>                 Key: GUACAMOLE-1036
>                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-1036
>             Project: Guacamole
>          Issue Type: Bug
>          Components: RDP
>    Affects Versions: 1.1.0
>         Environment: guacamole 1.1.0 on Manjaro with Docker 19.03.8-ce
>            Reporter: Jeffrey Lebowski
>            Priority: Minor

> I set up guacamole via docker and nginx as reverse proxy.
> VNC-connections work as expected, but RDP does not.
> The system I want to remote control is an Arch linux system running x11vnc and FreeRDP version 2.0.0 (git n/a).
> I would say the guacamole docker side is set up correctly because "everything VNC" and "everything SSH" to my Arch system works.
> The FreeRDP setup on the Arch system is this (started as a normal user, not root):
> {{[xx@arch]$ freerdp-shadow-cli -auth}}
> {{[13:12:17:144] [52077:52077] [INFO][com.freerdp.server.shadow.x11] - X11 Extensions: XFixes: 1 Xinerama: 1 XDamage: 0 XShm: 0}}

> The "funny" thing is that in the browser used to connect I can sometimes see a "screenshot" of my Arch desktop when trying the RDP connection but immediatly after that comes the guacamole error message aborting the connection.
> Another strange thing is that - only once - I got a "red screen" with "Welcome" written on it in the browser trying the RDP connection (but I did not the the desktop or anything else).
> I tried different RDP connections settings in guacamole - none of them works as expected.
