you've got to set your screen refresh rate and resolution in the X config file. There may be a guis managment console to allow this or you can run xorgconfig to set it up get on the net and find the information from your LT manufacturer before you set this some newer monitors have safety valves in place to disallow invlid settings but those that don;t can get toasted by wrong settings you need horizontal and vertical refresh rates.
Make sure you've got your video card set right. when the screen refresh rates are properly configured you will have more choices under screen resolution.

This might help you with your network issues do you have a netowrk card/dsl router-modem setup or is it usb/dsl modem-router? at teh command prompt enter the command "/sbin/ifconfig" this should show your current network card config.
you should see something like this:
Code:
eth0 Link encap:Ethernet HWaddr 06:D1:2A:66:19:00

lo is my internal local network
eth0 is my ethernet card and it shows I have a proper ip address
if you don;t have this or somethng like it you may not have a card setup, the only sure way I know to set this up I won;t go into here. The Ubuntu site should have some documentation on adding a card. If not you can do it manually (once you fidn the driver )
Configuring Linux to talk to your network card
this page might be help if you really have to manually add your card
