Tools like Firefox, OpenOffice, Nautilus, Gimp etc are excellent and builtin. These tools are installed separately.
1) Ubuntu Tweak http://ubuntu-tweak.com/
The most imporant tool is Ubuntu Tweak, with this useful utility its possible to:
a) Change the look
b) Change the behaviour
c) Install more applications
d) Install newer applications
When I have installed Ubuntu (or Linux Mint or Easy Peasy) this is the first tool I install. It is also the key to install some of the applications mentioned below.
2) Shutter http://shutter-project.org/
Screenshot tool with editing abilities. Its way better than Snagit (a popular windows only product)
– remember to install “libgoo-canvas-perl” to be able to edit images
3) Virtualbox homepage: http://www.virtualbox.org/
Virtaulization made easy. Its way faster than VMWare Workstation and its also well integrated into Ubuntu Desktop.
– Tip: If you want to create blazingly fast Windows XP machines, then remember to install Intel AHCI drivers into guest operating system and switch from IDE to SATA in Virtualbox.
3) Pidgin http://www.pidgin.im/
Even though Empathy is maturing to a better product everyday, I still use Pidgin, because everything just works.
– Tip: install “facebookchat-pidgin” to chat with your facebook friends.
4) VLC http://www.videolan.org/
– Excellent Mediaplayer. I use it watching movies and listening to radio.
5) Chrome browser http://www.google.com/chrome
Faster than firefox, but does not have the same pleothora of plugins. Good as a compliment to firefox
6) FileZilla http://filezilla-project.org/
Supports all protocols (ssh, ftp, ftps, etc)
7) Docky http://do.davebsd.com/wiki/Docky
MacOSx-alike taskbar that goes way beyond. Requires “Window Composing” to be enabled though.
8 ) Krusader http://www.krusader.org/
Im used to Total Commander for Windows, and this is an excellent replacement.
9) Wine http://www.winehq.org/
Useful to run som basic and important Windows applications: for example Lotus Domino Administrator, Notespad++, Wordfinder
