I’ve been playing with Kubuntu Intrepid (8.10) for about two weeks and the thing that annoys me most is the autocomplete option in Konsole/shell.
so, if U want to enable it, do following:
sudo nano /etc/bash.bash.rc -> uncomment part # enable bash completion in interactive shells
source /etc/profile
everything should work now 
edit and copy-paste at the end of the file /etc/sysctl.conf

having problems with playing matroska codec on your dvd/divx player? convert it simply to something readable
user@machine:~/Videos$ aptitude install ffmpeg libmatroska0 mkvtoolnix mkvtoolnix-gui
user@machine:~/Videos$ mkvmerge -i movie.mkv
File ’s-300.mkv’: container: Matroska
Track ID 1: video (V_MPEG4/ISO/AVC)
Track ID 2: audio (A_AC3)
user@machine:~/Videos$ mkvextract tracks movie.mkv 1:movie.mpeg4 2:sound.ac3
Then, use k3b to burn extracted files as DVD.
