Linux Sender - Multiple monitors - HP Thin Client / Windows Receiver

HP Recommended



we're struggling a bit with Linux Senders using a headless configuration to work across multiple monitors.


We have 2 x 1920x1200 monitors connected to either Windows 10 or HP T630 Thin Clients.

We've created an EDID with an Eizo CG319X and followed the instructions in the Zcentral Admin Guide PDF, here's our basic xorg.conf:


Section "Device"

        Identifier  "Videocard0"
        Driver      "nvidia"
        BusID       "PCI:134:0:0"
        VendorName  "NVIDIA Corporation"
        Option      "AllowEmptyInitialConfiguration" "true"

Option "ConnectedMonitor" "DFP-0,DFP-1"

Option "CustomEDID" "DFP-0:/etc/X11/Eizo_CH319X_EDID.bin; DFP-1:/etc/X11/Eizo_CH319X_EDID.bin"


Section "Screen"
        Identifier  "foobar"

Option "TwinView" "true"

Option "MetaModes" "DFP-0: 4096x2160 +0+0, DFP-1: 4096x2160 +4096+0; DFP-0: 4096x2160 +0+0, DFP-1: 1920x1080 +4096+0; DFP-0: 4096x2160 +0+0, DFP-1:NULL; DFP-0: 2560x1440 +0+0, DFP-1: 2560x1440 +2560+0; DFP-0: 2560x1440 +0+0, DFP-1: 1920x1080 +2560+0; DFP-0: 2560x1440 +0+0, DFP-1:NULL; DFP-0: 1920x1200 +0+0, DFP-1: 1920x1200 +1920+0; DFP-0: 1920x1200 +0+0, DFP-1:NULL; DFP-0: 1920x1080 +0+0, DFP-1: 1920x1080 +1920+0; DFP-0: 1920x1080 +0+0, DFP-1:NULL; DFP-0: 1680x1050 +0+0, DFP-1: 1680x1050 +1680+0; DFP-0: 1680x1050 +0+0, DFP-1:NULL; DFP-0: 1600x1200 +0+0, DFP-1: 1600x1200 +1200+0; DFP-0: 1600x1200 +0+0, DFP-1:NULL; DFP-0: 1400x1050 +0+0, DFP-1: 1400x1050 +1400+0; DFP-0: 1400x1050 +0+0, DFP-1:NULL; DFP-0: 1280x1024 +0+0, DFP-1: 1280x1024 +1280+0; DFP-0: 1280x1024 +0+0, DFP-1:NULL"

SubSection "Display"

        Depth 24




Works fine with a single monitor, but over a pair of monitors, we get the following output:



Just a single 4k X Screen, which doesn't scale over 2 monitors.


Any support would be greatly appreciated.

We have dual 27" monitors working without issue.  But they are actual monitors connected on the Sender side.  Have you tried adding dummy dongles on the sender side?
