I've got 15.09 installed on my 410c and when the HDMI display goes to sleep there's no way to wake it up (via keyboard/mouse input, anyway).
Can I just disable display sleep completely?
I was able to do this by adding the following to my ~/.bashrc:
setterm -blank 0
i am noticing this issue now.. we will look into it. it looks like something new since we switched from 4.0 based kernel to 4.2..
please see https://bugs.96boards.org/show_bug.cgi?id=165.
i can confirm the problem.. and it should be fixed in our kernel in a few days
