Xinerama 同时具备硬件加速功能

有没有办法可以启用 Xinerama 并继续使用硬件加速？我在 2 个 GPU 上有三个显示器。我已启用 Xinerama，但现在所有硬件加速都消失了。这导致游戏帧率不佳，并且 Compiz 无法正常工作。如果这不可能，有没有办法在不使用 Xinerama 的情况下在 X 屏幕之间移动应用程序？这是我的 xorg.conf，由 NVIDIA X Server Settings 生成：

答案1

尝试包括

option "RenderAccel"  "true"

在您的"Device"部分中。

答案2

这似乎是不可能的，因为 Xinerama 模拟单个虚拟显示器。由于这个虚拟显示器完全是软件，所以不可能有硬件加速。

我通过使用内置 DVI 分配器的显卡解决了这个问题。操作系统只能看到单个大显示器。

调整 compiz 后最大化窗口工作，请参阅将显示器一分为二。
