Display setting problem -

[Bob Goodwin]

I have a ViewSonic VX2035wm LCD Display monitor on this computer that is 
not recognized by Fedora-18. in order to get a reasonable display I have 
to run /usr/bin/xrandr -s 1680x1050 after I am logged in and the display 
[XFCE] is running. That works for me but it seems a bit clunky and after 
doing so for more than a year I would like to find some more elegant way 
to deal with it.

I could use a different monitor but I prefer the aspect ratio of this 
one, it's wide but higher than the others available.

Anyone know a better way to deal with this? As it stands it is just one 
of the things I do every morning after booting the computer ...
