系统进去之后只有壁纸鼠标，其他的东西都没有。鼠标的点击事件和键盘均不响应
在.profile文件下添加了项目开机运行gnome-terminal。总算就通过虚拟终端在图形环境下打开其他的软件。但是没有标题栏。没有unity左侧的快捷栏。pupmemu属性的界面如鼠标右键，均不能显示。
打开CCSM开启unity plugin还是没有好转。

求救……急救

正在升级中。估计你用了闭源驱动？

開機選單 選擇升級以前可以開機的 linux kernel 版本
看看能否順利開機

如果沒有出現開機選單
開機載入 Bios 後 立即 按住 shift 或 esc
多試幾次 因為時間要抓得住在開始載入硬盤之前

还是用3.16的内核吧。早上升级了3.18.0内核，居然初始化过程中不支持USB了，支持VirtualBox 4.3.20，不过经常崩溃。
PS：我使用USB3硬盘安装ubuntu,上下班带个硬盘就OK了。

你是如何解决两台电脑上驱动不一样的问题的?我也在移动硬盘上安了一个,在家的电脑上开启不了无线,显卡也进不了兼容模式非常郁闷

全部只安裝 linux-kernel 打包在內的 開源驅動

在单用户模式下面删除了ati显卡驱动之后可以开机了。但是显示器的分辨率就不对了。安装开源驱动后，笔记本的1366＊768屏幕只能显示1024＊768的，但是使正常。安装闭源驱动却只能显示壁纸。

使用 randr 關鍵字 輸入本論壇 上方 問答集 右方 搜尋框
可以找到以前文章 增加/設定/儲存 屏幕分辨率

不好意思，没有找到这个文章。你是指用xrandr命令的话，我已经试过了，但是没有成功。系统显示的显卡就不对是Gallium 0.4 on llvmpipe (LLVM 3.6, 256 bits)……

Gallium 0.4 on llvmpipe (LLVM 3.6, 256 bits) 不是顯卡型號 或 顯卡驅動
只是開源驅動裡的功能模組
http://nouveau.freedesktop.org/wiki/MesaDrivers/
The drivers for card families
The Gallium3D-based drivers are all compiled into nouveau_dri.so
http://www.mesa3d.org/llvmpipe.html
The Gallium llvmpipe driver is a software rasterizer that uses LLVM to do runtime code generation.

那我应该去装个intel或amd的驱动。

可以的话还将希望给个帮助。分辨率还是不对。电脑是AMD的独显和intel的集显显卡

把下面指令 複製 貼進終端機 執行
1-1. uname -r
1-2. sudo lspci -knn
1-3. sudo lshw -numeric -class video
把結果直接 選取/複製 貼上來
不必擷圖

1. 雙顯卡
沒有作用中的顯卡驅動

2. 建議
2-1. 從開機選單中 選擇升級前的 Linux Kernel 版本 登入
如果 開機沒有顯示 開機選單
開機 立刻按住 esc 或 shift 鍵 直到 出現開機選單
2-2. 從開機選單中 選擇 Recovery Mode 登入

3. 目的 補救

4. Ubuntu 15.04 目標是 3.19
