Raw
xrandr-custom-resolution.md

Find the maximum resolution

xrandr | grep maximum

Use gtf to create a mode line

Copy the mode line from gtf and create the new mode in xrandr

xrandr --newmode <paste gtf modeline here>
e.g.
xrandr --newmode "1440x900_59.90"  106.29  1440 1520 1672 1904  900 901 904 932  -HSync +Vsync

Add this newly added mode to the desired output (VGA/LVDS etc)

xrandr --addmode VGA 1440x900_59.90

Select the new mode

xrandr --output VGA --mode 1440x900_59.90
