Ubuntu GNOME 16.10 启动非常慢

Ubuntu GNOME 16.10 启动非常慢

我最近从 Windows 10 转到 Ubuntu,发现启动速度明显下降。我尝试在网上寻找解决问题的方法,但失败了。

systemd-analyze blame 

给我以下:

         22.181s plymouth-quit-wait.service
         14.209s snapd.firstboot.service
         12.125s dev-sdb1.device
         10.708s networking.service
         10.528s apport.service
         10.197s ModemManager.service
          9.015s apparmor.service
          5.811s grub-common.service
          5.544s speech-dispatcher.service
          5.458s irqbalance.service
          5.455s systemd-udevd.service
          5.290s systemd-logind.service
          5.144s gpu-manager.service
          5.143s pppd-dns.service
          4.914s avahi-daemon.service
          4.516s NetworkManager.service
          3.739s accounts-daemon.service
          3.182s polkitd.service
          3.081s thermald.service
          2.711s systemd-tmpfiles-setup.service
          2.175s rsyslog.service
          1.832s plymouth-start.service
          1.670s keyboard-setup.service

我只是 Ubuntu 的新手,因为我一生都在使用 Windows。我也只是一个中级计算机用户,所以这些行并没有给我太多信息

我还读到,我的问题可能与 fstab 文件中交换分区的 UUID 不匹配有关,但这不是我的情况。

sudo blkid

给我吗

/dev/sda1: UUID="7091fe2d-6f35-417e-ac8d-6378ece33b30" TYPE="ext4" PARTUUID="5812a99e-01"
/dev/sda2: UUID="681819bb-3063-4734-9a40-a0ada019cf99" SEC_TYPE="ext2" TYPE="ext3" PARTUUID="5812a99e-02"
/dev/sdb1: UUID="1b698478-f32d-4a9a-963c-8853331c6a74" TYPE="ext4" PARTUUID="ecfba038-01"
/dev/sdb5: UUID="257c98ed-10bd-4f5d-977a-2ae06639155d" TYPE="swap" PARTUUID="ecfba038-05"

我的 fstab 文件中有以下内容

# / was on /dev/sdb1 during installation
UUID=1b698478-f32d-4a9a-963c-8853331c6a74 /               ext4    errors=remount-ro 0       1
# swap was on /dev/sdb5 during installation
UUID=257c98ed-10bd-4f5d-977a-2ae06639155d none            swap    sw              0       0

先感谢您!
