Unable to access ubuntu's graphical interface.

Question

I read the document entitled "Install and configure xrdp to use Remote Desktop with Ubuntu". I think the xfce interface used in the document is too simple and I want to use Gnome. But when I install Gnome and try to use the rdp link to ubuntu, only a blue background is displayed, nothing can be seen, and no operation can be performed. How should I deal with this situation?

Hello Alice nonce

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

Based on the details shared, you're running into an issue with the Remote Desktop Protocol (RDP) client not properly displaying the Gnome desktop environment.
One thing you can try is adjusting the settings in the RDP client to optimize performance for the Gnome desktop. In the Display tab, try setting the color depth to High Color (15 bit) and in the Experience tab, set the connection speed to Modem (56 kbps).

Additionally, you can check the logs in /var/log on your Ubuntu VM for indications as to why the service may not be responding.

You can also monitor the syslog during a remote desktop connection attempt to view any errors.

Also, make sure that the Gnome shell is installed, Install xRDP Gnome Extension.

sudo apt-get update
sudo apt-get install gnome-shell
sudo apt-get install chrome-gnome-shell

Install Gnome Tweaks and change the default desktop environment:

sudo apt-get install gnome-tweaks

sudo nano /etc/lightdm/lightdm.conf

In the file, add the following line under the [SeatDefaults] section and restaret xrdp service.

user-session=gnome

sudo service xrdp restart

Enable the xRDP Gnome Extension:

Open Gnome Tweaks -> Go to Extensions ->Search for xRDP->Enable the xRDP extension

Log out and log back in, or restart the computer.

Try connecting to the Ubuntu machine using xRDP and see if Gnome is now working as expected.

Hope this helps.
