not recognised automagically.

Run

Code:

cvt X Y

Replace X & Y with the values you want.
This will produce something like

Code:

# 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz
Modeline "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync

Then add a new mode using xrandr

Code:

xrandr --newmode big 106.50 1440 1528 1672 1904 900 903 909 934

Replace big with what ever you want and the numbers to that of the output of cvt
Now add the the mode to your output.

Code:

xrandr --addmode VGA-1 big

VGA-1 might be different, type xrandr --output and then press tab twice and you will get a list of outputs

Now make that output use the mode

Code:

xrandr --output VGA-1 --mode big

With a bit of voodoo chanting you should now have the new resolution.

Note that this is a quick and dirty way of changing to a custom resolution, and after a reboot the resolution will go back to the old one.

If you screw up just reboot and the resolution should go back to normal.
