我正在使用 ubuntu 14.4.0 64 位。昨天我安装了 GTK、Glibc 及其依赖项。包括，
- libffi-dev、libcairo2-dev、libtiff-dev、flex、bison、xorg-dev、libatk-bridge2.0
最终安装了 glibc 和 GTK 3.10。[编辑：] 有些是通过包管理器安装的，有些是从源代码安装的，./configure我make install不记得哪个属于哪个类别。
重新启动后，我收到一个消息框，
System running in Low Graphics mode
我已经尝试了所有软件包的安装和卸载，但没有任何效果。我可以访问终端。所以我尝试了“启动“。现在我以不同的方式获得了 GUI，
1) 它没有关闭[X]或最小化[-]按钮。 CTRL+Q 用于退出。（ALT-f4 不起作用） 2) 可以通过按 ctrl+alt+T 打开终端。但不能写入任何内容 3) VLC 媒体播放器可以打开，但没有关闭按钮。
我想恢复我的所有数据。所以我准备安装或卸载任何东西。所以请帮我恢复我的 GUI。我试过了，
- 安装 gdm
- 光调制
- nvdia-当前
- Ubuntu 桌面
但重新启动后我收到相同的警告“系统以低图形模式运行”
我还记得，之前我在 fedora-20 中安装 GTK 时丢失了 GUI。尝试了很多次。然后转到 Ubuntu。GTK 有什么问题。我该如何恢复我的系统。

很可能是根分区空间不足。因此，使用以下命令检查是否有足够的可用空间：
DF-H
可以通过删除临时文件、不需要的文档、软件包来释放空间。最简单的方法是通过以下方式卸载 vlc：
sudo apt-get 删除 vlc
