帮助理解日志

  • 772

刚刚安装了 Ubuntu 20.04。系统一直冻结，我必须使用电源按钮将其关闭并重新打开。有人可以帮我分析这个日志文件，如果我不知道有什么问题吗？

    您的 /etc/fstab 不正确。

    它显示了 /swapfile 的三个条目...

    /swapfile                                 none            swap    sw              0       0
/swapfile none swap sw 0 0
/swapfile none swap sw 0 0

    使用应用程序编辑您的 /etc/fstab terminal，使用命令sudo -H gedit /etc/fstab，删除前两个 /swapfile 行，保留第三个 /swapfile 行，保存编辑的文件，然后重新启动。

    额外说明：不要使用badblocks或e2fsck损坏 SSD/nvme。

    更新#1：

    BIOS

    联想 V14-ADA

    您有版本 E8CN25WW，日期为 2020 年 10 月 13 日。有更新的 BIOS，版本 E8CN27WW，日期为 2021 年 2 月 5 日，可在此处下载。

    注意：确认我有适合您的型号的正确网页#。

    注意：在更新 BIOS 之前做好备份。

    交换

    你的 2G /swapfile 太小了。我们将它增加到4G...

    注意rm：和命令的错误使用dd会导致数据丢失。建议复制/粘贴。

    在terminal...

    sudo swapoff -a           # turn off swap
sudo rm -i /swapfile      # remove old /swapfile

sudo dd if=/dev/zero of=/swapfile bs=1M count=4096

sudo chmod 600 /swapfile  # set proper file protections
sudo mkswap /swapfile     # init /swapfile
sudo swapon /swapfile     # turn on swap
free -h                   # confirm 12G RAM and 4G swap

    编辑 /etc/fstab，使用sudo -H gedit /etc/fstab或sudo pico /etc/fstab。

    在 /etc/fstab 中确认此 /swapfile 行...并确认没有其他“交换”行...在此行中使用空格...确认 NO TABS...

    /swapfile  none  swap  sw  0  0

    reboot                    # reboot and verify operation

    更新#2：

    这台计算机在 Ubuntu 和 Fedora 34 上死机。现在切换回 Windows。
