Ubuntu 18.04が過去1か月から頻繁にフリーズする
私はUbuntu 18.04を長い間使用していますが、先月からこの問題に直面するまで、フリーズの問題はありませんでした。しかし、Ubuntuを指差す前に、どちらが実際の問題かを確認したいと思います。
これらは私がこれまでに試したことです。 1.投稿で、マウスやキーボードがフリーズする理由は、USBポートにたくさんのほこりがある可能性があることです。そのため、CPUを2回クリーニングしました。初めて、私はほこりの粒子が本当にあったので、厚いウェブロールのようなものを作成することができました。 2回目は、掃除機の排気を使用して、SMPSとプロセッサの隅にあるすべてのダスト粒子を捨てました。 USBポートも高圧空気で掃除しました。
- マウスとキーボードを取り外し、再接続を試みましたが、それでも検出されません。
観察中にスタックオーバーフローのリンクをクリックしたところ、マウスとキーボードがフリーズしていましたが、約5秒後にフリーズせずにウェブサイトが読み込まれました。つまり、OS全体がUSBデバイスだけではないということです。
マウスとキーボードの両方が魔法のように同時に問題を解決することができないので、私はまだこれがUbuntuのせいかもしれないと思います。どちらも、ハードシステムリセット後しばらくの間は正常に動作します。だから私はシステムログを見ていました。以下はメッセージですが、何が問題だったかわかりません。

ポート番号4のUSBデバイスが切断されることを意味します。そのため、マウスまたはキーボードが機能しなくなります。システム自体については、お気づきのように問題なく、フリーズしていません。
この理由は、新しいカーネルがマウス/キーボードを適切にサポートしていないか、実際にはハードウェアの問題です。
古いカーネルで起動してみてください。この問題が発生する前にインストールされたもので、問題が存在するかどうかを確認します。存在する場合、それはおそらくマウス/キーボード、USBポート、またはコントローラーのハードウェアの問題です。
これを絞り込むには、接続されているUSB/HDMIデバイス（スピーカー、マイク、ヘッドホン、モニター、USBドライブ、マウス/キーボードなど）を制限し、予備のものがある場合は別のマウスとキーボードに変更してみてください。 USB/HDMIハードウェアとケーブルを取り外し、それらを1つずつ再接続するとともに、障害のあるポートが見つかるまで別のポートに接続し、新しいポートに交換します。
通知：
low-speed USB deviceは通常、マウスまたはキーボードを意味し、reset low-speed USB device最も可能性が高いのは、おそらくUSBに欠陥があり、場合によってはHDMIケーブルまたはデバイスに問題があるために、電気信号に欠陥があったことを意味します。
これは、一般的なマウスやキーボードの不良である可能性が高いことを意味します。これらを変更することで簡単に解決するか、マザーボード上のUSBポート/コントローラーの不良で、一般的ではないがマザーボードの交換が必要です。
幸運を祈ります
