无法让nVidia驱动程序使用16.04，登录后立即注销
我已经在4月18日星期一安装了Ubuntu 16.04 beta 2。 当我尝试安装nvidia-current，nvidia-361或者jockey安装的版本时，lightdm无法完全启动或者我无法通过登录窗口。 当我登录时，lightdm.log报告我已成功登录，由于某些原因它显示我已设置的音量然后它返回到登录屏幕。
我有一台带有Optimus技术的混合nVidia / Intel显卡的笔记本电脑（我不需要GPU切换，但我希望nVidia能够正常运行），确切的nVidia型号是GT630M。
这是Xorg.0.log：

现在，我被nouveau / intel困住了，这有时非常有限。 知道会发生什么吗？ 也许丢失的/etc/X11/xorg.conf文件可能是问题所在，但我不知道它为什么不存在。
注意：从16.04的主要版本开始，错误已从未检测到设备 且未找到任何屏幕更改为无法初始化GLX扩展（未找到兼容的NVIDIA X驱动程序） 。 现在，lightdm启动更容易，但我仍然无法通过登录屏幕。
进一步编辑：我一直禁用安全启动。 我已经安装了添加了nvidia驱动程序的bumblebee（尝试过304和340），但它无法使用nVidiavideo卡启动程序。 进一步的调查显示nvidia的modprobe由于这样的事情而失败：
could not insert 'nvidia': Unknown symbol in module, or unknown parameter (see dmesg)
我尝试了更高版本的驱动程序（361），但它仍然失败了。 我在某处看到i915驱动程序造成了这个问题，但我没有安装它们。
更多信息：这似乎是根本原因。 随着nVidia驱动程序与其DKMS模块一起安装，我无法将其插入内核（使用modprobe）。 报告的错误是它无法找到一个特定的PCI端口（根据lspci它应该是一个端口）。 我没有保存确切的措辞，对不起。
由于社区的共同努力，我设法让它运作起来。
首先，到达终端（按ctrl – alt – f1如果你无法登录，或通过恢复模式）。 安装nVidia驱动程序版本364（包nvidia-364）。
sudo apt-get install nvidia-364
如果找不到包，请添加包含它的ppa：
sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt-get update
重新启动计算机。
sudo reboot -i NOW
如果您没有被回到登录屏幕，但只能看到您的背景，请强制它重新创建您的用户设置（保存备份）：
sudo mv ~/.config/dconf/user ~/.config/dconf/user.old
然后，重启lightdm：
sudo service lightdm restart
如果你想安装bumblebee，请注意它的配置设置不好，即使没有安装nvidia-current，它也会寻找nvidia-current。 我编辑它来引用nvidia-364（因为安装的文件在/ usr / lib / nvidia-364中），我能够用optirun启动程序。
我在Nvidia和16.04遇到了一些问题 – 终于搞定了。 在一个nvidia gtx980m（华硕G752游戏笔记本电脑） – 我建议你确保你尝试从命令行安装，而不是简单地从gui …启用专有驱动程序…（继续阅读）
我没有得到描述的引导循环，但是我得到了低分辨率（800×600）并且它根本不起作用 – 但是新的一个很好。 （全部通过司机gui）
我终于通过“sudo apt-get install nvidia-xxx（在我的情况下是361 – 也尝试过352）安装到命令行并安装了相同的软件包
它然后正常安装，但在终端弹出一个菜单，表示“UEFI”安全启动已启用，你必须输入一次性密码才能在重新启动时禁用它“启动进入不安全模式。所以我做到了。
完成后，在重新启动时 – 确实弹出了UEFI窗口菜单，我选择将启动模式更改为不安全。 然后它问我几个字符“按位置”（EG …输入字符6，然后键入字符4等），然后每次输入。 最终在3-4个字符后，它允许我关闭安全启动。 然后机器再次重新启动，并说“启动不安全模式”，然后驱动程序工作。
还发现当安装virtualbox时也通过synaptic，但至少它工作并使用该方法弹出一个菜单….
希望有帮助……
如何恢复桌面？
通过在登录屏幕中按ctrl – alt – f1 ，您可以转到命令行。 使用您的用户名和密码登录。 在此命令行中，您可以通过运行以下命令来卸载nvidia驱动程序：
sudo apt remove nvidia-361 sudo apt autoremove
请注意，nvidia的特定版本可能会有所不同。 您可以通过运行apt search nvidia | grep installed | grep nvidia找到已安装的nvidia驱动程序的版本 apt search nvidia | grep installed | grep nvidia
或者如果您只是想在不删除nvidia驱动程序的情况下切换到Intel显卡，请运行
prime-select intel
但我想用我的nvidia卡！
您可以尝试以下几种方法：
禁用安全启动
正如@biff所说，安全启动可能会阻止nvidia驱动程序加载。 要禁用安全引导，请使用命令行安装nvidia驱动程序。 Ubuntu会要求您在安装过程中禁用安全启动。
安装旧的nvidia驱动程序
安装旧的nvidia驱动程序可能会解决一些问题。
我也有同样的问题。 运行Ubuntu 16.04。 英特尔HD4600和Nvidia 765M。 试过上面的所有建议。 它在使用终端安装时有效，但是如果我使用多个监视器，它就会出错并最终进入启动循环。
我读过有人建议测试版驱动程序364xx有效。
就我而言，只需安装nvidia-364解决了这个问题。 我的配置是运行Ubuntu 16.04的华硕H170 + Intel i7 6700 + 32Gb DDR4上的NVidia GTX 750Ti。
我有一台GTX980，升级到16.04（从15.10开始）后无法登录。 删除nvidia：
sudo apt-get purge nvidia*
并登录。它工作但分辨率限制为800×600。
以下步骤解决了我的问题：
- 重新安装nvidia：
sudo apt-get install nvidia-361 - 重新启动，转到BIOS并禁用安全启动
感谢biff提示禁用安全启动:-)
