The xorg.conf provided is the default xorg.conf generated since installation.
The only change was that "PreferredMode" was changed. I will attach another
copy of the dmesg log collected after the command 'xrandr --output DP1 --mode
800x600 --rate 72.2'. Are there any ways that I can use to specify the modes?
