Stupid Ubuntu tricks: 5 Steps for resetting a forgotten password

GRUB

It happens to everyone. You have so many usernames and passwords that you can't remember them all. Fortunately, Facebook, Gmail, and about a billion other online services have a "forgot password" link. Just click it and the web service will either email your password to you or allow you to reset it and enter a new one.

But what happens when you forget the password for your operating system. Not that this has ever happened to us, but hypothetically let's say we were trying to perform a fresh install of Ubuntu on a laptop this afternoon. We zipped through the installation screens so quickly that we may have accidentally inclued a typo in our password. So when the installation was complete, our (still hypothetical) computer booted up, loaded a splash screen, and then wouldn't let us login no matter how many variations of our password we type.

While you might think the easiest thing to do is reinstall Ubuntu, (after all, this is a clean install so it's not like we'd be losing any data on our hypothetical system), you can save yourself 15-30 minutes by changing the password. It turns out you don't have login to change your password. As we discovered thanks to a useful post on the Ubuntu forums, you can do it from the bootloader screen. Check out the 5 easy steps after the jump.

QGRUBEditor grows up and becomes KGRUBEditor


Setting up a dual boot system that can run Windows and Linux is relatively painless. Many newer Linux distributions like Ubuntu make it easy by automatically detecting any hard disk partitions with Windows installed and setting up GRUB, a boot manager that lets you choose between operating systems when your computer starts up.

But editing GRUB can be a pain in the behind unless you know what you're doing. If you want to change priorities, so that Windows boots by default, for example, you need to find the menu.lst file, edit it as an administrator, and hope that you haven't messed anything up that will prevent you from logging into either operating system on your next boot.

A few months back we looked at QGRUBEditor, a utility that takes much of the pain out of editing your GRUB settings. QGRUBEditor is available for Ubuntu, SUSE, Slackware, Gentoo Linux, and the source is available for anyone who wants to compile it on another operating system. But development on QGRUBEditor has ceased, and a new application called KGRUBEditor has been released.

KGRUBEditor has all the features of QGRUBEditor, but it's built using KDE4 libraries. And it adds a few new features like an easier to use interface, and a color preview window that shows what the GRUB menu will actually look like when you boot your computer.

Because KGRUBEditor is KDE-based, you'll need to install a ton of prerequisites to get the application to work on a system that's not already KDE-based. So if you're buntu of choice is Ubuntu and not Kubuntu, you might want to stick with QGRUBEditor for now.

Manage your GRUB menu the easy way with QGRUBEditor

QGRUBEditorUbuntu and Kubuntu have become a world wide phenomenon. Nearly synonymous with the word Linux, it has become the Operating System of choice for hundreds of thousands of people and organizations. This success is partly owed to the simplicity of the system. Insert the Live CD, install, and everything else is automatic.

However, when the user wishes to make changes to the system, Ubuntu and its cousins tend to be a bit less convenient. Under normal circumstances, the user must crack open that dreaded Terminal and edit settings by hand.

This is where QGRUBEditor comes in. With its simple and self-explanatory GUI, this application helps configure every aspect of the GRUB boot menu.

QGRUBEditor
is free, Open Source, and just an APT-GET away for Ubuntu users. It's also available for SuSE, Arch, and Slackware.

How to install 145 operating systems on one PC

Grub
So you think you're pretty hot because you figured out how to load Windows XP and Ubuntu on your PC, huh? Or maybe you've even gone so far as creating a triple boot machine with XP, Vista, and a Linux distribution. Well, one JustLinux forum member has you beat. And by beat, we mean he finished a marathon in the amount of time it took you to cross the street.

JustLinux member saikee has posted details of his system that boots 145 operating systems. That includes 3 versions of DOS, 5 versions of Windows, and 137 flavors of Linux. He created 152 partitions on 4 hard drives to get his system up and running. And he probably has the longest GRUB menu you've ever seen. We're guessing the slowest part of the boot process on this system is the amount of time it takes to find the operating system you want to use.

There are obviously very few practical reasons anyone would want to load 145 operating systems onto a PC, but we have to say, we're pretty impressed anyway. It's kind of like climbing Mount Everest because it's there. If you had licenses for 8 MS operating systems, the ability to download as many Linux distributions as you'd like and way too much free time on your hands, wouldn't you do the same thing? No? Oh, well, nevermind then.

The World's Hardest Game 2.0 - Time Waster

So, just how good at time waster games are you? Think you've got the stuff? Well, The World's Hardest Game 2.0 doesn't think you do. Yes, amazingly, it's possible to have a sequel to a game called "The World's Hardest Game". It doesn't seem logically possible, since if the first one was actually the world's hardest, how could another one come along and share the moniker? It made me doubt the name in the first place. That is, until I tried the game. The mechanics of the game are very simple. You are a small red square, ...
