![在终端中调用 unity 会破坏 X 会话中的 unity](https://linux22.com/image/1104716/%E5%9C%A8%E7%BB%88%E7%AB%AF%E4%B8%AD%E8%B0%83%E7%94%A8%20unity%20%E4%BC%9A%E7%A0%B4%E5%9D%8F%20X%20%E4%BC%9A%E8%AF%9D%E4%B8%AD%E7%9A%84%20unity%20.png)
我对 Ubuntu 完全陌生。我刚刚安装了 Ubuntu 11.04,它运行良好。我进入终端并输入unity
,屏幕一小会儿就变得很混乱,然后我的桌面就变成了我讨厌的经典桌面。现在,我该如何回到 Unity?... 我重新启动并在选择用户名时查看屏幕底部的选项,但没有显示 Unity,我选择了Ubuntu
,因为其他选项在其“描述”中包含 Classic。我还进入终端,unity
再次输入以查看是否可以恢复它,结果相同,但在输出中,它是这样的:
unity-panel-service: proceso no encontrado //PROCESS NOT FOUND, i use Spanish

答案1
当您说“我进入终端”时,您是指 Windows 内的虚拟终端吗?还是真正的文本终端,如 Ctrl-Alt-F1 等?
如果您选择后者,那么返回现有 Windows 桌面的正常方法是按 Alt-F7 或 F8 或任何正在运行的 X。请注意,返回 X 时不需要控制键。
注意:我从未使用过或见过 Ubuntu 11.x,我自己仍在使用 9.04。

@Terry 似乎是对的。
在 Ctrl-Alt-F1 tty 中调用unity
将产生以下输出,并在 Ctrl-Alt-F7 中中断正在运行的 unity (2d) 会话:

看起来您缺少 --replace 选项 - 登录时,按 Alt-F2,然后在框中输入“unity --replace”(不带引号)并按 Enter。如果框未出现,请尝试从经典会话中执行此操作。
