Hello!
For all my remote desktop client needs, I’ve been using Apache Guacamole (sorry, I apparently cant add links), which supports connections to SSH, VNC, and RDP servers through the browser. I noticed in the KRDP Readme it doesn’t specifically say if it works or not, but it looks technically it should be supported.
In the “Known Issues and Limitations” section, the readme says “Only the NLA security type of RDP is supported,” a setting that can be set by Guacamole
and “Only the Graphics Pipeline extension of the RDP protocol is
implemented for video streaming,” which has been available in Guacamole for years (github com/apache/guacamole-server/commit/da80163e24dbf728f5c2e1245c23ded5f629917e)
However, when trying to connect, I get the following error:
krdpserver[6958]: org.kde.krdp: Client does not support graphics pipeline which is required

Is this an actual incompatibility with Guacamole (and if so, what is missing), or is this a bug?
