Multiple monitor success on Raspberry Pi 3B+

[asm32]

Howto on my web page at http://multi-seat.com/raspbian-dual-monitors/ using DisplayLink DL-125 usb to vga adapter for second monitor. Does anyone have the later DL-165 based adapter to test this? It would be nice to have the full 1920 x 1080 resolution on the secondary adapter.

How does one determine if an adapter is a DL-165 ?

I have no idea what mine are, are generic unbranded, but I thought I'd plug one in again as multiple desktop monitors is on my list of things to try again. I'm guessing mine aren't as plugged into a Dell monitor which supports HDMI and VGA fbset shows -

Code: Select all

mode "1440x900-60"
    # D: 106.508 MHz, H: 55.939 kHz, V: 59.892 Hz
    geometry 1440 900 1440 900 16

It seems I already had libxinerama-dev installed, Raspbian Stretch Full non-NOOBS install, and your guide worked a treat whereas I'd failed before. So many thanks for that.

I initially had an inch wide band of black on the VGA's right. Might be worth suggesting doing an 'auto-adjust' on the monitor before jumping to the conclusion something has gone wrong.

Also a minor typo on your linked page; "now to create an /etc/X11/cxorg.conf". There's an extraneous 'c' in there.
