I am totally new to Linux, i installed it yesterday, since than i my fans are really loud, i did not have this problem on windows.

I saw this post on this site How to control fan speed?

But i am totally lost with it because im a new user to Ubuntu when i arrive to that page i see these

• lucid (utils): utilities to read temperature/voltage/fan sensors 1:3.1.2-2: all
• precise (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.1-2ubuntu1: all
• quantal (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.1-2ubuntu2: all
• raring (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.2-2ubuntu1: all
• saucy (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.3-1ubuntu1: all
• trusty (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.3-1ubuntu1: all

So what is lucid? trusty? saucy? and other? i thought its some kind if a ubuntu type (sorry for beeing silly here) i checked my ubuntu version it just says Ubuntu 12.10

So which one i need to download? I saw there are terminal commands, im new to that too, will it cause some problem if i just copy and paste?

PS:

I saw my graphics card is undetected as well i have a ATI Mobility radeon HD 3200, could that cause the problem too?
