Setting a static IP in Ubuntu is useful for a lot of things. You may want to forward ports from your router to serve web pages, use SSH from outside your local network or set up some sort of media server.
The UUID of a Linux partition is the Universally Unique IDentifier of that partition. I would say with a fair bit of confidence that in this and most scenarios, the Linux partition UUID has more of a local machine scope.
Ignoring broken packages in Ubuntu or any other distribution of Linux using Aptitude package manager would usually be a bad thing and it’s not recommended. Maintaining a system of broken packages kind of defeats the object.
BUT, I recently came across a situation where I had to install a 32bit version of Chrome on my 64bit Ubuntu.
I recently updated my home machine to Ubuntu 12.04 and found MySQL 5.5 installed as default. As happy as I was to have the latest stable MySQL server, I was a bit gutted to find that LOAD DATA LOCAL was disabled as default, due to security issues. These issues may be valid but this is my local environment and I’ve got projects that require it so thought I’d

Install LAMP Server on Ubuntu?
A few complex packages but all (bar linux!) can be installed with one command and then following the on-screen instructions:
(NOTE: All the commands here need to be typed into a terminal, open one by pressing Ctrl+Alt+T.)
This is a problem that could come across quite often. How to replace text in multiple files at once?
If you are running a UNIX system you are lucky: with a simple BASH script you can achieve this.
I recently posted an answer on askubuntu regarding the LightDM resolution settings. I thought it would be best to bring it over here and maybe explain things a bit better.
Dual monitor settings in Ubuntu are clumsy at best. I have tried set ups on numerous machines and I find the most reliable method is to change the monitors.xml file. For more information on monitors.xml, check out the Ubuntu Wiki on Resolutions.
Sometimes in you find yourself in the middle of a graphical meltdown, all of a sudden the restart X shortcut for Ubuntu is your best friend! Otherwise you find yourself trying to drop out of graphical mode into a terminal user. Or heading straight for the power button!
So, what is the restart X shortcut for Ubuntu?

Since Ubuntu 10.04 this was changed to the lesser known shortcut:
Alt + PrtScr/SysReq + K
