Additional sharing for conky part which I shared at http://marslert.com/blog/2007/10/02/conky/ .
I was trying to install conky to monitor my laptop process as I found that my firefox keep hogging. The installation is pretty simple and straight forward as any ubuntu users knew 
Unfortunately, I got problem for this installation whereby some MPD error was throwing after I executed conky.
$ conky
Conky: desktop window (12000c1) is subwindow of root window (59)
Conky: window type – override
Conky: drawing to created window (3400001)
Conky: drawing to double buffer
Conky: MPD error: problems getting a response from “localhost” on port 6600 : Connection refusedConky: MPD error: problems getting a response from “localhost” on port 6600 : Connection refused
Conky: MPD error: problems getting a response from “localhost” on port 6600 : Connection refused
Conky: MPD error: problems getting a response from “localhost” on port 6600 : Connection refused
Even though MPD configuration is commented in conky configuration, the error is still throwing. Hmmm, what shall do? Lets install MPD through Synaptic Package Manager to solve problem. Yeah. my conky is rocking now
