    NVidia Geforce2Go and external LCD monitor


    Hello everyone,
    I have Linux Mandrake 10 (kernel 2.6.3-9mdk) installed on my laptop (Acer Travelmate 630) with a NVIDIA Graphics card (GeForce 2Go). I have the latest NVIDIA driver installed and it has worked great for a while (laptop LCD resolution 1400x1050).
    A couple of days ago I bought an external LCD monitor (Acer AL1711 - 17inches) to connect it to my laptop. Supported resolution on this LCD is 1280x1024.
    I have tried to make this LCD work with my laptop for 2 days but without any luck.
    I have changed my XF86Config-4 file looooads of times, adding new ad-hoc modelines, changing all the relvant sections but nada (blank screen- crashes).
    I also tried uninstalling the NVidia driver and use some of the distribution default drivers instead. I managed to get some 800x600 using the generic NVidia driver ("nv") - but it gets totally messy for higher resolutions - and using the generic "vesa" driver I get a good 1280x1024 but it's a total waste of the graphics card (and playback of movies is crap).
    Any suggestion greatly appreciated.
    I attach my XF86Config-4 file. (You may notice that I have two sections for "Monitor", "Screen", etc. which get selected in the "ServerLayout" accordingly.)
    Thanks,
    albe
    p.s. my hotkey (Fn+F5) switches perfectly between monitors.

    have you tried lowering the resolution? U say you have your laptop running at 1400x1050 but the external monitor only supports upto 1280x1024. if u lower the res to 1280x1024 or even lower, this hopefully will work.
