关于双屏显示的奇葩问题

tyronewoo

Yosemite DP6
硬件配置如下：E3-1230V3
                         技嘉B85N 凤凰
                         8G内存
                         微星 HD7850 hawk 1G
                         双显示器 DELL U2412M（mini dp）+DELL P2714H(dvi）
引导工具clover 2830+GPT的纯UEFI引导，显卡非DSDT驱动，通过clover fake0X68181002驱动，然后问题就出现了。
1.启用纯UEFI引导的时候双屏无法显示，也无法进入桌面，mini dp接口有输出信号，dvi接口无输出或者花屏。
2.启用传统引导的时候可以双屏进入桌面，但是无法上网，网卡能驱动，不能通过DHCP获取地址，手动指定IP地址也无法上网。
是否必须修改fb来支持双屏，望赐教！

想要完美驱动还是得DSDT+FB 才行，Clover 自带的修复不靠谱。

貌似是如此，另外一台同样配置但是显卡是GTX760的机器双屏就毫无问题，GTX760貌似是免驱卡，双屏使用非常方便。

原来我的GTX460 双屏都是修改的DSDT里边的NVCAP代码成功多屏输出

Apple就这样   你必须改fb   
n卡的幸运草自动识别并注入了 所以才可以双瓶
    Apple就这样设置的   不服？

目前学习修改FB中。redsock信息如下：

显卡接口如图所示

目前修改了FB为DP+DP+HDMI+DVI,但是双屏显示仍然无法输出信号，DP接口无法输出信号，现在想要实现DP+DVI接口输出，请问下FB要如何修改才能生效？

修改如下：

00040000040300000001010112040401  DP

00040000040300000001020122050302  DP

04000000140200000001030010000206  DVI

00080000040200000001040011020103  HDMI

显卡接口从PCI槽开始依次为DVI HDMI DP DP,目前修改结果双屏依然无法输出，DP接口无任何显示，请教下我需要如何修改FB才能达到DP+DVI双输出？
