You’re making a minor mistake in /etc/X11/xorg.conf
Section "Monitor"
Identifier "HDMI1"
Option "PreferredMode" "1680x1050_60.00"
EndSection
You need an extra line (real life example, not yours):
Section "Monitor"
Identifier "VGA1"
Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
Option "PreferredMode" "1280x1024_60.00"
EndSection
To setup the Modeline values you need to use:
cvt 1680 1050
copy and paste the output values to your /etc/X11/xorg.conf. In addition
to the “Monitor” section you should have a “Screen” and “Device” section as well.
