当我启动时,我可以正常进入登录屏幕,然后登录后,我得到一个带有墙纸和鼠标光标的屏幕,但没有菜单,没有破折号,ctr + alt + T 没有任何作用,单击鼠标没有任何作用。我尝试使用 ctrl + alt + F1 - F6 获取文本提示,但它们将我带到一个完全空白的屏幕,没有提示,ctrl + alt + F7 将我带回到墙纸和光标。发布的所有其他解决方案都需要我进入终端窗口,但我无法进入。
发生这种情况时,我从 14.10 升级 - 升级似乎正常进行。这台机器最初使用的是 10.04,但每 6 个月升级一次,没有出现任何问题......直到现在!
我可以进入恢复模式,但真的不知道该怎么做才能修复它。
我的机器是华硕笔记本电脑,配备 radeon HD6320 显卡和 AMD brazos E450 处理器。
我已经创建了 15.04 的可启动 DVD,并且运行正常!
我的 .xsession-errors 文件有一些奇怪的条目 - 有人知道它们是什么意思吗?

答案1
这是一个不太可能的问题,但我遇到了和你一样的问题,我花了一个小时反复试验才修复它。我还没弄清楚原因,但 Unity 设置可能搞错了。
您需要启动 compiz 配置设置工具。我不知道如何从命令行启动它,所以我启动了一个 cinnamon 会话,在那里我可以启动设置工具。在设置工具中,我坦率地说,弄乱了一点。选中并取消选中 OpenGL 插件和 unity 插件。我认为后者可能是让它工作的原因,因为它向我发出警告和冲突。
此后,我注销并重新登录,Unity 又恢复了。
答案2
我遇到了同样的问题,我所要做的就是:
sudo apt-get install unity && unity
我的桌面立即就修复了。
答案3
我也遇到过同样的问题,但升级后就没再出现过。我早上关闭了笔记本电脑,今晚启动后突然没有了窗口装饰、仪表板和菜单栏。
根据 Leonard Broman 的建议,我打开了 CompizConfig(幸运的是,右键单击空白桌面仍然会给我一个上下文菜单,其中包含打开终端选项)。结果发现所有插件(Composite、OpenGL、Unity 插件、Desktop Wall、Grid 等)都因某种原因被禁用了……我只需重新启用它们,图形用户界面即可再次正常显示。
