2016年7月20日の更新後、16.04にランチャーとパネルが表示されなくなりました

昨日定期的なシステムアップデートをインストールして再起動すると、突然Launcherとメニューバーが表示されなくなり、同様のタイトルのスレッドの下で回答を探してみましたが、私が試したことは何も役に立たないようです。 Compizで統一を無効にし、再度有効にしました。私はLinuxが初めてで、まだあまり詳しくありません。私は学ぼうとしていますが、他のスレッドで提案されたすべてのことを試してみましたが、運がありませんでした。

私が今何でもできる唯一の方法は、端末にunity --debugと入力すると、ランチャーとメニューバーを（一時的に）再表示できることです。

Compiz configディレクトリを削除すると、@zerkms提案。ありがとうございました！

特に、私は使用しました

mv ~/.config/compiz-1 ~/Desktop

うまくいかなかった場合にデスクトップに移動するには、そのままでは削除されず、犯人でない場合は元に戻すことができます。ディレクトリを移動した後、再起動後にすべてが正常に戻りました。

答えてくれてありがとう、まだn00bですが、私が学ぶ小さなことはすべて役立ちます！

私も同じ問題を抱えていましたが、compiz-1ディレクトリを削除しても問題は解決しませんでした。これは機能しますが、完全ではありません：

dconf reset -f /org/compiz/
setsid compiz --replace
