A还清除了与NVIDIA相关的所有软件包。我不得不说，在Kubuntu安装之后，它已经看到了它，但在这个问题出现几天后。

对不起，我的英语。如果你不明白的话，我可以重写。:)

您的lspci输出显示您目前正在使用集成的英特尔图形解决方案。

安装最新稳定的NVIDIA驱动程序，从专有的GPU驱动程序PPA中支持GT 740。

在安装新的驱动程序之前，请卸载之前安装的所有NVIDIA相关软件。

打开终端并执行：

sudo apt-get purge '^nvidia.*'  
sudo apt-get purge bumblebee
sudo reboot

然后通过执行以下命令，从长寿分支安装最新的稳定NVIDIA驱动程序：

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-352 
sudo reboot  

如果您使用的笔记本与混合图形解决方案安装Optimus支持以及。

sudo apt-get install nvidia-prime

要在英特尔和nvidia图形之间切换，请打开NVIDIA服务器设置->主配置文件。

切换到NVIDIA之后，再次运行sudo，输出显示您的NVIDIA GT 740 GPU。
