sudo apt-get install arandr
arandr

If all your monitors are stacked in the same space, the space is not wide enough and you can't really move them, you need to switch to a proprietary driver. If it works with the open source driver for you, do not bother using another one.

For ATI cards:

  • install fglrx and fglrx-amdcccle
  • reboot
  • run the ATI configuration tool (amdcccle; if the binary is unavailable for you, locate and run it directly -- it's probably at /usr/lib/fglrx/bin/amdcccle).
  • Configure your monitors there and restart X (or your whole machine).

If your layout is still messed up (sometimes happens) you can at least use arandr now.

For nvidia cards:

Probably something similar (we don't have any on our office machines).
