No, actualy I've done everything right, but I think the Linux kernel is some sort of confused, once I tried to set up the card WRONG, it did the job, and did set the resoloution up at 1024 but when I clicked on OK, everything reseted to the first configuration ! but I guess it's because of my monitor, mayB, because Linux can't probe my monitor completely, just named it Unprobed Monitor. anyway, something interesting, the last time I installed Linux on my computer, I had an other Monitor which was a 14" Acer monitor, and I could set the resoloution to 1024x768 but now, with this monitor, I can't, because of this, I say mayB the problem is because of my monitor !
