Want the latest of the latest updated bleeding edge graphic drivers in Ubuntu?
Open /etc/apt/sources.list:
sudo gedit /etc/apt/sources.list
Add these lines at the bottom:
deb http://ppa.launchpad.net/xorg-edgers/ubuntu lucid main deb-src http://ppa.launchpad.net/xorg-edgers/ubuntu lucid main
Update and upgrade:
sudo apt-get update sudo apt-get upgrade
If you don’t use Lucid (Ubuntu 10.04) just change “lucid” to what ever you use, for example ‘karmic’.
Enjoy :)
Having trouble cleaning up space for your Ubuntu installation?
I only have a 4GB SSD drive on my Lenovo S10e netbook, so I have the problem myself. Here are some handy tips for you!
sudo apt-get autoremove
Basically it clears up the ‘/var/cache/apt/archives/’ and ‘/var/cache/apt/archives/partial’ folders
sudo apt-get clean
sudo apt-get autoclean
This will remove unneeded locale files and localized man pages.
sudo apt-get install localepurge
Run it:
localepurge
A window will pop up. There choose your language. I use English, therefor I chose “en”.
Ignore the capitalized ones.
It shows you which packages that have no other packages depending on them.
sudo apt-get install deborphan
Run it:
sudo deborphan | xargs sudo apt-get -y remove --purge
sudo find /var/log -type f -exec rm {} \;
sudo rm -rf /usr/share/doc/*
Check what kernel you are using:
uname -r
Goto System->Administration->Synaptic Package Manager
Search for “Linux” and mark all Linux header/kernel files which you are not currently using for complete removal. Then hit ‘apply’.
I have just a small 4GB SSD drive with my Ubuntu installation on it, and when I was going to upgrade to Ubuntu 10.04 (Lucid), I had to free up some space. Instead of removing all programs that I had installed, I googled and found something neat.
New packages are downloaded to ‘/var/cache/apt/archives’ and by creating a link to another place with more space you will “trick” the upgrader.
I have also a 150GB drive which I have my home folder located in, so I created a folder there to take the heavy upgrading.
sudo su cd /var/cache/apt mv archives archives-original mkdir -p archives/partial mkdir -p /home/<username>/temp/archives ln -s /home/<username>/temp archives upgrade-manager
Restore to default:
rm archives mv archives-original archives rm -r /home/<username>/temp

One thing I love about vim is that it is extreme configurable. I have put together this config with comments for explenation. Be sure to know what thing does before using them.
Just leave a comment of you think I have forgotten something.

Probably old news, but if you didn’t knew here’s a little cool thing in Aptitude :)
echofish@ubuntu:~$ aptitude moo
There are no Easter Eggs in this program.
echofish@ubuntu:~$ aptitude -v moo
There really are no Easter Eggs in this program.
echofish@ubuntu:~$ aptitude -vv moo
Didn't I already tell you that there are no Easter Eggs in this program?
echofish@ubuntu:~$ aptitude -vvv moo
Stop it!
echofish@ubuntu:~$ aptitude -vvvv moo
Okay, okay, if I give you an Easter Egg, will you go away?
echofish@ubuntu:~$ aptitude -vvvvv moo
All right, you win.

What is it? It's an elephant being eaten by a snake, of course.
