NVidia Geforce2 Go 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.
