我正在尝试按照Akshit 的终端指南将我的外部硬盘驱动器设置为在启动时自动挂载。

我最初在 `/etc/fastab' 中使用了 PARTUUID 而不是 UUID：

UUID=191486e0-6049-46aa-973c-425d317b629a /mnt/nas exfat uid=1000,gid=1000,umask=0022,auto,rw 0 0

当我运行时，这给了我一个错误，findmnt --verify --verbose我重新检查blkid并注意到我一直在使用分区 ID：

/dev/sdb1: LABEL="My Book" UUID="20C9-C659" TYPE="exfat" PTTYPE="atari" PARTLABEL="My Book" PARTUUID="191486e0-6049-46aa-973c-425d317b629a"

所以我在 fstab 中添加了实际的 UUID，但现在我不确定我是否应该使用它或者我是否应该使用 PARTUUID，以及为什么我的 UUID 比我见过的其他示例短得多（特别是当“保证 UUID 是唯一的。据我所知，在宇宙的生命周期内不会发生碰撞”）。

从睡眠模式返回时，我的笔记本电脑的 LCD 只显示雪花（如没有信号的模拟电视）。除非我重新启动它，否则没有任何变化，没有显示输出。我在作者用来输出引导加载程序配置并添加要恢复的设备的地方发现了这个问题。sudo nano / etc / default / grub他没有具体说明 UUID 正在使用哪个设备，我想这是必须恢复的 GPU，但它可能是屏幕。我将尝试他们两个，看看哪一个可以工作，但我如何获得他们的 UUID？

最近安装多个操作系统后，我遇到了启动错误。我注意到很长的启动时间，看着启动加载代码过去了，显然卡在了一个需要 90 秒的启动作业上，然后才最终退出显示 [Timed] 和 [delay] 的失败，很难阅读整行跑出屏幕继续启动。它在引导期间几乎所有机器上的操作系统都有延迟。

我跑了journalctl -p err，发现以下内容：

我意识到最后安装的操作系统是 2020 年 1 月 3 日的 Debian 10。我还记得安装程序要求我确认我定义的分区/并将/home被格式化，但它也添加swap到了列表中。

我启动到 Debian 操作系统并运行 blkid 并查看了 Debian fstab 文件，如下所示定义了两个交换 - 不是手动的，安装程序出现了一些错误。

不知何故 Fedoraswap和共享/dev/sda5 swap在 Debian 的 fstab 中？所有系统启动，仅在交换超时时都会延迟 90 秒。自从 Ubuntu 16.04.6 接近 ESM 以来，我正在玩一些发行版。一旦我决定保留和删除哪些操作系统，我可能仍然会遇到问题。任何技术帮助将不胜感激和感谢。

我的问题是，如果我在我的带有 radeon hd graphics × 2 的 pavillon G7 AMD A6-4400m apu 上睡觉或休眠，屏幕将永远不会再次打开，背光灯打开但 lcd 保持黑色。我试图禁用挂起，只关闭显示器并锁定会话，但这没有帮助。我尝试了 Ubuntu MATE、Xubuntu、Lubuntu、Linux Mint，它在所有这些上都可以做到，但在 Windows 7 上从来没有。这台机器上的显示器没有 BIOS 设置。我试过 ctrl + alt + F1 和 alt + ctrl + Del 也没有用。请帮忙

我在问如何更改uuid，/boot/grub/grub.cfg以便 grub 可以在指定的分区上加载操作系统。

我有两个磁盘：

  • SSD /dev/sda1 与 uuid d7f0cf11-3edf-4859-b65a-3b5bc60ea7b9
  • 硬盘 /dev/sdb1 与 uuid 47d9205b-00a8-40e5-88d6-e8b9571799a7

两个磁盘都包含相同的内容（一个 Ubuntu 根目录）但不同的分区 uuid sda1，sdb1因为clonezilla

问题是/boot/grub/grub.cfg，它是自动生成的，包含：

           if [ x$feature_platform_search_hint = xy ]; then
              search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1  47d9205b-00a8-40e5-88d6-e8b9571799a7
            else
              search --no-floppy --fs-uuid --set=root 47d9205b-00a8-40e5-88d6-e8b9571799a7
            fi
            echo    'Loading Linux 4.4.0-146-generic ...'
            linux   /boot/vmlinuz-4.4.0-146-generic root=UUID=47d9205b-00a8-40e5-88d6-e8b9571799a7 ro  quiet splash $vt_handoff

表明 grub 选择 Ubuntu rootsdb1而不是sda1，而我希望它选择sda1.

我尝试直接替换所有47d9205b-00a8-40e5-88d6-e8b9571799a7，d7f0cf11-3edf-4859-b65a-3b5bc60ea7b9然后运行update-grub，但随后一切都恢复了。

那么还有其他更好的解决方案吗？/boot/grub/grub.cfg实际上是自动生成的。如果我分离了sdb1，grub 将无法启动，因为它找不到sdb1.

谢谢

我已经克隆了我的 SSD 并使用 Live 发行版重新启动以更改相应的 UUID。

不幸的是，当我跑步时

tune2fs -U {some_UUID} /dev/sda5

我得到错误

tune2fs: Bad magic number ....
/dev/sda5 contains a LVM2_member

两个副本都会发生这种情况..所以我无法更改 UUID。如果我尝试预订，由于 UUID 重复，系统无法启动。

在这种情况下如何更改 UUID？

我在 SSD 上安装了 Ubuntu 18.04.2 LTS，我还安装了 HDD 以获取数据。但是当我这样做时，它的 UUID 包含随机的数字和字母集，例如 /mnt/9d79a504-bf86-4a1f-99e4-927b9e20df6e，即使我标记了它并给我的磁盘起了一个简单的名称 - 存储，我仍然无法像终端中的 cd /mnt/Storage 那样导航到它，我也尝试给它一个别名，但它失败了。那么有人可以帮助我吗？谢谢！

我检查了下面的这个链接，看起来很相似，但是，我不得不问这个问题。 如何在 nautilus 中为其他驱动器和分区提供简短、有意义的名称？ 如何更改驱动器的名称？

我通过使用 Live DVD 得到了这个输出。我将initramfs在此之后添加提示输出。

运行 Ubuntu 18.04，我从交换分区更改为交换文件。

swapon -s（摘要）并免费显示具有新大小的交换文件。/etc/fstab 已更改，交换文件的权限已更改，并且交换分区已删除。当有更新（apt-get 更新和升级）时，我收到此错误：

Setting up amd64-microcode (3.20180524.1~ubuntu0.18.04.2) ...

W: initramfs-tools configuration sets RESUME=UUID=c5a2c6f4-b67c-4d95-bc23-8333ed6c0f11
W: but no matching swap device is available.

那里列出的 UUID 用于旧的交换分区。我不认为交换文件有 UUID，但我不确定。其他一切似乎都很好。我应该如何进行故障排除和修复？
