If you have both arch linux and manjaro installed, post logs from an arch linux boot.
Incase you only have manjaro, ask on their forums.
Please post the contents of Xorg.log and the output of dmesg.
dmesg: https://drive.google.com/file/d/1YwsAJW … sp=sharing
and

]]>Do you see something interesting in the Xorg log file or the journal?
No
]]>What about "amdgpu.dc=0" on the kernel command line? Did you try that as well? You only mention "amdgpu.dc=1" which is the default setting.
I have already tried amdgpu.dc=0. Same results. The 2nd monitor is disconnected according xrandr.
Thanks

]]>When I boot I get the 2 screens with the grub menu on both screens.
As soon as I press enter or select whatever, one of the screen gets disconnected and I can't reactivate it.
$ cat /etc/default/grub | grep -ve ^#

GRUB_TIMEOUT_STYLE='menu'

I have tried 4.14.90, 4.19.13, 4.20.0: it's the same thing.
I can't reactivate the second screen:

Something in the boot process deactivates the 2nd screen. It happens immediately after the grub menu.
I have tried: amdgpu.dc=1 amdgpu.dpm=0 as command line parameters without success.
Any suggestion on what to do?
Thanks
