I hope that I am putting this information in the right place.
I would also like to preface this problem with the 
statement that ubuntu 8.1 and XP have a similar 
track record with this problem with me.

I have a 
2.6.24-23-generic (#1 SMP Thu Nov 27 18:13:46 UTC 2008)Kernal,
gnome,quad6600, atiradeon rv250(open source driver), 
intrepid 8.1 all updates no (compiz or fusion or) 
desktop effects.

I recently bought a new monitor.samsung 2333SW lcd 23".
the monitor is not recognized by the capplet
(configure display settings).
the resolution is not optimal.
I do not know how to change the resolution.
I have forgoten the comand for my Xorg version 
and the version does not show up in the sysinfo application.
the current resolution is 1024*768 48Khz 60Hz NN.
the best resolution is 1920*1080.
My situation is improved from the previous monitor 
but I am hopeful that I will be able to use the 
better resolution soon.
perhaps I will find more information on this issue
if I use different search key words but this was 
the closest I could find.
It would be nice to have a few more designated 
key words(areas or connections in the database)
ATI,MONITOR,Nvidia

above I noticed that there was a request for some info.
I have provided it below.
