Ubuntu20.0.4でデフォルトフォントを日本語フォントに変更したい
Q&A
解決したいこと
Ubuntu20.0.4で以下コマンドにより日本語フォントをインストールしました。
sudo apt install fonts-noto-cjk fonts-noto-hinted fonts-noto-unhinted ttf-unifont
その後で、$ fc-match でデフォルトフォントを確認すると以下のように表示されます。
NotoSansCJK-Regular.ttc: "Noto Sans CJK JP" "Regular"が返ってくると予想しましたが、DejaVuSans.ttf: "DejaVu Sans" "Book" と返ってきました。"Noto Sans CJK JP"をデフォルトフォントにしたいのですが、何か処理が不足しているでしょうか。
宜しくお願いします。
$fc-match
DejaVuSans.ttf: "DejaVu Sans" "Book"
$fc-list でフォントの一覧を確認すると、NotoSansJavanese-Regular.ttf等が確認されます。
