Hello Peter, I might actually have a 6600 and 7800 laying around so if I can I post results of those as well, but it may be just a couple of days.
Of the three issues I will start with the first. I will touch base with the nouveau developers and see if they can revisit the issue soon and offer my help in any way. I am not an experienced graphics developer but I've been doing a lot of reading of the nouveau driver documentation as well as Linux graphics in general so I'm at least trying to learn what I can as I don't want to see support for this great Mac model go into the sunset just yet. No better way than to just dive right in. Thanks, Brock Sent from my iPhone > On Jul 3, 2015, at 2:39 PM, Peter Saisanas <psaisa...@gmail.com> wrote: > > Hi Brock, > > That's great news!
