I have an Ubuntu 17.10 installation and I would like to connect two Nvidia GTX 1070 graphic cards and use the Nvidia official driver instead of the Nouveau drivers.
I have tested the following versions of the official drivers:
390.25
387.34
384.111
With each one I have no problems to boot up using a single graphics card, but with two I get stuck on the purple screen of death.
I tried to disable the purple screen so that I can diagnose the error, but I even failed at that.
I feel pretty much stuck in here, so any hints whatsoever are warmly welcome.
