View Full Version : single user mode display identification command needed

Jul 14, 2012, 05:37 PM

Thanks in advance for any help on this issue.

I have swapped displays between two MacBook 1,1 computers. (One had a display that was cracked and the other had a dead motherboard). Now I can only boot into single user mode (command-S while starting up). The recipient of the new screen gives errors like: "GFX0: family specific matching fails" and "display: family specific matching fails"

I need a command to use from single user mode to identify the transplanted display's identity.

Then I plan to modify the EFI so that it is again happy with the new display.

Anyone know the code for display identification?

Thanks again.


I found this command via google

ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6

but it only works from the terminal, which I can't get to. I can only access the command line via single user mode.

So, I need different information...
