I just tested this today and I was surprised to discover that RDP on plasma-wayland systems now works great, even on a plasma-nvidia-wayland host.
Also pleasantly surprised that the RDP client shows both connected displays on the host machine. In addition, RDP is stable even when connecting from a client over a wireless / cellular interface. It also works for a non-3389 port at the host.
Thank you KDE devs for the excellent work !
Here’s a sample setup, if anyone wants to try again :
Wayland Host
- Manjaro Linux 25.0 Zetar KDE (testing branch)
- Kernel 6.13.1
- Plasma 6.2.5
- NVIDIA 550.144
Wayland Client
- KRDC 24.12.2
- Manjaro Linux 25.0 Zetar KDE (testing branch)
- Kernel 6.13.1
- Plasma 6.2.5
- Intel UHD620
On a side note, the KRDP github page is missing KRDC as a working client, which probably should be added.
