我使用的是正确的nvidia驱动程序吗？

我在配备Nvidia GTX 950M显卡驱动程序的HP Envy Slim笔记本上使用Ubuntu Desktop 14.0.4和Linux内核4.2.5。 一切正常，但我想确保我使用正确的图形驱动程序？

我使用以下步骤来获取它：

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

这是Xorg.0.log

Answer 1

是的，您正在使用Ubuntu专有的Nvidia驱动程序推荐的。

而且它与Nvidia推荐的最新稳定驱动器相同。

其他专有驱动程序被错误地标记为“开源”。 它们是beta 专有的。 你也可以尝试一下。

358不是测试版，但它不是LTS分支。

Answer 2

如果您希望从第三方驱动程序中清除您的系统，Canonical无法检查有问题的代码片段：否。 您已安装第三方版本，在这种情况下，应使用“nouveau”。

361开源版本比您现在使用的版本更新。 您可以尝试安装361并查看它是否与您当前的一样好。

如果你想保持你的系统纯净，或者你想要使用更新的版本，答案是否定的。 但是，如果你现在的工作方式有效。 使用更新的版本总是一个好主意，但如果这些工作不如你现在使用的那么好……坚持使用更有效的方法。
