Unity launchers e bar desapareceram e unity --reset mostra um erro

Question

Estou tendo um problema com a união. Eu lancei o Movie Player com o QNapi (aplicativo para baixar legendas de filmes) e de alguma forma o Unity caiu e desapareceu deixando apenas as janelas abertas sem os lançadores, barras de título e barra superior da unidade.

Depois eu vou para Ctrl + Alt + F1 e tento para unity --reset Eu recebo este erro

O que eu posso fazer (além de reiniciar)?

EDITAR

A inicialização de Unity Panel do compiz também não ajudou.
