fglrx 支持 4 个头的 ATI FirePro 2460

我正在运行 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux，带有 FirePro 2460。这是带有 4 个头的单 GPU。我可以让 3 个显示器正常工作，每个显示器都运行在不同的 xserver DISPLAY 名称下，:0.0、:0.1、:0.2。当我添加第四个显示器时，我在 Xorg.0.log 中看到以下错误

[4.063] (EE) fglrx(3): 由于硬件限制，显示基础设施失败
[4.063] (EE) fglrx(3): PreInit 失败

这是提出这个问题的正确地方吗？我已附上 xorg.conf 和 Xorg.0.log，希望有人能给我提供答案或提出问题的正确地方。

谢谢，Donald Kayser

答案1

万一其他人发现这个帖子，我有来自 AMD 的答案。

“您无法连接 4 个不同的 DVI 显示器。您只能通过显示端口连接它们。所有显示端口显示器可以共享一个时钟，而每个 DVI 显示器都需要自己的时钟，因此可能的 DVI/HDMI 连接数量是有限的。”

仅供参考。我能够让两对相同的显示器工作。每台显示器的分辨率都不同。
