anyone can guide me what should I do?

You are aware that 9.04 is 'end of life'/out of support for over a year now (EOL was 23-10-2010)?

https://wiki.ubuntu.com/Releases

You'd be better off getting a newer version (or a different distro) IMO.

BTW, check up about 'unity' before you go getting the newest version of ubuntu. If you want to have gnome 2.X ('classic gnome') then dont go to 11.10.

Thank you cascade9

Btw, I don't feel like upgrade my ubuntu yet. Do I have any other option to fix my current problem?

Thanks.
