You can connect multiple virtual displaysīefore you do anything make sure you are using Ubuntu 22.04 LTS or a Linux distribution based on GNOME 42. How to Enable Virtual Monitors in GNOME 42 While this kind of feature is not ‘new’ new – it’s been possible to use tablets as external monitors (including on Linux) via a local network for a while – what is new is that all of relevant components to make this work well come baked into GNOME 42. You can also ‘drag’ your virtual monitor to your desired location directly from the Settings > Display panel, where you can also adjust the virtual monitor’s screen resolution independently of your main display. The virtual monitor behaves like a regular monitor.
In a nutshell, on any Linux distribution using GNOME 42 you can use a RDP-supported device (e.g., an Android tablet, an old iPad, another computer) as an external monitor in much the same way as Apple’s SideCar feature (which lets macOS lets users extend their desktop on to an iPad screen).
To help, GNOME devs plumbed in frame tracking and enhanced hardware acceleration to ensure we get a smooth experience (though as this is still network dependant don’t expect miracles). Now, using a tablet as a second screen using RDP asks a little more of performance than just being able to access a desktop over RDP (which can be pretty laggy). This included the ability to extend the desktop on to a virtual monitor as though it were a real one (including respecting any multi-monitor preferences you have configured).
We have GNOME developers to thank for this.Īmong the various GNOME 42 features were a number of changes relating to the desktop’s support for the remote desktop protocol (RDP) and screen sharing.
