First generate a "modeline" by using cvt

Syntax is: cvt width height refreshrate

cvt 1680 1050 60

this gives you:

# 1680x1050 59.95 Hz (CVT 1.76MA) hsync: 65.29 kHz; pclk: 146.25 MHz
Modeline "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync

Now tell this to xrandr:

xrandr --newmode "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync

Then you can now add it to the table of possible resolutions of an output of your choice:

xrandr --addmode VGA-0 1680x1050_60.00

The changes are lost after reboot, to set up the resolution persistently, create the file ~/.xprofile with the content:

#!/bin/sh
xrandr --newmode "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync

  The connected device might not be VGA-0. If you get the message xrandr: cannot find output "VGA-0", try running the following command: xrandr | grep -e " connected [^(]" | sed -e "s/([A-Z0-9]+) connected.*/1/" (source: xrandr on ArchWiki). The output of that command should be the correct device identifier.

Thanks to thom and thirdender this is basically a single command configuration based on the most voted answer.

RES="1920 1200 60" && 
DISP=$(xrandr | grep -e " connected [^(]" | sed -e "s/([A-Z0-9]+) connected.*/1/") && 
MODELINE=$(cvt $(echo $RES) | grep -e "Modeline [^(]" | sed -r 's/.*Modeline (.*)/1/') && 
MODERES=$(echo $MODELINE | grep -o -P '(?<=").*(?=")') && 
cat > ~/.xprofile << _EOF
#!/bin/sh
xrandr --newmode $MODELINE
xrandr --addmode $DISP $MODERES
_EOF

The above command will generate the desired ~/.xprofile file. Just make sure you use the resolution (i.e. the RES variable) of your liking. More info here.

Thanks to thom and thirdender this is basically a single command configuration based on the most voted answer.

RES="1920 1200 60" && 
DISP=$(xrandr | grep -e " connected [^(]" | sed -e "s/([A-Z0-9]+) connected.*/1/") && 
MODELINE=$(cvt $(echo $RES) | grep -e "Modeline [^(]" | sed -r 's/.*Modeline (.*)/1/') && 
MODERES=$(echo $MODELINE | grep -o -P '(?<=").*(?=")') && 
cat > ~/.xprofile << _EOF
#!/bin/sh
xrandr --newmode $MODELINE
xrandr --addmode $DISP $MODERES
_EOF

The above command will generate the desired ~/.xprofile file. Just make sure you use the resolution (i.e. the RES variable) of your liking. More info here.
