我 5 个月前购买了三星 EVO 850 SSD（256 GB），但启动时间一直让我苦恼不已。
我的电脑：
- 华硕 ROG GL752VW
- 处理器：英特尔酷睿 i7-6700HQ
- 显卡：Nvidia GeForce GTX 960M
- 内存：16GB DDR4
- 存储：256 GB SSD / 1 TB HDD
我在 Windows 10 和 Ubuntu 17.10 之间进行了全新双启动。我首先毫无问题地安装了 Windows 10（200 GB SSD）。我尝试进入 Windows 10，只需等待 4 秒钟即可开始配置系统。然后，我启动到 Ubuntu Live，并在 Windows 10 旁边安装了 Ubuntu 17.10。
我在 Ubuntu 上尝试关闭或重启 Nvidia 时总是遇到问题，因此我编辑了 /etc/default/grub 并将以下内容更改
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
为
GRUB_CMDLINE_LINUX_DEFAULT=""
此后，我安装了 Nvidia 驱动程序：
sudo apt-get purge nvidia-*
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-387
问题是，当我进入 GRUB 时，我选择了 Ubuntu，然后出现了一个持续 15 秒左右的紫色屏幕。我将粘贴一些命令的输出，看看你是否知道发生了什么。谢谢大家。
