Re-install ubuntu-desktop metapackage and reinstall its dependencies

Ubuntu-desktop is a meta-package in ubuntu that connects all the packages that are installed by default in a fresh ubuntu install. For that reason you can remove it without any damage to other packages or your system. It can be automatically removed if you remove ekiga or gnome-games.

But what if at some point you want to revert all the changes so you have the default packages reinstalled again?

Running :

sudo apt-get install --reinstall ubuntu-desktop

does not reinstall its dependencies. So the solution is :

sudo apt-cache depends ubuntu-desktop | awk -F ":" '{print $2}' | \
sed '/^$/d' | xargs sudo apt-get \
install --reinstall --install-recommends --yes

(yes this is one line :))

fix firefox 3.5 crash with full-screen flash

This is an annoying nvidia bug with the latest Firefox (Shiretoko) version 3.5.
To fix it you need to load the flash plugin before firefox.
To do this you have to find the firefox startup script (mine is in /usr/lib/firefox-3.5.1/firefox.sh) and add the following line at the beginning of it (be careful to not wipe the “#!/bin/sh” line!):

export LD_PRELOAD=/usr/lib/libGL.so.1

Now you can have full-screen videos again in youtube ;)

this is an easy way to download multiple file (batch download) from anywhere including rapidshare with or without premium accounts using command line.

Create a file named “down.txt” and paste the rapidshare links there, one link per line.

Next create a bash file named “multidown” and paste the following in it, replacing the “YourUsername” and “YourPassword” with your data :

#!/bin/bash
for i in $(cat down.txt); do
wget   -nc  --user=YourUsername  --password=YourPassword "$i"

then alter permissions for this fileto make it executable

chmod u+x multidown

and run it

./multidown

or you can also put a launcher in your desktop ;)

Important : you need master git for both plugins to work !!

Master git is the latest version of compiz.

If you are looking for a way to install compiz fusion from git take a look at this (look at Makefusion script)

Note : if you are going to use makefusion script to install compiz then you don’t need this , as both plugins are already in plugins-extra category
