Ok, i tried that and then when i replaced my old xorg.conf with the new one i realised that the new one was MUCH MUCH smaller (and when X runs with it it get a lot of parsing errors and font missing)
.. it was already done.. to undo the changes i replaced it back with xorg.conf-vesa (they seemed to be the same file with small changes)
to set this new xorg.conf i used:
It enters on an pretty config form, there i found my Video Card and it´s driver.
The problem is that, now, the X is still not working, now it gets stuck in a black screen.. no way to get out, just rebooting at the power buttom.
If anyone knows the solution.. please help!!
