O visualizador do TightVNC fecha erradamente após iniciar um programa

Question

Eu tenho o Ubuntu 14.04 e conecto com o visualizador TightVNC do Windows 10. Ele parece ir bem, até eu iniciar um programa, por exemplo, um Internet Explorer. Em seguida, ele só fecha, com a mensagem: "Conexão foi fechada com graça".

Tentandoreiniciá-lo,nãofuncionará.Comoeufico:
