我无法将EDID显示器连接到四个有效显示设备中的三个。
最初从物理传递从rhel 7.2 KVM到rhel 6.6 guest,然后在同一硬件上继续使用裸机rhel 6.6。
裸金属与客人的行为相同。
Xorg.log声称DFP-0,DFP-1,DFP-2,DFP-3为有效的显示设备。
EDID监视器只能连接到DFP-0,但不能连接到其他3个显示设备。
我需要连接两个EDID监视器,因此我需要两个能够连接的显示设备。
我正在使用352.79驱动程序。

I am unable to connect EDID monitor to three out of four valid display devices. Originally started with physical pass through from rhel 7.2 KVM to rhel 6.6 guest, then continued with bare metal rhel 6.6 on the same hardware. The bare metal behaves same as the guest. Xorg.log claims DFP-0, DFP-1, DFP-2, DFP-3 as valid display devices. EDID monitor can connect only to DFP-0 but not to the other 3 display devices. I need two EDID monitors connected, hence I need two display devices capable of connecting. I am using 352.79 driver.
