i messed up on something. i was playing with my desktop resolution, so i wanted to make it bigger size so i went into the configurations and i changed them. then, it gave me a message that said that my backup configuration was put on some directory. i am so dumb because i didnt write down the path, now i have no idea how to put the gui back because whenever i reboot, there is nothing on my screen but black screen

so i want to know if there is a way to show or display all the files that were created for the last 20 minutes or so?
