Dual Monitors Not Working

Post by Toast550 »

When i set number of monitors to two and start my vm only one window appears. I've tried clicking view and then under virtual screen 2 click enable but that does nothing.

Im running Arch Linux under a windows 7 host.

Virtual Box Guest Additions are installed on arch.

I've also tried reinstalling virtualbox.

You need to configure the guest OS to use these two monitors. This is like on real hardware. Adding a screen doesn't mean the OS will use it, especially if you're in CLI mode!

My Desktop environment is Xfce4 but that only shows one monitor in the display configuration.

I've looked up the tool for using dual monitors on the arch wiki and it says is RandR.

But when i run randr only one display is listed
