最近、SSDを大容量のSSDに交換しました。クローンジラ古いディスクを新しいディスクにクローンしました。その後、GPartedライブ既存のパーティションのサイズを変更し、スワップ パーティションをディスクの末尾に移動します。また、Ubuntu 16.04 から 18.04 にアップデートしました。
上記の手順を正常に完了した後、起動時間が大幅に長くなった同様のスレッドをいくつか見つけ (下記にリンク)、そこで提案されていることを試してみました。ただし、起動時間はディスク変更前まで短縮されませんでした。
これが私のオリジナルです/etc/fstab
:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation
UUID=e15b2ef7-c32d-46f5-a3a8-4bdc60285b4e / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=3a0c2581-52f2-4c92-9c4a-09d3f0258c05 none swap sw 0 0
/dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0 /mnt/usb-Generic_USB_Flash_Disk-0:0 auto nosuid,nodev,nofail,x-gvfs-show 0 0
私はすでにパーティションUUID
のを置き換えました。swap
blkidさんコマンド出力:
/dev/sda1: UUID="e15b2ef7-c32d-46f5-a3a8-4bdc60285b4e" TYPE="ext4" PARTUUID="000d7e8b-01"
/dev/sda5: LABEL="swap" UUID="839f9d78-77b2-491d-808d-8cd551a9eeef" TYPE="swap" PARTUUID="000d7e8b-05"
/dev/disk/by-id/usb-..
また、これは GParted Live を起動した USB スティックだと信じているので、コメント アウトしました。なぜそれがまだそこに定義されているのかはわかりません。

のシステム分析コマンドは次のように伝えます:
Startup finished in 36.037s (kernel) + 10.847s (userspace) = 46.885s
graphical.target reached after 10.835s in userspace
起動時間を改善するにはどうすればいいでしょうか?

「履歴書」ファイルがあるのではないかと思う
/etc/initramfs-tools/conf.d/resume
これはもう見つからないUUIDを指しています。そのファイルを修正してスワップパーティションの正しいUUIDを指し示し、以下を実行します。
sudo update-initramfs -u
バグレポートへのリンクのコメント#16と#17を参照してください。
あなたのケースとバグレポートのケースには違いがあります。
- あなたの場合はスワップパーティションを使用しています
- バグレポートの場合、スワップ ファイルが使用されています (したがって、指すべきスワップ パーティションは存在しません)。
