This simple tutorial shows how to enable RDP remote desktop for extended screen in Ubuntu 22.04, Ubuntu 24.04, and Ubuntu 25.04 with default GNOME desktop.<\/p>\n

Since Ubuntu 22.04, the default GNOME desktop has built-in RDP support. The function has feature to share screen in ‘extend’ mode.<\/p>\n

In this mode, Ubuntu won’t mirror the primary display, but create virtual extended screens for remote access.<\/p>\n

Each remote connection is limited to its own virtual screen.<\/b> You can drag and drop any app windows to that screen, allowing remote users to see and\/or manipulate, while keeping sensitive data un-accessible in primary screen.<\/p>\n

Or, you can use remote client PC\/laptop’s monitor wirelessly to setup multiple screens for the Ubuntu machine. Though, operating in the virtual external monitors will be a bit laggy.<\/p>\n

<\/p>\n

In the screenshot below, there are 2 machines connected to my Ubuntu PC via RDP remote desktop protocol. So, there are 2 virtual displays created. Each remote machine can access Ubuntu through its own virtual screen. While, user in front of Ubuntu can operate all the 3 screens (if 2 other monitors are sitting nearby).<\/p>\n

\"\"<\/a><\/p>\n

Step 1: Enable RDP remote desktop<\/h3>\n

Firstly, open Settings<\/b> and navigate to ‘Sharing<\/b>‘. Then, click open ‘remote desktop’ configuration dialog. Enable that function and leave ‘Enable legacy vnc protocol’ disabled. Also, toggle remote control and setup password according to your need.<\/p>\n

For Ubuntu 24.04, go to Settings -> System -> Remote Desktop, then enable “Desktop Sharing” and configure other options as you want.<\/b><\/p>\n

\"\"<\/a><\/p>\n

Step 2: Setting Screen Sharing Mode<\/h3>\n

Then, search for and install Dconf Editor<\/b> (if you don’t have it) from Ubuntu Software.<\/p>\n

\"\"<\/a><\/p>\n

Then, launch ‘Dconf Editor’ and navigate to \/org\/gnome\/desktop\/remote-desktop\/rdp\/screen-share-mode<\/b>. Finally, turn off ‘Use default value’ and set Custom value to extend<\/b>.<\/p>\n

\"\"<\/a><\/p>\n

For those who are familiar with Linux command, this step can be done by opening terminal (Ctrl+Alt+T) and running a single command:<\/p>\n

gsettings set org.gnome.desktop.remote-desktop.rdp screen-share-mode 'extend'<\/pre>\n
Finally, you can share your IP address, user and password you set in step 1 to your friends for accessing remotely.<\/p>\n
In addition:<\/h3>\n
To access outside of home\/local network, you need to setup either DMZ host or IP port forwarding (3389 in the case). The setting varies depends on your router, so I won’t cover it here.<\/p>\n
Also, if you don’t plan to sit in front of the Ubuntu machine all the time, install the “Allow Locked Remote Desktop<\/b>” could be useful to prevent connection lost due to screen lock.<\/p>\n
To do so, install and open “Extension Manager” from Ubuntu Software. Then, use it to search and install the extension from ‘Browse’ tab.<\/p>\n
