Any hints at all on this?

*Subject:* Config to be able to switch X output between 2 video cards
via ARandR/xrandr
Hi,
My hardware setup is 2 video cards (1 integrated Intel, 1 discrete
Nvidia). Intel is connected to a monitor via HDMI, Nvidia is connected
to the same monitor via DVI. There's also internal monitor hard-wired to
Intel via eDP-1 output (you can see it in attached files).
I want to have 2 available outputs in ARandR so I can e.g. switch X
output from (Intel->HDMI) to (Nvidia->DVI) and then manually choose
input port (DVI/HDMI) on the hardware monitor.
I'm starting X with just startx - disabled display manager to eliminate
it as a factor.
Here's my lspci output:
[username@arch ~]$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500
(rev 09)
02:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX
1060] (rev a1)
After reading various Xorg manuals I came up with attached Xorg config.
Some options are adopted from nvidia-xconfig output. I have 2 entries
for monitors, because I want it to run at 144Hz when signal comes from
Nvidia and at 60Hz when signal comes from Intel (Intel card can't output
144Hz).
This config behaves as follows:
1. On boot video output (with text tty login) goes to Intel->HDMI
2. I log in, run startx, HDMI screen goes black (but there's a HDMI
signal - monitor does not power down)
3. After switching input port to DVI on the monitor I see my usual
Openbox session
The problem is that ARandR shows only DVI-D-0 as selectable output.
Attached are xrandr outputs for various queries. Apparently outputs to
Intel are "active" (marked with "*"), but I get only blank screen on them.
What should be fixed with this config (or something else) to be able to
switch X output between (Intel->HDMI) and (Nvidia->DVI)?
