Ubuntu tty2的Smth故障

上次我设置了Ubuntu 14.10，效果非常好。它默认使用tty1控制台。但昨天晚上我改变了xbindkeys的设置。现在，我发现ubuntu是从tty2开始的，绑定键不起作用

要查看它，tty2-现在正在工作

root@stand2:/# systemctl status getty@tty2
getty@tty2.service - Getty on tty2
   Loaded: loaded (/lib/systemd/system/getty@.service; enabled)
   Active: inactive (dead)
     Docs: man:agetty(8)
           man:systemd-getty-generator(8)

tty1不使用

root@stand2:/# systemctl status getty@tty1
getty@tty1.service - Getty on tty1
   Loaded: loaded (/lib/systemd/system/getty@.service; enabled)

如何决定这个问题，我试了很多方法
