Don't think this is a replicated question. Ubuntu 13.10 x64 cannot shut down properly, pressing esc stuck at purple screen:
Broadcast message from root@ubuntu-laptop (unknown) at 19:51 ... The system is going to power off NOW! Shutting down SmartLink Modem driver normally Unloading modem driver from kernel ... none found. speech-dispatcher disabled: edit /etc/default/speech-dispatcher * asking all remaining processes to terminate ... [OK] * killing all remaining processes ... [fail] modem-manager: <info> Caught signal 15, shutting down [OK] * deactivating swap... mount: / is busy * will now halt
And it hangs there and doesn't shut down. Please help and please tell me if more info needed!
