以下の記事で書いた内容を別のPC（CF-N10）でやったので、ログ残しておきます。

ハイバーネーションテスト
taka@cfn10:~$ systemctl hibernate
Call to Hibernate failed: Invalid argument
taka@cfn10:~$ う、エラー発生。あと、sudoつけなかったら、パスワード入力ウィンドウがポップアップしました。やっぱり、権限必要ですよね。
→ grubの設定のUUID間違えていました。修正して、もう一度再起動します。
→更にNG、今度は、swap領域が少ないと出ました。
なぜかというと、fstab で、swapをもう一つ設定していることが原因でした。
fstabには、こう書かれています。
/dev/disk/by-uuid/8ee09f92-db5b-403c-b056-4896fbe0ef12 / ext4 defaults 0 1
/swap.img none swap sw 0 0
//192.168.11.3/share /media/ls2t cifs guest,uid=1000,vers=2.0 0 0
swapfile none swap sw 0 0
この内、/swap.img none swap sw 0 0
が、問題で、/swap.imgが4GBのファイルでした。
fstabを修正します。
/swap.img を削除して、あと、/swapfileの行、swapfileだったのですが、絶対パスにしました。

ふう、ちゃんと休止し、また、復帰しました。
