I have created a unique test box with XRDP. It is a docker container built off of Alpine, using Xorg-server, openbox as my window manager, and no desktop manager. .xinitrc calls my application as necessary. I can start the container and RDP into it with Microsoft RDP client just fine. No issues.
I try to login with Guacamole and it immediately freezes. The screen partially or fully renders, it appears to capture some amount of mouse movement, but then is completely unresponsive. Disconnecting and reconnecting will show a different screen, showing some communication has happened. Guacamole can access Windows systems just fine. I have also gotten it to work with XRDP before on Linux desktops just fine Can someone explain why Guacamole will not work with XRDP/Openbox here, but Windows will?
