I am totally newbie with linux... I installed the slackware 9 ( I actually succeded....*proud* ) But now that i have installed the slackware 9.. i don't know wich command to type to get to the X mode ( i have set KDE to the default X something

) So what command do i need to type ? And i saw there was a X mode that looked like windows, Can i change to that mode later ? then, how ?
(speak friendly, i don't understand much of the "linux words")
