Catalyst 16.9+ drivers do not allow 6 GPUs in Win7 even with 6xGPU patch. Try Win10.

To troubleshoot ubuntu it is required some more information.

1. /var/log/syslog
2. /var/log/Xorg.log or smth similiar

have you added your user to video group?

I use ubuntu 16.04 server on my rigs with no bugs. Try it maybe

Yes , I have added the user group accordingly as shown in the video here https://www.youtube.com/watch?v=d1ok9wLc3dE
and as soon as i restart i stuck at the login loop .

You have just mentioned 16.04 Ubuntu server and I am using 16.04.1 desktop version
does it make the difference

Should I try to use Server Version ?

But according to mention in the video

Command I use to in the video group - sudo gpasswd -a $(whoami) video
and then reboot and stuck in login loop

are you using 16.04 Ubuntu Server or 16.04.1 Ubuntu server

downloaded ubuntu from here -http://releases.ubuntu.com/16.04/ 64 bit version

Does changing from desktop to Server will work ?
