I believe this works on the Raspberry Pi although it may depend somewhat on the firmware version and/or device tree you use. You'll need to boot the board with the monitor connected and turned on for this to work. There is no acceleration for the framebuffer.

What resolution would the display apply?

In principle yes, as long as support for it is enabled in U-Boot. Currently that's only the case for the TheoBroma Systems "puma" RK3399-Q7 board. I think the driver only supports HDMI output right now. > What resolution would the display apply? Not sure if there are any limits; 1920x1280 defenitely works on sunxi boards, so that probably would work for RK3399 as well.

Sometimes there are more displays, e.g. the Theobroma has both HDMI and DP. The Samsung Chromebook Plus has a built-in display and also HDMI via USB-C [1]. Resolution and port switching logics would be all in the firmware then, right? Do you have any guess if the Chromebook Plus RK3399 would have a firmware framebuffer? Should you be able to run X using the wsfb driver on the firmware framebuffer? [1] https://www.samsung.com/us/support/answer/ANS00061883/

I am able to run X on my Pinebook, using the framebuffer. arm(v7,64) is very much a "you'll almost certainly need to try it, and make sure you have updated firmware^W u-boot" platform. -- Real Time, adj.: Here and now, as opposed to fake time, which only occurs there and then.

These are openBSD port/packages that you'll install on a amd64 machine where you will write your SD card image from. Obviously you can't install these applications on the rock64 if you can't boot it up.
