Monitor "out of range" - Ubuntu 9.1

Hi, I'm running Ubuntu 9.1 and when as I login as me (adminstrator) the monitor is: out of range. However, I can still login as the other users of the system. In addition I installed Ubuntu a few days ago and logged without a problem between before now.

My computer is new but the monitor is very old. The monitor refresh rate in this user (not admin) is 50 Hz but I seem to remember that in my account the refresh rate was about 60 Hz. Could it be that the monitor does not function at 60 Hz and if so how do I change it under my login? Also it said that the monitor is 'unknown'.

Furthermore, when I go to > system > preferences > display it says that my "graphics card does not support the extensions for this tool" and it gives me the option to "use the graphics driver the vendor's tool instead". I'm not sure how that is relevant but just thought I'd mention it.

If you want avoid phisical damage on your monitor don't use frequency don't supported by your monitor.

For the other questions, simply said that some functionality (probably 3d, effect on compiz, etc) aren't supported if you don't install the proprietary driver.
