私のラップトップ（HP Elitebook 8570w）に問題があります。画面をオフにすると、スリープ/一時停止/休止状態に切り替わります（この機能の名前を選択できます）。ノートブックカバーを再び開き、セッションが再開されると、すべてが正常です。とは別にxfce4-panelが正しく描画されていません（完全に黒色であるか、以前に画面の対応する領域に描かれたもののアーティファクトがあります）。
ボタンをクリックすると、パネルは引き続きアクティブになりますが、描画または更新されなくなります。他のグラフィック要素はその上に「描画」パネルを使用するのが非常に困難になります。これを説明する最良の方法は、「グラフィックダメージ」または「加工物」です。しかし、これまでオンラインで私が経験しているのと同じ問題を説明している他の人を見たことはありません。
xfce4-panelプロセスを再起動してみましたが、同じ結果が再び発生しました。別のxfceプロセスを再起動しようとしましたが、xrefresh成功しませんでした。この問題を排除する唯一の方法は、ログアウトして再度ログインすることです。私はVMWare仮想マシンと他の多くを実行しており、一時停止/休止状態から戻るときに再起動できるようにメモリ状態を維持したいと思います。
完全に終了したり、セッションを失うことなくパネルを復元するために再起動できる他のプロセスはありますか？
一種の解決策であっても、この問題について洞察力を得てくださったら、本当にありがとうございます。ありがとうございます！
追加情報 -
メモ:
- Printscreenを使用してスクリーンショットを撮ると、描画呼び出しが一度通過し、パネルを更新して既存のアーティファクトが削除されますが（発生したアーティファクトのスクリーンショットも撮れません）、まだ行われていないことがわかりました。その後も引き続き更新してください。 「ウィンドウボタン」領域の上にマウスを置くと、ウィンドウのフルネームを含むツールヒントが開きます。このツールチップは、パネル領域を覆い、他のグラフィック要素が覆われるまでそのまま残ります。

この特定の問題に言及した投稿は、私が見た唯一の投稿です。また、Xubuntu 14.04 で XFCE パネルの破損の問題が発生し、ノートブックカバーを閉じて一時停止しました。ふたを開けると、パネルは常に損傷しています。通常黒です。デスクトップは大丈夫に見えますが、ファイルを開くと最大化などのさまざまなボタンがありません。
「ログアウト」メニューからラップトップを一時停止しても問題はありません。すべてが完璧に戻ってきました。
問題の最後に、メモリを節約するために無効にしたデスクトップの「コンポジション」オプションを再度有効にするというアイデアが浮上しました。合成を有効にすると損傷の問題が解決されました。単純な。
私のラップトップもHPです（モデルは異なりますが）。問題がHPに限定されているのかはわかりません。
これが誰かに役立つことを願っています。
