Thanks, linuxdev.

We have corrected it to the right one.


I have installed SDK manager ( but using a 768p monitor, I was unable to complete step2…the controls are below screen.
Do these GUI designers consider everyone has at least 1080p monitor, and no need to use scroll bars for lower resolutions ?

For anyone facing similar problem, a workaround was to use xrandr to scale with a factor 1.2 in my case (using this monitor as DP-1):

xrandr --output DP-1 --transform 1.20,0,0,0,1.20,0,0,0,1

I have the same issue with JetPack…my only Ubuntu install is on a 10" dual core atom laptop. I do remote display to my Fedora desktop in order to run JetPack for no other reason than the GUI size.

Good workaround.
using xrandr first to update the primary monitor choice.
