Habe das Script gefunden und bisher nicht getestet.
This script will install everything for you: Beep-Media-Player, a Beep-Media-Player skin, aMSN, an aMSN skin, fix the CD-ROM eject problem, auto-install autologin, install IceWM, remove the system beep, install codecs, install special settings, install prelink/preload, install Flash/Java, install Ivman, set up giFT, install fonts, install extra archive support, install search with Thunar, install Opera and set it up with Xubuntu, install dash, update Xarchiver….if it can be done, it’s done. Things I’m missing are original Firefox and Thunderbird icons, extra Beep-Media-Player plugins, and perhaps tweaking xorg.conf, adding Xarchiver thunar-archive-plugin support and stopping Thunar from loading twice.
