自从我升级到 15.04 后，我就失去了终端。我无法再使用 xterm，因为 xterm 根本就不如基本的 Ubuntu 终端好用！
我如何取回它？
当我单击终端图标（启动器）时，它会闪烁一下，好像发生了什么事，但启动从未发生（即，我没有终端）
我如何取回它？
编辑：我是一个普通用户，但我接受了通过 strace 运行这个的建议......这里我看到的是一大堆我无法理解的机器人呕吐物。
由于 30k 个字符的发布限制，我附上了机器人呕吐的后半部分：

答案1
运行以下命令：
sudo apt-get purge gnome-terminal
sudo apt-get install gnome terminal
这将删除它（如果它确实存在）并用新副本替换它。
答案2
