I INSTALLED 64 VERSION, NO AUDIO, NO VIDEO...

A) You must install software compiled for Linux platform. (usually are .deb packages not exe files, exe files are for dos/Windows)
B) You have already a lot of installable software included into repositories
C) Have you already tried to install software using the usual method of Debian derivated distribution as Ubuntu...?

I thing the online guide is the best resource to read https://help.ubuntu.com/

First please install https://help.ubuntu.com/community/RestrictedFormats

You need to have extra repositories enabled..

Please first enable the universe and multiverse repository:

Open System → Administration → Software sources → [ Tab Ubuntu software ]

enable "Community-maintained Open Source software ( universe )"

Close and confirm the repository reload.

Then open a Terminal from the menu Applications→Accessories→Terminal

Tip: right click with mouse on the terminal title caption and select the item "Always on Top" doing this you will force the terminal window to stay on top of the other windows and you will find very easy to copy single row from this web page into the terminal...

Hi :)

Try working through all of the steps in this guide
https://help.ubuntu.com/community/Medibuntu

But i would recommend keeping the non-free (as in Freedom of Speech rather than free beer) components

Good luck and regards from

In Ubuntu and usually in all Linux distribution viruses are not a real problem...

Hope this helps

Hi MARCOBRA,

thanks for quick response!
i know that there is no virus problem in linux system.
BUT, My friends are using windows, and they fear that my system will act as host for viruses (even though they won't affect my system)

 we use pendrive normally, which is the matter of concern for them....

anyways ur suggestions worked...(not all of them, due to 64b compatibility problem)

with regards,AWIJEET

Yes there were some famous and much-publicised problems with some linux servers and corporate machines accidentally hosting some malware. If you really check these stories you find the machines had not had any updates in the last 6 years. Note that is years not days. I think there were other maintenance problems and stupidity such as SuperUser passwords being totally inadequate - not much of an issue on a home machine but on a server it's a serious breach of company security likely to affect a lot of machines. With such a negligence a Windows machine wouldn't have lasted for many months, let alone years.

For a home machine it's fine to just update every few months but it is much better to keep it more up to date if you can. That's usually more than enough to prevent problems.

Good luck and regards from
Tom :)
