Xは HDMIケーブルでつないだTV画面にでない。 （Xアプリはセキュリテイ上動かさないのが安全）
でも 換気扇をコントロールするarmなopenbsdにとって HDMIポートそのものが邪魔くさい。
他のPCから ssh で入れさえすればいい。
そうすれば

fake history
歴史が 本当はどうであったかの判断は 歴史学者に任せるべきで政治に任せてはいけない。従って A国 B国で 認識の差があるのなら A国 B国の歴史学者でまず見当すべきものである。
過去の遺物、文献、録音、写真、ビデオなどを 解析する能力は そういう訓練を受けたことのない政治家にはない （昔の文字が読めるか、真偽の度合いはどうか等）。
一流のフランス料理は 政治家の能力を遥かに超え、プロのコックにまかすべきものだ。
そうしないと fake history ができあがる（alike fake news）。
以下の 正史＝fake history も参照のこと
