Thanx for your advice!
I just tried with the radeondeinit on and the nvidia_drv off, sysdef 18,3 and it boots well up to clover for some strange reason with a higher resolution, but I won't complain. The apple logo loads, it hangs a long time halfway (like with the nvidia card) and then there is a big white flash and the screen goes in sleep mode..... I'm a bit puzzled.... maybe my whole config.plist is a mess, I don't know!
Hit space bar and select verbose then boot and see where it ends.
Probably IOGScrenlockstate.
iMac 17.1 and 18.3 have been troublesome for some users. Did you uninstall Nvidia web drivers?
