ok thanks...can i download that on my windows computer and then transfer it over to my linux computer via flash drive? cuz i think i have a bad modem or something cuz i havent been able to get my linux comp on the internet and im stuck with dial up out here on this hill :P
hmm one more thing....when i just typed it into root console to see what would happen it said

root@shanes_knoppix:~# apt-get install xorg-dev
reading package lists...Done
Building dependency tree... Done
Package xorg-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obseleted, or is only available from another source
E: Package xorg has no installation candidate

im pretty sure that just means it cant install the package cuz its not online to download the package right? or do i need to change something that is messed up?
