システムが何かを処理し続けているため、ノートパソコンが熱くなります。

システムが何かを処理し続けているため、ノートパソコンが熱くなります。

Ubuntuを実行するとシステムが熱くなり、主な処理はありません。また、同じコンピュータでWindows 10を実行していますが、Windowsで実行すると熱くならないため、ハードウェアの問題を排除できます。最良の推測はドライバの問題です。これは、AMD RadeonでNvidia GPUをエミュレートするためにOcelotを使用するためにシステムを操作した後に問題が発生しましたが、すべての変更をキャンセルして問題が解決しないためです。

それとも、私のシステムがどのグラフィックカードドライバを使用しているかを確認する方法はありますか?
