Pretty sure this is something really simple...but I can't get a login to the desktop 
I get a prompt with either m1 or Guest session and the password miner1 doesn't work for me at all.
It seems to take it but just jumps back to the login screen again

I'm having this same issue
Setup the rig via hdmi to my tv and it was running great, brought rig out to garage with monitor and display port cable and it won't login
Put in the password and it just loops back to login page, doing the console reboot doesn't help, even trying to use startx from console gives a bunch of errors "failed to set IOPL for I/O (operation not permitted) and fatal server error: (EE) no screens found)
