Waylandネイティブのキオスクスナップを作成しようとしたときのエラー

Ubuntu 16.04を実行しています。 From https://tutorials.ubuntu.com/tutorial/wayland-kiosk# Waylandネイティブのキオスクスナップを作成

https://tutorials.ubuntu.com/tutorial/wayland-kiosk#4 で、次のエラーが発生します。

user @ machine：〜$ miral-app -kiosk -launcher 'glmark2-waylandはエラーを生成します：eglGetDisplay（）はエラーで失敗しました：0x3000

以下のターミナル出力。

user @ machine：〜$ miral-appは、オレンジ色のMir On Xウィンドウを生成しますが、その後、黒いターミナルウィンドウが表示されます。

user @ machine：〜$ miral-app -kioskは、Xウィンドウに黒いMirを生成し、無応答のファイル、編集などを行います。

user @ machine：〜$ miral-app -kiosk -launcherは、すぐに閉じる黒いウィンドウを生成します。

このチュートリアルを進める方法について何か提案はありますか？

user@machine:~$ miral-app -kiosk -launcher 'glmark2-wayland'

あなたが見ているもののいくつかを説明できます。次のメッセージは異常であり（Mirには致命的ではありません）、グラフィックハードウェアが私がアクセスしたものと異なることを示唆しています。

[2019-07-30 11:57:00.334962] < -warning- > Wayland: Failed to bind Wayland EGL display.

Mirが作業を続けている間、glmark2-waylandが同じことに遭遇すると失敗する可能性があります。

Waylandスタックの多くのものが16.04と18.04の間で改善されたため、Ubuntu 18.04でより良い結果が見られるでしょう。

他の呪文で見られる問題（miral-appおよびmiral-app -kiosk）は、16.04のWaylandに対するサポートが不十分なためです。これらはチュートリアルとは関係がないため、ここで説明する価値はありません。
