Hello, I had everything running smoothly but then I went into System Preferences –> Displays and wondered what the overscan option does. I clicked it, the screen went black, and since then, I can't get it working again. Fortunately, I can still log in and see what I'm doing using the iGPU but nothing seems to be working. I erased display preferences (~/Library/Preferences/ByHost) and reinstalled the Nvidia driver, but to no avail. Any suggestions, please?
EDIT: Telling others about my problems apparently often does the job equally well, i.e. I somehow solved it, possibly by booting in a safe mode (boot flag -x), removing com.apple.windowserver.whatnot in ~/Library/Preferences/ByHost, and rebooting again, and again after activating the Nvidia drivers in the pref pane.
Interestingly though, this time the overscan was active (the checkbox is checked) and when I unchecked it… hello darkness my old friend. Anyway, I repeated the procedure and got it working again, however that bloody checkbox is still checked, thus I'm still interested in learning what's going on. Thanks!
