How do you determine that it doesn't detect the monitor? You can read through /var/log/Xorg.0.log, but it's easier to just run "xrandr" (when both screens are connected) and see what it detects. If "xrandr" is able to detect both outputs it should just be a matter of configuration, if not then that would suggest a problem with the driver. At least Wheezy is a lot more up to date than Squeeze, with newer kernel and X. I'd say your odds of getting the second screen going there would be a lot better than with Squeeze. Since it's working on your Ubuntu installation, can you determine which version of the driver that has installed? The packages are usually called "nvidia-xxx", then do "apt-cache policy nvidia-xxx" on the one that is installed to see the exact version. Do the same for Wheezy. Copies of Xorg.0.log (on both Wheezy and Ubuntu) would also be helpful, just to see what your system detects, and how they differ. Petter -- "I'm ionized" "Are you sure?" "I'm positive."
