问题描述
我刚刚安装了一个新的 ubuntu 16.04 ，\nfresh install clean ，登录的第一件事也是我做的唯一一件事就是为 nvidia 选择专有驱动程序 361 ，重新启动机器。\n在重新启动后我可以登录但没有显示统一，我仍然可以右键单击并打开终端，尝试了很多答案：\n link1 \n link2
没有帮助，我很沮丧，启动到 USB 并重新安装它，这次我尝试了 340 个驱动程序同样的问题。\ni 的意思是看在上帝的份上这是 16.04 LTS。\ni 有双显卡 nvidia gt 740m，intel 建立在华硕笔记本电脑。
grep “EE\\|WW” /var/log/Xorg.0.log 的输出：

最佳思路
我还安装了 Ubuntu 16.04，在新的高清上全新安装，一切正常，直到我切换到 NVIDIA 驱动程序。重新启动后，我无法通过登录屏幕。对我有用的解决方案是禁用安全启动。
当卡在登录循环中时，我切换到控制台 Ctl+Alt+F1 ，重新启动并禁用 UEFI 中的安全启动。现在一切正常，安装了 nvidia 驱动程序。
次佳思路
我也有这个问题。我只是在控制台中运行它(按 Ctrl + Alt + F1 ，在登录页面中显示第一个虚拟 tty)：
sudo apt-get purge nvidia*
在此之后，重新启动，然后我可以登录。之后，我先安装了intel驱动，然后安装了nvidia-361。
这些是我遵循的步骤：
-
sudo apt-get purge nvidia* -
重新启动\n(现在我有 noveau 显示驱动程序工作)
-
sudo apt-get install intel-microcode -
sudo apt-get install intel-gpu-tools -
重启(为了测试，一切正常)
-
sudo apt-get install nvidia-361(我认为 nvidia-current 是更好的长期选择)。 -
重启
现在我有了这些(对不起，它们是西班牙语)：
第三种思路
找到了解决方案(这次是真的)，\ni 决定成为一名 ubuntu 专家，所以我去谷歌并输入：
\\n
debug ubuntu
\\n
然后它给了我页面 Debug 并且我选择了统一。\在我需要做的一些部分中：
$ unity --advanced-debug

Function "_exit" not defined.
Make breakpoint pending on future shared library load? (y or [n])
[Answer yes (y)]
(gdb) run
[ and when compiz/unity crash, do...]
(gdb) bt full
[ then CTRL-D or re-run compiz to continue working ]
(gdb) run
运行此之后，我注意到错误：\ncompiz (core) – 错误：插件 ‘opengl’ 未加载。
我在谷歌上搜索了这个错误，它给了我这个线程 Unity missing? Can’t see top or side panels，这里的答案有效。
