Cinnamonを含むDebian 10(Buster):ハードウェアレンダリングなし

Cinnamonを含むDebian 10(Buster):ハードウェアレンダリングなし

デスクトップ環境としてDebian BusterとCinnamonをインストールしました。ログイン後、シナモンはソフトウェアレンダリングモードで実行中であることを通知する警告をデスクトップに表示し、トラブルシューティングの目的にのみお勧めします。ログには.xsession-errors同じ内容が記載されています(下記参照)。私はシナモンがウェイランドのリーダーシップの下で運営されていると仮定します。

システムに専用グラフィックカードがありません。これインテルI7 9700K CPU代わりに、プロセッサグラフィックが使用されます。

Cinnamonをハードウェアアクセラレーションで実行するにはどうすればよいですか?

システム

CPU:       Intel I7 9700K (Coffee Lake)
Mainboard: MSI Z390 A-Pro (latest BIOS)
SSD:       Samsung SSD 970 Evo Plus at the board's M.2 connector
OS:        Debian 10 (Buster)

答え1

別のマザーボードを試した後、ついに問題が解決しました。

必要な唯一の変更は、Debian BusterのデフォルトのLinuxカーネル(4.19.x)をDebian Busterがバックポートした最新のカーネル(5.3.x)に更新することです。

アップデート後、ソフトウェアレンダリング警告メッセージは消え、追加の処置は不要です。
