短期修复
这是 Plymouth 启动画面。作为短期修复,您可以通过使用权限编辑文件并搜索以下行来禁用/etc/default/grub
它sudo
:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
删除splash
参数,使其看起来像这样:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
笔记:除 之外,您可能还有其他选项quite splash
。仅删除该splash
选项。
保存文件并退出编辑器。然后使用:
sudo update-grub
下次重新启动时,您会看到一个纯黑屏,而不是带有移动点的紫色启动画面。
长期解决方案
从终端使用:
$ systemctl list-units --all plymouth-quit-wait.service
UNIT LOAD ACTIVE SUB DESCRIPTION
plymouth-quit-wait.service loaded inactive dead Hold until boot process finishes up
LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
1 loaded units listed.
To show all installed unit files use 'systemctl list-unit-files'.
以上是正常输出。请比较一下您的输出并报告问题中的任何差异。
下一步是使用以下方法查找错误消息:
$ journalctl -b-1 | grep -i plymouth
