
