Hi, first of all, this is my very first day using Linux (Red Hat 9)

I completed the installation yesterday. I wasn't sure if there would be problems but I installed all of the packages!! (let me know if that was wrong!!!!) Also, forgive me if I put any Windows terminology in this post....I'm not certain as to what to call everything!
I'm having a problem viewing my full Windows. I've done the obvious by going to the Main Menu>System Settings>Display, I can change the resolution (from 640x480 up to 1920x1440), but after it asks for a logout (reboots) it's still the same.
I've read three posts that seem to match my problem with these results:
1) XConfigurator gives this error
-bash: xconfigurator: command not found
2) ctrl+alt+[plus sign] AND ctrl+alt+[-]
nothing happens
my specs - IBM P2 350Mhz, 128MB RAM, 8GB HDD, S3 Trio3D on board video
Is there something else that I can try? Note, I'm really not a programmer, like I said I'm 2 days old into Linux. Also, when in the Xconfigurator screen how do I exit out. I did a Windows (ctrl+alt+del) cold boot and it rebooted, is there another way to go directly back to the desktop (is that the correct term??)??
Thanks in advance for the help, expect to see more questions!!

My next project - connecting to a Win2k Network......
