ok, I have a couple of problems and I will list them all. Maybe anyone can give me a tip, as soon as I will find a solution I will report here.

1. I am still getting low graphics mode when using more than 6 cards. I can start mining with SSH and bash 2unix but unfortunately mining doesn't autostart anymore after reboot. anyone has a tip on how to fix low graphics mode, or disabling GUI or other way to autostart mining?

2. somehow rigs dont do sudo shutdown or sudo reboot. they loose SSH connection but nothing happens. need to power off.

3. will it be very hard to implement telegram, auto temp, wtm profit switcher from nvoc? I am looking forward very hard to build an image and if working, I am willing to distribute.
