To post a comment you must log in.
The error 13 is in fact EACCES (Permission denied). This is normal for non-root users trying to start Mir.
You need to have DRI device permissions, which should have been set for you indirectly via lightdm. If you didn't come in via lightdm then you either need to be root or...
sudo chown $USER /dev/dri/*
