Accessing Ubuntu 24 using the "Remote Login" feature

[raffaeler]

I tested Ubuntu24 new "Remote Login" feature successfully using Windows RDP client. Basically, there are two sets of credentials.

• with the first credential set (which can be specified in the "Remote Login" dialog, the Windows RDP client accesses Ubuntu remote login screen.
• The second set of credentials matches the Ubuntu user, as if you were trying to access from the main (physical) PC

I tried to access Ubuntu 24 using mRemoteNG, but I cannot access it. I tried the following:

• specifying the first credential set
• setting the two sets using the same username/password
• specifying the second credential set

It didn't work in any case.

Expected Behavior

I expect to be able to log in as the Windows RDP client did

Current Behavior

I cannot login at all.

Steps to Reproduce (for bugs)

1. Install a plain Ubuntu 24 VM, accessible from Windows on the network (locally is ok)
2. Enable the Remote Login feature in Ubuntu (it's new in Ubuntu 24)
3. Try to access Ubuntu 24 using mRemoteNG

Please note that Remote Login is specifically designed to allow accessing remotely via RDP without logging in locally first.
Accessing the shared desktop is already possible in Ubuntu 22 and 23 but not if the local pc desktop is locked / logged off.

Your Environment

• Version used: 1.77.3 (nighly build: 1784)
• Operating System and version (e.g. Windows 10 1709 x64): Windows 10 (but this is not relevant)

I would appreciate any feedback/suggestion on how to successfully access Ubuntu 24 using the new Remote Login feature.
Thanks

I'm seeing the same thing here.

Using the built in Windows RDP client, login is fine. Using mRemote, the connection fails and mRemote displays the following error:

----------
WarningMsg

RDP error!
Error Code: 5
Error Description: Language.strRdpErrorCode3

Getting the same output as EmeraldFlame.. :\
I also can confirm that using Microsoft's Remote Desktop Connection is working fine so it's not a server error.

Same here

Just wanted to add myself to the folks encountering this issue. Connecting through desktop sharing works fine, but Remote Login fails exactly as EmeraldFlame reports. Connecting through the Windows 11 RDP client works as expected.

I have done some testing and can confirm that it's a similar issue on Fedora, latest version (41 Workstation Edition).

It is possible to make it work if you change the resolution to either fullscreen or a fixed resolution.
It's also possible to start in fullscreen, then minimize it to a tab, right-click the tab, and select SmartSize (though the image will appear blurry).

Personally, I just set the resolution to be slightly smaller than the actual window, so I get some gray borders. 😊

What known limitation of .net 6 - they cant do better for windforms, its a bit better on .net 8 but still need adjustments

[Kvarkas]

after investigation is seems RDP v12 not working properly, need to fix that, however you could still connect using v11:

hint: I am not linux guy, so just simply installed latest ubuntu 24.04 on VMware, and used this manual: https://www.digitalocean.com/community/tutorials/how-to-enable-remote-desktop-protocol-using-xrdp-on-ubuntu-22-04

if you want me to test other ways - let me know what to do with ubuntu to allow rdp (how you doing it)

@robertpopa22 what's the best / fastest way to get the binaries for this fork or for dev? Are they pre-compiled?

He is using ai, temporary I block him, as I am on vocation with limited access to internet and sinking in auto messages from his ai

Thank you @Kvarkas, anything we can try to overcome this issue? workarounds?
