I am using Odoo 11 community version on CentOS 7 64 bit machine. I followed the instructions to set this up. It was working fine for while. Basic setup would be...a desktop with a screen, mouse, keyboard and barcode scanner for employee. POSbox with a screen, printer and a cash drawer for client.
I updated some configs and the colorful, pretty GUI on customer display is gone. the customer display shows css-less text...As if you were looking at some receipt. So when I scan an item using the barcode scanner or even choose the item on the POS display, the customer display is updated but the GUI isn't pretty as the default one that comes with it.
From the admin menu, i tied to edit the POS ( point of sale -> configuration -> edit). In that edit form, there is a section to customize the customer display. In this section, you can choose the theme, color etc. that looks nice. When I choose the theme and save the settings, it does not reflect on the customer display.
I tried to reboot the server several times but that did not help. Also not sure how to debug the PosBox client display. if anyone can point me in the right direction, it would help me debug the issue.
JAN 18 UPDATE:
I noticed that if I open the customer display on the POS host, it shows the GUI perfectly fine. If I use the POSbox connected display to view the gui, it does not work. Any ideas?
