我最近使用 gparted 来增加我的 ubuntu 分区的大小。现在，启动时间非常长。当我运行时，dmesg我得到（如果您想要全文，请告诉我。以下只是某些部分）

有几个大峰值。一个从 1.99 到 32，另一个从 35 到 123，还有一个从 170 到 217。我看了一些帖子，比如这个调整分区大小后启动速度变慢和Ubuntu 15.04 启动非常慢和蓝牙是导致我的 Ubuntu 16.04 启动速度变慢的原因吗？也许这也是我的问题。但在做任何愚蠢的事情之前，我都想听听别人的意见。
另外，当使用 gparted 时，我确实遇到了一个错误，其中交换分区的文件系统列未知，我必须右键单击 - > 格式化为 - > linux-swap。
另一件有用的事情（也许）是我按照ASUS ZenBook Flip 14 上的 Nvidia 卡有时会启动到紫色屏幕（接受的答案）所以我将其添加quiet splash dis_ucode_ldr到 grub 中。
