Click this image to see the OS information in detail. This shows a nice GPU accelerated Qt5 Widget example.
You can find the OS image link from this official release note.
Ubuntu Minimal image will be available in two weeks later hopefully.
If you are interested in running the mainline Kernel 4.17 or higher, visit this forum thread.
As far as I heard, there are some critical issues with display output.
So it is useful only for headless application like a server or IoT area,
Note that we couldn’t find any way to upgrade to 18.04 from 16.04 due to very complicated dependencies.
So you have to backup your important data and freshly flash the OS image.
