This can be chipset and driver dependent. One desktop mother board had an Intel graphics chipset that would not talk to my 1400x1050 desktop screen through the DVI port. That mobo got returned. Assuming that your laptop graphics chipset (which?) was designed to talk to your 1440x900 screen, you may be having a software driver problem. Some drivers suffer from programmer "IWFMIDCAY" ( "It works for me, I don't care about you" ). If the driver doesn't support the resolution, xrandr won't see it. Fortunately, many chipsets have more than one driver. Sometimes, only the open source one works. Sometimes, only the proprietary one works. Look at /var/log/Xorg.0.log . Your driver may list the available modelines there. If 1440x900 is not listed, you need to find another driver. If the log file shows the EDID information, you can find a EDID parser program to interpret that. If you are hypergeeky, you can decode the EDID bytes manually. That will tell you what the screen actually supports.
