hi all,

I have an issue where I must not have selected X at install time as its 
not there.
I dont have networking on this box.
I can put the DVD back in unit but I dont have X to run and to software 

How do I do this from the command line with no network so no yum install 

so mount the DVD, cd into the RPMS directory then what command do I run to
install all packages for X from the current directory.
