    我的深度,刚开始15.4的时候,开机只要20秒左右,现在要将近一分钟,忍不可忍.比Windows7的半分钟慢多了

    那就来分析下问题在哪里,到底是哪个环节慢了

    先在终端执行如下命令
    1. systemd-analyze
    Copy the Code
    输出如下:
    1. ch@ai:~$ systemd-analyze
    2. Startup finished in 7.825s (kernel) + 38.210s (userspace) = 46.036s
    Copy the Code
    可以看到,开机花了46秒,最慢就慢在用户空间这块,内核启动实际上只花了7.8秒.

    那么用户空间究竟干了啥导致deepin开机慢呢?执行下这个命令
    1. systemd-analyze blame
    Copy the Code
    输出如下:
    1.          23.005s apt-daily.service
    2.          12.479s plymouth-quit-wait.service
    3.           7.729s ModemManager.service
    4.           7.714s loadcpufreq.service
    5.           7.572s dev-sda5.device
    6.           4.668s systemd-journal-flush.service
    7.           4.149s systemd-logind.service
    8.           3.417s systemd-rfkill.service
    9.           3.385s pppd-dns.service
    10.           3.330s alsa-restore.service
    11.           3.297s avahi-daemon.service
    12.           3.289s networking.service
    13.           2.741s lightdm.service
    14.           2.548s NetworkManager.service
    15.           2.544s lastore-daemon.service
    16.           1.884s lvm2-monitor.service
    Copy the Code
    好家伙,就plymouth-quit-wait.service 和 apt-daily.service 这俩家伙最坑爹.也可以
    1. sudo systemd-analyze plot > boot.svg
    Copy the Code
    导出分析结果为图片.


    plymouth-quit-wait.service 这家伙是干啥的呢,这家伙就是开机动画.会不会是这里的问题

    关闭 主题试试.
    然后再禁用下服务:
    1. sudo systemctl mask plymouth-quit-wait.service
    Copy the Code
    关闭这个服务没事吧?没事的,只是开机会变丑一点.

    那apt-daily.service又是干啥的呢?
    我们来看下:
    1. systemctl status apt-daily.service
    2. ● apt-daily.service - Daily apt activities
    3.    Loaded: loaded (/lib/systemd/system/apt-daily.service; static; vendor preset: enabled)
    4.    Active: inactive (dead) since Tue 2017-12-26 19:21:27 CST; 36min ago
    5.      Docs: man:apt(8)
    6.   Process: 503 ExecStart=/usr/lib/apt/apt.systemd.daily (code=exited, status=0/SUCCESS)
    7. Main PID: 503 (code=exited, status=0/SUCCESS)

    9. Warning: Journal has been rotated since unit was started. Log output is incomplete or unavailable.
    Copy the Code
    看看这个服务都干了啥
    1. $ cat /usr/lib/apt/apt.systemd.daily
    Copy the Code
    发现干的都是些apt包管理的事情,这个也好办,大不了我需要的时候手动清理和升级就好了
    执行下面的命令
    1. systemctl disable apt-daily.service
    Copy the Code
    .
    打完收工,再重启下看看
    1. $ systemd-analyze
    2. Startup finished in 7.495s (kernel) + 18.579s (userspace) = 26.074s
    Copy the Code


    现在开机没有动画效果了,丑了一点,但是开机速度提高了20多秒

    但是,问题在于,deepin从输入密码登录到壁纸显示到桌边图标都出来这段时间特别长,有半分钟吧,从而导致了上述的优化感觉不出明显的变化,都耗在登录的阶段了.显示开机26秒,实际上可用还是需要一分钟还多的时间.
    ********************************
    你的systemd-analyze blame输出和我的不一定相同,我只是提供一种思路.

    公司里下班不关机要罚款的

    我是日常用，公司还管那么多干啥，到桌前按个开关再处理下整东西倒水什么的杂事，这点时间完全没影响，再说deepin我觉得开机已经很快了，曾经用ubuntu的时候感觉开机更慢
