Native RDP on Ubuntu 22.04 not working

rated 0 times [ 1] [ 0] / answers: 1 / hits: 10034 / 1 Year ago, mon, january 23, 2023, 5:58:09

Here is my experience. I installed 22.04 the installed Chrome which started to use something called "keyring" which completely messed the RDP feature.

So I reninstalled VM quickly and tried to use RDP without adding any other software.

I ran apt upgrade

enabled Settings - Sharing

tried to connect from W11 into Hyper-V Ubuntu 22.04.01

this is what I got:

Try RDP from Windows again - this time it asks for password and the RDP window opens but with another error inside it:

systemctl --user status gnome-remote-desktop.service - shows a lot of errors (you need to read them side-by-side):

The error, that mstsc here shows is very generic. However, what seems to be clear is the following:

The client is the one here disconnecting from the server

The graphics pipeline ([MS-RDPEGFX]) is used.

No frame is shown by mstsc.

There is a known bug in mstsc, that selecting a Color depth other than "32-bit", then using the graphics pipeline (which according to your logs successfully initialized (see the "CapsAdvertise" message)) fails, although the client accepted using the graphics pipeline.

The Color depth setting is only for ancient servers (WinXP era) and the graphics pipeline only uses 32-bit as colour format: https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-rdpegfx/80afb419-0cd5-49f8-8256-f77cc1787ec9

In the connecting screen of mstsc, go to the "Display" tab and under "Colors", select "Highest Quality (32 bit)".
I think that this might be the issue here.
