I modified the Xavier default resolution but can't boot now!

I modified the Xavier resolution by modifying the file /etc/X11/xorg.conf, but I can’t boot now, system is stuck in the following:

I added the following to the file:
Section “Monitor”
Identifier “Configured Monitor”
Modeline “1024x768_60.00” 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
Modeline “1440x900_60.00” 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
Option “PreferredMode” “1440x900_60.00”

Section “Screen”
Identifier “Default Screen”
Monitor “Configured Monitor”
Device “Configured Video Device”

Section “Device”
Identifier “Configured Video Device”
Now I can’t get into the desktop, Is there any way I can delete these files ???

Maybe I failed to upload the image, how to upload the image ?

what if you press Cntrl+Alt+F2?
will it show the text mode display?

FYI, xorg.conf will not work quite as expected compared to a desktop PC. The driver involved only accepts modes from the EDID response of the HDMI cable (so for example, a VGA cable would fail since VGA doesn’t have the DDC wire for the EDID response). Some setup will still work in xorg.conf, but others referring to mode lines and resolutions will be rejected (the modes and modeline content must come from the EDID).

Thanks a lot!
after trying,i found i can switch to tty2,although the screen has been blinking on the error screen and tty2 interface, I finally modified the file and successfully entered the desktop.
