Automate desired resolution at login

[jeb at askur.org]

When I log into X I seem to have the wrong resolution (My screen: vga
19"LCD envision rated at 1440x900). I am able to get around that by typing
the following:

xrandr --newmode "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903
909 934 -hsync +vsync
xrandr --addmode VGA-0 1440x900_60.00
xrandr --output VGA-0 --mode 1440x900_60.00

I haven't been able to figure out how to make this happen automatically,
i.e. how to save this as the default mode at login.

If you look at the log excerpt which is attached you see that there are
some modes selected there but I don't know how to change that. I don't
know where those modes came from.

Trying Xorg -configure was unsuccessful due to "Number of screens..."

Could you make any recommendations or point me in the right direction?

Thank you, Jon.
