Generic LCD Display:
LCD Panel 1024x768

so thats when i got this message:

Display settings changed
You need to log out and restart the X server for the changes to take affect.
Configuration was written to /etc/X11/xorg.conf, original configuration saved as /etc/X11/xorg.conf.backup

so if after you have made changes to your display and when you reboot you can't see anything, try login in as single mode and replace the configuration file with the original
