Blank Window is Shown When Starting the App Over an RDP Connection on Linux

Problem

When starting Oxygen XML Developer or its installer on Linux, a blank window is displayed when started over an RDP connection.

Cause

Oxygen XML Developer and its installer are Java Swing apps that require a 24 bit color depth from the X server.

Solution

  1. If you are using xrdp, find the /etc/xrdp/xrdp.ini file.
  2. Uncomment the xserverbpp=24 line.
  3. Save your files and close all the apps (the subsequent step will terminate your remote session so you could lose your progress if you do not save your files first).
  4. Restart the xrdp service:
    sudo systemctl restart xrdp.service
Note: Alternatively, you can try setting max_bpp=24 in the same /etc/xrdp/xrdp.ini file.
