Bug Description
I have an LG ultra-wide (2560x1080) monitor.
Sometimes when I plug it into my laptop, whose screen was working fine before I plugged it in, both screens go black but nothing else happens. I can still see the mouse cursor and move it between the two monitors (sometimes in the correct location configuration I've configured, sometimes not), but nothing is rendered on the screens.
Sometimes when I plug the monitor in, it comes on, but the resolution is wrong.
Sometimes it is actually recognized and configured correctly.
Frequently I have to unplug the monitor and plug it back in three times or more before it is recognized correctly.
I wish it just worked right the first time. :-/

I have Lenovo X1 Carbon laptop from 2014 with the following CPU:
Intel(R) Core(TM) i5-3317U CPU @ 1.70GHz
lspci reports GPU as
VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
I'm on Gentoo Linux with kernel 4.15.9-gentoo, xorg-server 1.19.5, libdrm 2.4.91 and mesa 18.0.0_rc4. I'm using modesetting driver without xf86-video-intel.
As my laptop has only mini displayport output, I'm trying to use DP-to-HDMI/VGA/DVI converter I got from AliExpress. Sometimes when I plug in the converter and enable the monitor with xrandr it works fine, but most of the time I see the output in xrandr, but when I enable it, monitor does not show anything.
I have this in dmesg:
[15:47] i915 0000:00:02.0: HDMI-A-1: EDID is invalid: dp_dual_ mode_detect] *ERROR* Unexpected DP dual mode adaptor ID 44 dp_dual_ mode_detect] *ERROR* Unexpected DP dual mode adaptor ID 44

I googled and found bug 92685 and tried kernel patch from there (https:/ /patchwork. freedesktop. org/patch/ 195306/), but it did not change anything for me.
Attaching i915_display_info and full dmesg, but without drm.debug=0xe yet.
