我使用Ubuntu18.04LTS,使用Win10双引导。每当我启动系统,就需要3分钟。同样在登录屏幕之前,这个东西出现了,我正在附加一个屏幕截图。

这个标志代表什么,如果这是高启动时间的原因,如何摆脱它?

这是磁盘分区:

If you have any advice, I would be happy to hear! Thanks! 发布于 2019-08-12 11:58:37
禁用fstrim使用:
rm /var/lib/systemd/timers/stamp-fstrim.timer
systemctl stop fstrim.service fstrim.timer
systemctl disable fstrim.service fstrim.timer
systemctl mask fstrim.service fstrim.timer这将从您的启动删除300万,但没有修复问题。你还得把它找出来。例如:您有交换分区吗?如果是这样的话,将其移除并将一个交换文件添加到/etc/fstab,并查看这是否是问题所在。undefined
journalctl -u fstrim将展示一份关于fstrim的报告。
请注意,如果您这样做,您应该手动启动fstrim,并且可以用
sudo fstrim -v /https://askubuntu.com/questions/1165128
