我使用的是 Ubuntu 14.04（64 位），内核版本为 3.16.0-40-generic。我的 nvidia 是

这意味着它是 GeForce GT 650M。因此，我去了nvidia 搜索检查哪个 nvidia 适合我的笔记本电脑。我找到了版本 346.72。但是，当我安装它时。我无法登录我的电脑。当我登录时，它总是重复登录屏幕。我需要卸载它。然后它才能再次登录。我的问题是什么？如何解决？我也尝试过其他方法，例如
$ sudo add-apt-repository ppa:xorg-edgers/ppa -y
$ sudo apt-get update
# install the latest version
$ sudo apt-get install nvidia-current
但是它显示（注意我之前安装过 304 版本但我卸载了它）
nvidia-current is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
cuda-drivers : Depends: nvidia-340 (>= 340.29) but it is not going to be installed
Depends: nvidia-340-dev (>= 340.29) but it is not going to be installed
Depends: nvidia-modprobe (>= 340.29) but it is not going to be installed

nvidia-340-uvm : Depends: nvidia-340 (>= 340.29) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
更新错误：当我尝试卸载当前 nvidia 并安装新的 nvidia 331 版本时，它显示为

答案1
首先，我建议删除所有 nvidia 驱动程序。
sudo apt-get purge nvidia*
对于 Ubuntu 14.04，默认和首选的驱动程序是 nvidia-331。
可以通过以下方式安装
sudo apt-get install nvidia-331
您可以选择升级内核并安装更新的驱动程序。
升级内核到 3.19
sudo apt-get install linux-generic-lts-vivid
重启
然后从 xorg-edgers 安装 nvidia-346
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-346 nvidia-prime nvidia-settings
sudo add-apt-repository -r ppa:xorg-edgers/ppa
安装时查找错误。在大多数情况下，驱动程序运行良好，但这取决于安装的图形堆栈版本、集成适配器型号等。
如果驱动程序不工作且图形不启动，请按 Ctrl+Alt+F1，登录控制台并运行
sudo apt-get purge nvidia*
