This may be a duplicate of #3021, or at least related to it.

Can you paste xrdp.log following a connection?

matt335672 avatar Apr 27 '24 08:04 matt335672

Scrub the last comment - #3021 is using the krdc client.

I still need that log though.

matt335672 avatar Apr 27 '24 08:04 matt335672

Thanks.

Looking at the sources, there's not a lot of logging for client resizes on V0.9.x. It's a bit better on v0.10.x

A couple of things to check:-

  1. If you really are using a Microsoft client, be aware than mstsc.exe doesn't support this functionality. The client from the Windows App store does (although it has its share of other problems).
  2. Make sure drdynvc=true is set in the [Channels] section of xrdp.ini.
  3. Failing all of that, can you set LogLevel=DEBUG in /etc/xrdp/xrdp.ini? That will slow things up a bit. Then try a resize and see if you get any useful logs in /var/log/xrdp.log.

you didn't tell me that I had to try resizing. This is the log:

Thanks - that's exactly what I needed.

You're getting these messages on a resize request. They show the request coming in from the client for a resize:-

[20240429-11:26:46] [DEBUG] dynamic_monitor_data: msg_type 2 msg_length 56
[20240429-11:26:46] [DEBUG]   MonitorLayoutSize 40 NumMonitor 1

Then this happens when the VNC server successfully resizes:-

[20240429-11:26:45] [DEBUG] VNC Sending SetDesktopSize
. . .
20240429-11:26:45] [DEBUG] VNC server successfully resized

However, you're also seeing this happen:-

[20240429-11:26:46] [DEBUG] dynamic_monitor_data: msg_type 2 msg_length 56
[20240429-11:26:46] [DEBUG]   MonitorLayoutSize 40 NumMonitor 1
[20240429-11:26:46] [DEBUG] Skipping RFB_ENC_RAW encoding
[20240429-11:26:46] [DEBUG] VNC server does not support resizing
[20240429-11:26:46] [DEBUG] Resizing client to server 1276x1010

What's happening here is although the VNC server supports resizing, xrdp is not remembering this from previously. It sends a resize request, and instead of an acknowledgement it gets another screen update. So it assumes the VNC server doesn't support resizing and just asks the client to resize instead. So this is definitely a bug.

The good news is this is fixed in v0.10.x which is in beta at the moment. At the moment we don't have plans for other fixes to v0.9.x apart from security fixes. I'll mark this a a v0.9.x problem so if this changes we can pick it up.

This is possibly happening when the VNC server is busy and refreshes are happening. It's possible if the resizes are done when the server is quiet there won't be a problem.

Are there any beta builds to try? Or must be compiled?

superbonaci avatar Apr 30 '24 11:04 superbonaci

We don't provide binary packages here - that's up to the distros.

Fedora uses Koji as its build system. When a beta is available it will show up here:-

https://koji.fedoraproject.org/koji/packageinfo?packageID=9026

matt335672 avatar May 01 '24 08:05 matt335672

@matt335672 is not possible to distribute xrdp stable/beta as flatpak/snap? that would be great.

superbonaci avatar May 01 '24 11:05 superbonaci

Maybe, but it's not an area we'd want to get into at present.

matt335672 avatar May 01 '24 13:05 matt335672

I've uninstalled the xrdp package from fedora 40 and manually compiled and installed latest commit from this project following the wiki, but the issue is now work because the connection closes immediately during resize. RDP client: Error code 0x200d.

Use the v0.10 beta:-

https://github.com/neutrinolabs/xrdp/releases/tag/v0.10.0-beta.3

and:-

https://github.com/neutrinolabs/xorgxrdp/releases/tag/v0.10.1

matt335672 avatar May 07 '24 11:05 matt335672

What's the difference between the two?

superbonaci avatar May 07 '24 19:05 superbonaci

One's been through user-acceptance-testing at one of our enterprise users, and the other hasn't.

matt335672 avatar May 08 '24 09:05 matt335672

I mean what is the difference between xrdp and xorgrdg (not git commit versus zip), and can or must I have both of them installed at the same time?

superbonaci avatar May 08 '24 15:05 superbonaci

I see you're using the VNC backend, so you don't need xorgxrdp - my mistake.

xorgxrdp is a module for Xorg which provides an alternative to Xvnc. It's not enabled by default for Fedora/RHEL/etc.

matt335672 avatar May 09 '24 09:05 matt335672

It works with gnome, but doesn't with kde or plasma

superbonaci avatar Jun 25 '24 09:06 superbonaci

If you're on Fedora, and you're running xrdp v0.10.x by now (packages are available I believe) feel free to open a new issue. We're not aware of any problems in this area with v0.10.x yet.

matt335672 avatar Jun 26 '24 08:06 matt335672

I think it's the whole wayland/kde/plasma thing still not ready. Fedora is meant to be used with gnome which works.
