Created attachment 138094 [details] dmesg 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
