I had an ODROID-XU4 sitting around in a drawer with a happy installation on eMMC. I've decided to actually use it for something, and so before getting started I decided to update its packages. One of them was a new kernel.
Now I can only see seven lines from the console. Further lines are blank. Running clear to get back to the top of the screen works just fine, so I can do some amount of work on it, but it's a bit difficult to use this way.
Is there something in particular I should go fuss with to try and fix this? I'm not yet sure where to start looking. Thank you!
