Ghost display in XFCE

Hi all! After moving to the ASUS VivoMini VC65 nettop and installing Arch I noticed strange behaviour in XFCE: in display settings dialog I see two identical monitors (see screenshot below). Display is connected via VGA. If I uncheck "Mirror Displays" then my connected display shows only #2 ghost monitor, the main workspace remains on the #1 monitor

My X11 have only one config file:

[viktor@desolve-nettop ~]$ cat /etc/X11/xorg.conf.d/20-intel.conf 
Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "TearFree"  "true"
EndSection

XRandR shows only one provider:

[viktor@desolve-nettop ~]$ xrandr --listproviders 
Providers: number : 1
Provider 0: id: 0x48 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 6 associated providers: 0 name:Intel

I don't know what's the cause of these bug and i want to eliminate any ghost displays. It worth to say that when I used this display with laptop all worked great and without any issues. My nettop have VGA, HDMI and DisplayPort ports.

Any help is greatly appreciated!

Re: Ghost display in XFCE

Strange.

What does just:

xrandr

...return?

And can you post back the contents of ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml.

Actually I have only one VGA, one HDMI and one DisplayPort sockets on my nettop. Can't understand why XFCE thinks that both eDP1 and DP2 are connected while my Belinea display connected only to the VGA adapter... I have no problems with this display and my previous Lenovo G570 laptop
