As an Android phone user I swear by Tweetdeck for Android. I love the orginazation it provides and the best feature in my opinion is that when you return to the app, you start off exactly in the timeline where you last left off. No scrolling up and down to find which was the last tweet you last read. Tweetdeck for Windows has received countless praise also from around the web.
With the addition of the Chrome Web Store you can now get some Tweetdeck goodness in Ubuntu. As far as I know this should work on other Linux distros but I haven't tried it myself. Tweetdeck also has notifications popups among other options. Honestly if you don't know about Tweetdeck for now, you really should. It's on the Windows, Android, iPhone, iPad, and Chrome (Windows & Linux) so you really don't have reason not to have it.
It's a browser plugin for Chrome/Chromium so give it a try. If you don't like it you can simply just disable it. Get it at TweetDeck.com for Chrome.
