Specify Xvnc session instead of Xorg for xrdp connection?

Issues & Assistance Unsupported Software (AUR & Other)
1

Maybe upstream is a better place to post, but i love you all, so i’m trying here. I’ve already done what’s in AUR wiki and some posts here:

Connecting to my computer via VPN / xrdp doesn’t work, i’m getting some connection issues thrown. When i switch from Xorg session to Xvnc, the desktop loads (YAY!). I’m wondering if there is a way i can avoid having to wait for the connection to fail before specifying Xvnc? I’m remoting from a 2014 Macbook Pro on Big Sur 11.6.8. Nothing in the mac rdp client seems to be labeled in a way that makes me think it will specify that.

Waiting for this connection to fail, then switching the session to Xvnc loads graphics settings.

Every time I am playing around with remote connection I have to specify the connection type from the Local machine RDP's application and could not configure the Remote machine to force a connection type to the Local machine. All I can do is setup a DEFAULT connection type on the remote machine.

In a way that makes sense as the remote machine doesn't know what the local machine wants and has installed unless the local machine specifies it to the remote.

Since RDP and VNC are not the same technology, when the remote receives a request that it cannot understand or that is not its default technology then it will not understand the request.

I am using Remmina on my local Garuda machines and if the remote linux (all Garudas of course!) is setup with both XRDP and XVNC I get a choice in a dropdown upon connection when I don't specifically force the connection type from the Remmina remote machine configuration. I can choose from 3 or 4, I have no idea how I installed all of those... but at least I don't need to "let the connection fail" before I change its type.

In that sense, is there a way to disable RDP and only enable VNC by default?
I have no idea on that but maybe it's a good place to start?

From the local machine, i'm using the microsoft remote desktop client for mac. I didn't see an option to use VNC, although it will connect and establish a VNC session. Since it's a work machine, i am kind of bound to the tools they provide.

I guess i'll have to live with it. SSH and SCP work for most things i need to do anyway (running DL projects on my GPU at home while i'm at work). Graphical sessions are just a convenience thing.

Thanks for your reply! :smiley:

Yeah but I understand how freakin useful they are. :slight_smile:

If there is a way for the remote linux machine to force a connection type to the local machine, I have not seen that yet, maybe I never looked deep enough, it was one way of fixing an issue I had in the past but found another way to do it in the end.

It’s linux afterall so pretty much anything is possible. :smiley:
