This document provides techniques to reduce the bandwidth between network zero-client devices and host PC. As each of the techniques have some impact on user experience, they are only recommended as a temporary solution or as a troubleshooting isolation technique.
Method #1: Show only window border while dragging
This technique toggles the Window Manager to show the window border (and not update window contents) when dragging windows around the screen.
Note: This only impacts Linux Desktop and Cloud Desktop sessions, not VDI sessions.
- Open terminal as root user on host PC
- Move to the autostart directory by typing following command:
- Create a new file on the command line:
- Copy and paste the following content exactly into the terminal:
- Press "CTRL+D" to close and save the file
- Reboot the system

Method #2: Change color depth to 16bpp and/or reduce display resolution
In the Control Center > Display Management screen
- Change the color depth for all zero client devices from 32bpp to 16bpp. For most users the difference with 16bpp is barely noticeable.
(Note: Do not change color depth for onboard host station).
- Although the impact is much more visible if you don't require a full 1080p screen, lower the monitor resolution (e.g., to 720p) and achieve a considerable bandwidth reduction.
