As a preview of what's going to be possible in the upcoming release of #GrapheneOS, here's a screenshot from a Pixel Tablet running desktop Chrome in a virtual machine with basic GPU acceleration via ANGLE on the host. The infrastructure is a lot more robust than the Terminal app:

Our next release also enables running the Terminal app in secondary users. There's still the temporary limitation of only being able to use a single VM on the device at a time because the dedicated internal network interface it uses for the Terminal app isn't split up at all yet.

GUI VM support will have 2 main use cases:

1) Running a specific app or an entire profile via GrapheneOS virtual machines seamlessly integrated into the OS.

2) Running Windows or desktop Linux applications with desktop mode + USB-C DisplayPort alt mode on the Pixel 8 and later.

This virtual machine management app (Terminal) will be handling the 2nd case. It's essentially already available in a very primitive way. We expect this to become much more usable and robust entirely from the upstream Android work on the virtual machine and desktop mode features.
