I am trying to get KRdp up and running on my Arch install with a Nvidia GPU running Plasma 6.1.1 in Wayland.
I have the service set to start automatically and made sure to log into a session before trying to connect. The desktop is at the lock screen. Could that be causing the problem?
I am connecting using the Microsoft RDP client built into Windows 10. A black screen appears and then I get a message that the remote desktop services session has ended. I pulled everything from the systemd journal when I try to connect and krdpserver shows a segfault and a stack trace is provided. Any ideas?
