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ので、デスクトップ環境がログイン直後に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ていました)。LXDE と MATE の両方をインストールしていますが、両方で同様のクラッシュが発生しています。2 つの DE は異なるウィンドウ マネージャー (Openbox と marco) を使用しているため、X サーバーに問題があるのではないかと考えています。
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コンソール tty に切り替えるために etc. を使用することもできません。数分後、lightdm ログイン画面に戻ります。
次のようなエラー（関連があると思われる）が見つかりました~/.cache/lxsession/LXDE/run.log:

何が原因なのか、誰か分かるでしょうか?memtesterコメントで提案されているように実行してみましたが、RAM に問題は見つかりませんでした。コンソール端末では、システムは完全に安定しているようです。
問題は、Arch ARM の不良パッケージが最後のアップデート中にシステムを壊しただけである可能性があります。どのパッケージが壊れている可能性があるか、誰か考えはありますか? (もしあれば、ロールバックしてみます)
答え1
上記のコメントに投稿されたとおり:
Xorg ログ ファイルにはglamoreglクラッシュが発生していることが示されており、ハードウェア アクセラレーションの問題が指摘されています。
一時的な回避策：GLXを無効にしてXを起動するこの郵便受け例:
startx -- :2 vt2 -extension GLX
私が疑問に思っていることの 1 つは、GPU 用の特定の独自仕様/オープン ソース ドライバーがあるかどうかです (お使いのモデルの場合は Mali グラフィックス T764 であるはずだと理解しています)。この郵便受け示唆しxf86-video-armsoc-rockchipていますveyron-libgl。おそらく、私も見てみるでしょう開発者向け
