IR ,how to set it up?

by installing lirc over the existing xbian lirc package you have obviously overwritten the lircd.conf. the debug message from your shell doesn't look that good as well IMO... "Remote control support has been disabled". you should better use the btrfs-snapshot to go back to a previous version and use the default lirc package which should work fine. (at least it does for me)
