*Turn off your Visual Effects and the dual/extending monitor works!!
Well this is probably nothing much for most people. It is, to me, that the dual monitor thingy is finally working. The thing is, I am using two monitors here and Ubuntu 9.10 RC’s did not support them to work side by side. Now it is and I can type on one screen a search on the other. Guess what? 
Happy as a clam!!
[I went to my office and did the same thing on my TravelMate 3000 (I have a 3010 at home) and it didn't work. Turned out that it worked right after I changed the Visual Effects to None. So, maybe it's been working? Stupid me/Ubuntu!]
