在一個大的視訊緩衝區中設定兩個視訊輸出

無需使用 Xinerama 軟體即可支援兩個監視器。這表示 Sun XVR-100繪圖加速器將建 立一個較寬 ( 或較高 ) 的視訊緩衝區,且使用 DVI 連接埠在兩個螢幕中顯示。

要在一個視訊緩衝區中設定兩個視訊輸出,請執行下列操作:

1.啟用兩個視訊輸出,並共用一個視訊緩衝區。請鍵入下列指令

host% fbconfig -dev pfb0 -doublewide enable

對於上下排列的顯示器,請使用 -doublehigh選項 ( 而並排的顯示器請使用 -doublewide選項 )。兩個顯示器的解析度必須相同。

使用 -outputs swapped 選項顛倒兩個視訊輸出彼此相對的位置。預設值是 direct。兩個顯示器的解析度必須相同。

使用 -offset選項根據指定值調整指定視訊輸出的位置。

-offset xval yval

只在 -doublewide-doublehigh模式下執行。對於 -doublewide xval 用於定位最右側視訊輸出。負數表示向左偏移 ( 與左側視訊輸出重疊 )。 對於 -doublehighyval用於定位底部視訊輸出。負數表示向上偏移 ( 與頂 部視訊輸出重疊 )。預設值是 [0, 0]

2.設定所需的螢幕解析度。請鍵入下列指令:

host% fbconfig -dev pfb0 - res 1280x1024x76

注意 DVI 視訊連接埠支援高於 1280 x 1024 的螢幕解析度 ( 請參閱1-2以取得 DVI 連接埠支援的顯示器解析度 )

以下為 1280 x 1024 螢幕解析度在兩個螢幕上複製一個串流的完整重疊範例:

host% fbconfig -dev pfb0 -offset -12800 -doublewide enable
