Need help with Single User Mode

[Source]

Hi guys,

So I just installed SwitchRsX which is an app which allows you to create a custom resolution for your display (so instead of 1680x1050, you could do 1680x960).

The trouble is that now when I've restarted, I get a black screen.

As a last resort, if you can't even start SwitchResX itself, you'll have to delete the monitor profile that was modified when you created a new custom resolution. This file is located in /System/Library/Displays/Overrides/ and is the last modified file, that you can find if you sort by date. You should remove this file, if you can access the file system, either by
1) accessing the file system from an other Mac on the network, from ssh or by mounting a shared folders.
2) OR starting up in single user mode (or safe mode)
3) OR at last resort: reinstalling the OS above the existing install, which will keep your existing profiles, but remove the system modified files.

Can anyone tell me how I can find out which was the most recent modified file in Single User mode?

Thanks.

After booting into Single User mode, you'll need to run a file system check and then mount the file system. The instructions for doing these steps should be right on the screen in front of you. Once the file system is mounted, you should enter

ls -tl /System/Library/Displays/Overrides/

(The first character is a lowercase L, as is the character before the first /)

You should see a list of files, along with their modification dates. The most recently modified should be first. Instead of deleting that file, it's probably better to just move it out of that directory. That way you can recover it if you need to or if you made a mistake. To move it out, enter

mv name-of-file  /

(name-of-file should be the exact file name---case matters)

Then enter

reboot

to exit Single User mode and boot OS X.
