Following on from Clint, Christer, and Valent who all detail the first things they do post install on a Linux system.. Here's mine:-
- Enable Medibuntu repository (see their site for details)
sudo wget http://www.medibuntu.org/sources.list.d/intrepid.list --output-document=/etc/apt/sources.list.d/medibuntu.list sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update
- Get the good (*) stuff
sudo apt-get install ubuntu-restricted-extras vlc mplayer w32codecs miro hpodder skype recordmydesktop ardour audacity ffmpeg ssh gnome-do wine dosbox dosemu spectemu-x11
Mostly media stuff like DVD playback, codecs, fonts, Flash and Java get installed with ubuntu-restricted-extras. VLC and MPlayer for when Totem doesn't cut it. Miro and hpodder for downloading my video and audio podcasts. Evil skype for talking to evil friends. Some screencasting and audio & video manipulation tools. SSH for remote access and gnome-do for fast application access.
Finally some fun can be had with wine and various emulators.
- The "optional" (**) stuff
After all that has finished, I might go and get Zattoo for a bit of TV watching, Gitso for providing support, Gwibber for keeping up to date with Twitter and identi.ca, Google Gears for offline Google Docs and finally VirtualBox for running legacy operating systems.
* For some 'good' read 'bad'.
** I always install this lot so it's hardly optional, but it's a little more manual.
