I've done the following:
Code:
$ cvt 1440 900
# 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
sta@WDElinux4:~$ xrandr --newmode "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
$ xrandr

v: height 900 start 903 end 909 total 934 clock 59.9Hz
$ xrandr --addmode VGA1 1440x900_60.00
and 1440x900 is available in gnome-display-properties.
BTW to hardcode these settings after restart, pls add in /etc/gdm3/Init/Default,
before exit 0, the following lines:
Code:
xrandr --newmode "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
xrandr --addmode VGA1 1440x900_60.00
