Created attachment 170737 [details] Krdp server log SUMMARY When i try to connect with remmina, i enter in a "Attempting to connect" loop. I can't connect to my server (which is on the same PC for testing purpose). The log seems to highlight an issue with client icompatibility not supporting H.264. But on GitLab, Remmina is in the list of working clients. STEPS TO REPRODUCE 1. Launch the server via KCM or CLI 2. Launch Reminna 3. Establish the connection with the server OBSERVED RESULT "Attemting to connect" loop screen on Remmina. EXPECTED RESULT Remote server screen. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Linux 40 KDE Plasma Version: 6.1.0 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION Platform: Wayland Graphics Card: NVidia GeForce GTX 1650 Graphics processor: NV167 Nvidia driver version: 555.42.02
The warning about H264 is because Fedora does not have hardware encoding by default, unless you install third party Mesa drivers from RPM Fusion with those built in. It should still work in software mode though. Do you have open H264 drivers installed? Or anything that supports H264 software mode? The logs mention error with the graphics driver, so this might be Nvidia related issue... Can you try running this with environment variable like this from terminal: KPIPEWIRE_FORCE_ENCODER=libx264_baseline krdpserver -u test -p test You can also try KPIPEWIRE_FORCE_ENCODER=libx264 krdpserver -u test -p test Please report if either those work or not! Thanks!

Thank you for your help, I have the following RPMs installed: - intel-media-drivers from RPM Fusion - x264-libs from RPM Fusion - openh264 I tried your two command lines but unfortunately it didn't work. I have attached the new logs from krdpserver and vainfo output. If you have any other suggestions, I am willing to try.
The relevant line here is "org.kde.krdp: Client does not support H.264 in YUV420 mode!" which indicates your client does not handle H264 decoding. Is this using Reminna from Fedora packages?
Yes, Remmina come from Fedora packages : remmina-1.4.33-1.fc40.x86_64 I found this bug https://bugzilla.redhat.com/show_bug.cgi?id=2242462 but it seems to be fixed. When I try with Remote Desktop from Windows 11, krdpserver crashes with segmentation fault. I will create another bug report for this.
If you have the dependencies installed, you might need to set some option in Reminna so it enabled h264 decoding. Ultimately there's little we can do on the server end, there isn't even a clear way of telling the client "this does not work".
