i got from my friend last week his unused G5 (PowerMac G5 Late 2005 DualCore Model @ 2GHZ, Nvidia 6600 GPU) i formatted it clean after backing up and uploading his data to him. (WAS NOT FUN leaving my connection unusable for half a day to upload nearly 70GB.)
i want to Dualboot this G5 w/ Leopard & MATE but when starting up w/ "live video=ofonly nouveau.modeset=0" i get a Corrupted Display and upon trying to shut down or reboot it hangs at a black screen.
You can also try: “nouveau.noaccel=1” instead of “nouveau.modeset=0” this should get you at least a useable Desktop (even if it´s not 2D-accelerated by the Card)
