I am new here, can anyone tell me is this site is good for discussing problems?
Yes it is. When I first started out using Linux, I came here a lot. Sometimes you might have to be patient with responses (I know I don't come here as often as I used to), but you will generally find the help you need.
Also, searching through old posts you will find much information that is invaluable.
