Hello there!
After connecting and enabling the 3rd monitor in D-Sub, the one with DP becames
black. Most of the time I use 2 displays with (DVI-I and DP) without any
problem. The desired layout is the following, however I even tried to use HDMI
instead of DVI-I:
___ __ __
|DVI||DP||DS|
2 1 3
__ __ ____
|DS||DP||HDMI|
2 1 3
None of the options are working, however it's fine on Windows using the lastest
- official beta - Crimson Edition 15.7.1.
The motherboard had an ASMedia ASM1445 DVI/HDMI bridge, so I couldn't use these
outputs at the same time.
CPU: AMD A8-6500
GPU: AMD Radeon HD8570 (ATOMBIOSBK-AMD VER015.031.000.000.000000,
02/17/13,02:36:07)
MOBO: ASUS F2A85M-PRO (BIOS 6601)
OS: Arch Linux 4.13 AMD64
xf86-video-ati 1:18.0.0-1
xorg-server 1.19.6+13+gd0d1a694f-1
The logs/outputs were saved at 4.13, however it's not working with both the
up-to-date Arch (4.15) and Xubuntu 18.04 beta.
Thank you
