thought I get back and post how it all turned out.
First of all, turned out it wasn't 6th GPU specifically, Xserver crashed randomly but the more GPU the more chances of a crash.
It's my mining rig which runs okay under Windows so I was a bit puzzled. After about 2 weeks I tried again and it worked as advertised. Either motherboard bios upgrade is the reason (MSI Z77A-G45 bios v 2.12) or some ubuntu packages where updated in the meantime. I have already 2 of the rigs converted to ubuntu and they are running okay for a week now.
Time to do some hashcating!
