マイコンピュータはグラフィックの問題なしにDebian Wheezy(3.2カーネル)から起動します。 sid(3.10カーネル)にアップデートした後、画面が黒く変わり(つまり、ディスプレイがしばらく点滅してからスリープモードに切り替わります)、カーネルがradeonフレームバッファ(起動せずに起動する場合)オプションを設定しようとするとオフになりますnomodeset
。ロードされたモジュールを渡しますmodprobe radeon modeset=1
。)その後、カーネル(3.10と3.11)、Mesa、xorgドライバを直接コンパイルして同じ結果を得ました。

答え1
これはカーネルエラーです。このカーネルバージョンでは、radeon KMSドライバの1行を調整してカーネルを再構築する必要があります。しかし、最新のカーネルバージョンでは修正されたため、これらのほとんどは議論の余地があります。
