    need some help with dual monitors and an ati card

    trying kubuntu for the first time. im really liking most of it so far.

    i'm trying to get dual displays working on my computer. im a bit of a linux n00b, but i can get my way around fairly well. i have been searching all day for a solution to this problem and all i can fine are little bits here and there that seem to get me no where. i was hoping that someone could just tell me "this is how you do it" and all will be cool. just did another fresh install (i broke that last install trying to make this work) and ive installed the ati drivers from the internet. ive done no other configuring. from what ive figured out from my last attempt is that i cant get it to work because randr 1.2 is enabled. ive gotten it to the point where i have both monitors working separately (not cloned) where one has the desktop and the other is blank except for an 'X' for the cursor.

    can someone please help me with this?

    EDIT:
    so, ive tried doing what this guy suggested at http://ubuntuforums.org/showthread.php?t=1129989 and the control center lets me enable the 2nd display, but it still doesnt give me a span option. the 2nd monitor is now black and when i move the cursor to it the little black X just moves around the screen. nothing will display on it. i must be missing something stupid. i also tried to run several aticonfig commands to enable the other desktop and nothing seems to do the trick.

      I used xrandr. It works very well. I had to edit my /etc/x11/xorg.conf (create one, actually) with the proper virtual desktop size (2560x1024 for me):

      Section "Screen"
      Identifier "Configured Screen Device"
      Device "Configured Video Device"
      SubSection "Display"
      Virtual 2560 1024
      EndSubSection
      EndSection

      Rebooted and then ran arandr.
