Its been a while. Playing around with screen resolution on a atrix lapdock for beaglebone black and machinekit

I’ve been playing around with machinekit lately and I’ve gotten around to using with my Beaglebone Black with a Cramps board.  It’s been a huge amount of fun.   I had a Atrix Lapdock that I wanted to use but I was having some issues with screen resolution.  This can be a little troublesome since I can’t to shut off warning messages that pop up.  The other issues, that I’ve been having is that if my usb is plugged into the bbb while it’s booting the keyboard and atrix mouse don’t work.  If I plug the usb in after boot up, it’s fine(weird)

The Atrix lapdock screen resolution is 1366 x 768:

So I was looking at a post   and  came up with this per the suggestion to add to  uEnv.txt

Well, that didn’t work. Then a little more googling brought me to this.

which suggested adding this to the uEnv.txt file:

optargs=quiet drm.debug=7 capemgr.disable_partno=BB-BONELT-HDMI video=HDMI-A-1:1360x768M@60

That worked.
