I have downloaded Blender 2.45, after unpacking it, tried to run it. Then…nothing! No error, no whatsoever. What could be wrong? I tried it on 2 Ubuntu machines (Feisty), the other one has working NVIDIA graphics driver and the other one has ATI graphic card. Both machines do nothing. Just looking at me blankly 
OK.
Start Blender from a console adding the -d option. It stands for ‘debug’ and will give you a maximum of information.
You’ll get message that blender looked for this or that library and didn’t find it. Seach a name similar to that in Synaptic and install that package.
There should be two or three libraries missing.

I did what you said. Yes, there is this missing library. The error I get was this:
“error while loading shared libraries: libopenal.so.0: cannot open shared object file: No such file or directory”
How can I fix this?
Oops! Don’t bother. Already fixed this error. Thank you IamInnocent.
