[Software] How to install krdp on ubuntu 25.10?

[sweinst]

Hi
I'm trying to connect remotely to my headless server using RDP. The server is running ubuntu 25.10

I'm currently using xrdp and it's working finr

I've read that it's now possible using krdp and soo it should allow me to use wayland instead of X11

I've installed the kde-fulll, kubuntu-restricted-extra (for the codecs) and thge krdp packages

It doesn't work:

• the remote desktop configuration module doesn't appear int the kde control panel (when uing a xrdp/X11 session)
• when I run (in a remote ssh session) krdpserver -u user -p test, I get the error message

krdpserver -u user -p test
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb, wayland, vnc, linuxfb, vkkhrdisplay, offscreen, minimal, wayland-egl, eglfs, minimalegl.

libxcb-cursor0 is already installed

Does someone know how to install krdp?

sweinst Not sure if you found a solution to this but it seems that you are running into this problem because you are running this command over the ssh. Due to this its unable to find the wayland or xcb Qt platform plugin as the session will be tty when you connect using ssh. Try running the same command from within the desktop terminal and make sure to configure the certificate\keys before hand

(when uing a xrdp/X11 session)

you must use wayland for krdp to work ,it doesn't work in a X11 session

side note: either stick with xrdp which is most reliable ,or consider
RustDesk (Wayland-friendly, works headless) or NoMachine (very solid performance)
