ログイン時にX11がクラッシュする（Arch ARM）

私はChromebook C201（ARM）でArch Linuxを使用しています。最近システムをアップグレードしたため、ログイン直後にデスクトップ環境がクラッシュするようです（アップグレード前は正常に動作しました）。 LXDEとMATEがインストールされていますが、どちらも同様の競合が発生します。両方のDEは異なるウィンドウマネージャ（Openboxとmarco）を使用しているため、Xサーバーに問題があると思われます。

システムがクラッシュすると、画面がフリーズし、デスクトップが完全にロックされます。マウスやキーボードの入力に応答がなく、CTL-ALT-F2などを使用してコンソールttyに切り替えることはできません。数分後、lightdmログイン画面にリダイレクトされました。

次のエラーが見つかりました（関連しているようです）~/.cache/lxsession/LXDE/run.log。

この問題の原因が何であるかを知っている人はいますか？私はこれを実行しましたがmemtester（コメントで提案されているように）、メモリに問題はありませんでした。コンソール端末では、システムは非常に安定しているようです。

問題は、単に最後の更新中にシステムを破損したArch ARMの無効なパッケージである可能性があります。どのパッケージが破損しているかを知っている人はいますか？ （そうであればロールバックしてみます）
