After launching windows 2016, Amazon EC2 instance,

I received ec2-18-221-95-56.us-east-2.compute.amazonaws.com.rdp file to connect to windows instance.

From my ubuntu laptop, Clicking the .rdp file, I receive this below message after providing password:

You requested an H264 GFX mode for server ec2-18-221-95-56.us-east-2.compute.amazonaws.com, but your libfreerdp does not support H264. Please check Color Depth Settings.

Ubuntu bionic laptop:

$ uname -a
Linux machine 4.15.0-34-generic #37-Ubuntu SMP Mon Aug 27 15:21:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Ran below commands, to resolve this problem(no luck):

sudo apt-add-repository ppa:remmina-ppa-team/remmina-next
sudo apt-get update
sudo apt-get install remmina remmina-plugin-rdp libfreerdp-plugins-standard

How to resolve this issue?

I haven't tried connecting to a Windows machine using a Linux OS using RDP, but I found something related to your issue that could help. It seems that by changing the color depth setting, should be enough to connect. I was reading this blog and it seems that this could be a solution.

Procedure for the workaround:

  • Click the little + in the upper-left corner of the window. It is a bit hard to see; the color scheme seems to be dark grey on grey.
  • From here, choose a different color depth setting
  • Click Save as Default, or enter other settings and click Save.

This was found by an user called Ian in that respective blog.

Update

In order to connect to your Windows VM, you need to right click on the instance, a choose connect. There you will find your public DNS, which you can use to connect to that machine. You will see the following dialog.

If you want your public IP, on your instance administration window, select the instance, and under description in the below menu, you will see it.

  • I could not find +, which window are you talking about? – overexchange Oct 28 '18 at 17:39
  • As far as I know, it is not in that dialog, it appears before you try to connect. It seems to be quite hard to find. – Alain Cruz Oct 28 '18 at 17:40
  • Yes I read that blog, that blog also asks for reinstalling remmina package.. I could not do that. Please provide the instructions for the same – overexchange Oct 28 '18 at 17:41
  • The other blog I found that could help you, is this one https://gitlab.com/Remmina/Remmina/issues/1584. It is quite hard to find information for this bug though. Not much on the Internet. Hope you can solve it. – Alain Cruz Oct 28 '18 at 17:43
  • I had been thru all this blogs.. how to launch remote desktop preference? – overexchange Oct 28 '18 at 17:57
  • It depends on the application you are using. Although, I think you are using Remnia, because of the command lines. So, in this [link](https://www.digitalcitizen.life/connecting-windows-remote-desktop-ubuntu) it seems that using Remnia you have to change the color depth when creating the connection. Please, let me know if it helps. – Alain Cruz Oct 28 '18 at 18:02
  • Installed RDP client remmina but struck in configuring RDP, because I created windows EC2 instance, but don't know the IP address of windows Ec2 to configure RDP – overexchange Oct 28 '18 at 18:24
  • Ohhh, now I understand. I edited my answer with the required information. Hope it helps. – Alain Cruz Oct 28 '18 at 18:35
  • Shall I copy the public dns name of aws as domain in rdp client? – overexchange Oct 28 '18 at 19:27
  • it is working now... public dns name is confusing me on aws..`ec2-18-221-95-56.us-east-2.compute.amazonaws.com` How do I interpret this? – overexchange Oct 28 '18 at 19:31
  • Yes, it is a bit confusing! Good thing it is working now :) – Alain Cruz Oct 28 '18 at 19:32
