I got this problem few weeks ago, likely after updating something. When I boot grub shows on both monitors but choosing Arch makes second monitor go black. I have to restore it with these commands, and it works until next restart (disabling/enabling 2nd monitor in settings also work, sleep doesn't break it):
xrandr --output DisplayPort-0 --off --output DVI-I-1 --off --output DVI-D-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output HDMI-A-0 --off
xrandr --output DisplayPort-0 --off --output DVI-I-1 --mode 1920x1080 --pos 1920x0 --rotate normal --output DVI-D-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output HDMI-A-0 --offGraphics: Card: Advanced Micro Devices [AMD/ATI] Tonga PRO [Radeon R9 285/380]
Display Server: x11 (X.Org 1.19.3) driver: amdgpu
Resolution: 1920x1080@60.00hz, 1920x1080@60.00hz
OpenGL: renderer: Gallium 0.4 on AMD TONGA (DRM 3.15.0 / 4.12.6-1-ARCH, LLVM 4.0.1)
version: 4.5 Mesa 17.1.6About week before this happened I switched from broken DisplayPort cable to HDMI <> DVI-I cable, which worked until this problem came in *some* update (i've done many updates since then, not sure of date).
This happens in terminal and in X, I think it's driver issue of some sort. I can't see anything in dmesg.

Did you try the suggestion in "DisplayPort stays black on multimonitor mode" troubleshooting section at arch wiki ATI page?

I don't use DisplayPort. Before I changed the cable I tried that workaround since i thought problem was in driver, but it didn't do anything (and moving cable a bit restored signal sometimes so it was broken)
OK the monitor that keeps black is DVI-D-0, it is detected as monitor 1 but it's my second monitor.
1st monitor: DVI-D-0
2nd monito: DVI-I-1
All works in grub -> select linux and second monitor goes black, then boot messages show -> disable / enable monitor in XFCE settings or xrandr and it works normally, powersave or sleep doesn't break it again.
in dmesg is

I have almost exactly same setup as this guy https://forum.manjaro.org/t/amd-dual-mo … f-dvi/7318, outputs are same and graphics card is TONGA, but R9 285 instead of 380X
"i thing that comes to my mind is that, maybe it could be because one of the DVI cables is digital and one is mixed digital and analoque. and the driver/hardware cant handle this setup or something.
I think this was the issue. I since have replaced the DVI cable on the ASUS monitor with an HDMI cable and I am happy to say that all is now well. I now have two working monitors in the correct orientation10! Thanks to everyone who gave me tips and pointers along the way I very much appreciate it and I look forward to enjoying Manjaro. Bye for now!"
