Xorg.log file when KO

Hi,

I finally tried the 4.12.2 kernel, and in my case it does not fully work :(

I can see a working console, but:
- only on my first monitor (DVI), black screen on all other monitors
- no x11 on all monitors (I can see a brief display of xfce4 but immediately
turns black and no more display, even if I return to the console.)

I think I'm facing 2 different issues. One is about detecting my second monitor
(a 4K LG 31MU97 plugged on DP-0 (this display is maybe a bit slow to probe))
The log shows a lot of error concerning this monitor...

But I do not see anything on my third output too (HDMI, this is an av receiver,
with a full HD tv). No error at all for this one, even the resolution is probed
correctly by xorg. I was expecting at least a console on this one.

The kernel log shows an EDID error for the LG monitor...
