Hyper-v上のUbuntuの画面サイズ変更

Last updated at Posted at 2022-06-19

Hyper-vにUbuntuを入れた時、設定画面で画面サイズの変更ができなかったので、画面サイズの変更方法をメモとして残します。

やり方

/etc/default/grubにあるGRUB_CMDLINE_LINUX_DEFAULTが下のように書かれていますが、

変更前
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

この行にvideo=hyperv_fb:1920x1080を追加します。(1920×1080ドットの場合)

変更後
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1080"

その後、grubを下のコマンドでアップデートします。

sudo update-grub

アップデート後に、Ubuntuを再起動します。
