Description fell 2024-06-21 10:45:58 UTC

SUMMARY
I wanted to test out the new RDP feature in Plasma 6.1, but it seems like it does not work. When attempting to connect with the Windows 10 RDP client (see details below) it fails with "An internal error has occurred". Unfortunately it does not give me any other information.

The physical monitor of the remote machine was turned off when testing, this may or may not be related.

STEPS TO REPRODUCE
1. Set up a system with Plasma 6.1
2. Enable the RDP server in the system settings
3. (May be optional) Turn off or disconnect the monitor
4. Attempt to connect from a Windows machine
5. Accept the warning about the self-signed certificate

OBSERVED RESULT
The RDP client initially connects. It warns about a self signed certificate. After confirmation, it displays a black window matching the screen dimensions and an error message reading "An internal error has occurred".

EXPECTED RESULT
The RDP client initially connects. It warns about a self signed certificate. After confirmation, it displays an interactive window showing the screen of the remote machine.

Comment 2 Akseli Lahtinen 2024-06-24 07:28:38 UTC

Can you install debug symbols for krdpserver and try again to see if the segfault happens? https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Backtraces

Also I can't connect to my system either, but I do not get a crash with KRDP. So there is connection issue at the very least.

Hello,

Don't know if useful to mention it also, but same issue on Arch also.
I'm full intel on a laptop.
