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
waste utilize some free time fixing it.
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?
For a long time the restart X shortcut was:
Ctrl + Alt + Backspace
This helped many people out of a bad spot. Graphic capabilities were limited in them days and hang ups were more common. Hardware and Linux distributions have improved since and become more stable since then.
Since Ubuntu 10.04 this was changed to the lesser known shortcut:
Alt + PrtScr/SysReq + K
As “Gtk-WARNING Default font does not have a positive size” suggests, this arises from a font size specified incorrectly, or not at all in some cases. This problem annoyed me for a while after using a few different window managers with Linux (Ubuntu in particular). I believe it came about after changing some font settings and changing themes a few times, particularly with LXappearance. I’m guessing if you are looking at this you have also made a few changes and are now also being annoyed by this message!
You will see this annoying message, repeated numerous times in the terminal, when launching applications from a terminal:
Gtk-WARNING **: Default font does not have a positive size
