Either your BIOS does something very weird with your disk when OS commands it to power off (unlikely), or your system is set up in a way where there is no visible output when X is killed, but the system (Linux) is still running (shutting itself down). Some distributions get fancy ideas about "not scaring users with this text output scrolling up at boot & shutdown". This has nice side effect of users not noticing any potentially useful messages at boot or shutdown. :( -- vda -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
