Xrdp not working since plasma 6

General system Newbie
1

Hello! My system has been working well with plasma 6, but I have noticed that I can no longer connect to it via RDP. I simply get a black screen. I also noticed that xrdp was upgraded at the same time as plasma 6 to xrdp 0.10.0_beta.1-1. Since xrdp is now in beta, maybe I should wait a while before doing too much more troubleshooting, as this remote connection is not mission critical. I’m really just wondering if anyone else has seen this problem.

I can see that my SDDM greeter now offers the choice of starting a wayland session or an x11 session. Could it be that the remote session is being started as wayland? (which I don’t think would work with xrdp.) I think the “waitforx” timeout seen in the log below suggests this could be the case.

Please advise.

Welcome to the forum!

Sounds like Wayland to me.

Have you tried it in an Xorg session?

I did. After the black screen times out, the blue screen appears and with Xorg as the default session type. It fails with the same message
xrdp
xrdp1
.

The release of xorgxrdp 0.10.0-5 fixed this problem for me. The issues is explained by the people at Neutriolabs labs here

Isn’t it in the name Xrdp is for X AFAIK there is KRDP for Wayland when you are on KDE Plasma.

The client PC in this case happens to be a Windows machine. I use Bitvise to start ssh shell sessions and/or RDP sessions. I looks like the problem I was having was only with the previous version or xorgxrdp. It had nothing to do with X11 or Wayland, thankfully, because I am not familiar with the inner workings of either.

I didn’t know why you were using xrdp, but I thought I would at least mention it and yes xorgxrdp breaks sometimes.
