Woher weißt du das?
Das mit dem Bug finde ich jetzt auch sehr interessant.
Konnte jetzt auf die Schnelle auch nichts dazu finden. Hast du vielleicht einen Link, Dragonforce?
habe gfxCardStatus komplett deinsalliert. der fehler tritt immer noch auf
...
Das liegt daran, dass gfxCardStatus seit 2.2.1 die sogenannte "Switching Policy" systemweit ändert. Deswegen ist auch die Anzeige unter den Energiespar-Einstellungen anders. Hier vom Entwickler selber:
The bit of code in gfxCardStatus that makes the black/garbled screen thing happen works great on every other kind of MBP model except for the 2010s, and only a limited subset of them, at that. My 17" 2010 machine is fine. Some folks' 17" machines aren't fine. I have one friend whose 15" machine works great, which boggles my mind, because I thought it was all 15" models from 2010, but apparently not.
v2.1 switched a little differently than v2.2.1 does. But as I said before, this issue only happens on certain 2010 machines. I'm going to have to go back to the old method of switching in the next update, but only if you're using a 2010 MacBook Pro. It's annoying, because that's a shitty workaround, and this problem shouldn't exist in the first place. The switching hardware was just shittily designed in the 2010 machines.
The issue with going back to the old method is that there has been a significant bug in gfxCardStatus for a while where if you're on Integrated Only, and you quit certain apps, OS X gets confused and kicks the discrete GPU on. The new switching method fixes that. But if I go back to the old stuff for 2010 users, they no longer have that fix.
The changes to the Energy Saver prefpane are intentional in v2.2.1 - gfxCardStatus changes something called the switch policy in order to basically completely disable automatic switching. Changing the switch policy is also what's causing the problem with machines with hardware issues.
