问题

在昨天安装了常规系统更新并重新启动后,突然缺少启动器和菜单栏

我现在能够做事情的唯一方法是,当我输入unity --debug到终端中时,我可以使启动器和菜单栏重新出现(暂时):


~$ unity --debug


unity-panel-service stop/waiting


unity7 stop/waiting


unity-panel-service start/running, process 5114


[Thread debugging using libthread_db enabled]


Using host libthread_db library"/lib/x86_64-linux-gnu/libthread_db.so.1".
