I got my mini about 5 months ago and immediately put OSX on it, but went back to Ubuntu & Windows after a few days of fun because I had to get a lot of work done, and my original plan was to have at home a "desktop" mac with big monitor, but light Ubuntu when on the road, and Windows for compatibility.
So I just spent the last 12 hours putting together a perfect OS X 10.5.8 install (running entirely off a 16gig thumb drive), except of course for one thing: I have this beautiful 23" Dell 1920x1080 widescreen monitor, and when I running in "desktop" mode, I want ONLY the external monitor to run. Piece of cake in Windows7 & Ubuntu9. Not too hard on the Mac side of things either... I just have to "Fn 8" twice immediately at boot time to switch off the laptop display and switch on the external monitor display.
Unfortunately, the mac won't boot up all the way to desktop unless I install the "old" kext, or unless I have the (annoying) laptop display turned on too. As many of us know, the old kext is fine except for the screen artifacting, which is also incredibly annoying. I don't quite understand the issue here, and why either the old kext can't be fixed to get rid of artifacting, or the new kext can't be fixed to allow full boot with only the external display turned on. I really don't know anything about OS X, having used mostly Linux for the past 10 years, I don't even know what a kext is. Maybe if someone can give me a few clues as to what the issue(s) are about using the new kext, I can set about to try to code a solution myself?
Any help or advice is very welcome!
