Screen names in Display configurations

[stz_comp]

Hi,

I've a little problem, nothing serious, but it's quite irritating. I have AMD64 Ubuntu Jaunty with 9.6 fglrx driver of my Ati Radeon HD 3450 graphic card and two monitors. This is the only version of driver, that is working properly on my PC, but In Display configurations are both screens called as Unknown. Is there a way how to call them in xorg.conf? My attempts of configuration usually last with black screen after boot. :D
Thanks.

This is my xorg.conf:
