No cursor in Ubuntu linux 11.10

-
I've had this weird problem lately on Ubuntu 11.10 (64 bit) - I only seem to have a cursor in some windows and never in any of the system windows (desktop, unity bar etc). Well today it was winding me up so I decided to try and fix it

A quick google got me this page: No Cursor in Ubuntu 11.04 with a Legacy Nvidia Card. Not the right version of Ubuntu I know, and I have no idea what video card I have either, as the system info shows it as 'unknown'. But I figured I'd try it anyway

Steps from that page:
1. Open a terminal window 2.
Stop the x server: sudo service gdm stop
3 Uninstall the nouveau driver: sudo apt-get --purge remove xserver-xorg-video-nouveau
4. Reboot the machine

When I got the step 2 though, it said the gdm service wasn't found, so I just did step 3. This unfortunately stopped the cursor moving at all! So I reinstalled the nouveau driver, and now it works! Now idea why!

So for anyone who needs this, my steps were:

1. Open a terminal window
2 Uninstall the nouveau driver: sudo apt-get --purge remove xserver-xorg-video-nouveau
3. Reinstall the nouveau driver: sudo apt-get install xserver-xorg-video-nouveau

And all was well with the world again :)

Launch a website as a mobile app using PhoneGap/Apache Cordova

How to launch a website as a mobile app using PhoneGap/Apache Cordova I spent some time recently trying to find out how to launch my website as a mobile app.  The information was available around the internet but since it took me a while, I thought I'd collate it here in one simple post for anyone who wants to do the same I decided to use Apache Cordova since it gave me the framework for developing an HTML5 site as a mobile app already, meaning all I really needed to do was plug my website into it.  Their getting started guide has good information on how to create a Cordova project - I used Android but you can use whatever means you wish A basic Cordova app gives you a way to launch the app with an HTML page that you use to display your app contents.  The trick then is make the page load your website which you can do in one of 3 ways: 1. Package your site inside the app. This means it loads fast and without an internet connection.  The downside is you have to update and

Installing and using mobilize.js to transform a desktop site to a mobile site

Installing and using mobilize.js to transform a desktop site to a mobile site mobilize.js offers a neat and simple method of creating a mobile optimised website with very little change to the main desktop site. With a few lines of javascript and some css you can create a mobile optimised site without having to maintain 2 different sets of content. However the instructions on the official site aren't the best. So with some digging I managed to transform - From this (Firefox on my laptop): To this (Android browser on my Samsung Galaxy Nexus): with no html changes other than adding some <script> tags to the <head> element.  Plus automatic browser detection to display either site depending on the browser used - mobile, or desktop Here are some step-by-step instructions on getting it working. Why would you want to? So going back to the beginning, these were my requirements:  I wanted to create a mobile optimised site but, as I already had a

How to manually add Cordova plugins to your app

-
I have recently been trying to add a plugin to an existing Cordova app (using Cordova 3.7.0).  Since I didn't create my app using the CLI I had 2 options: Create a new app using the CLI and copy my source files over Add the plugin files to my existing app For some reason I don't really like the idea of the CLI and wanted to do do this manually into an existing Android app, using Cordova, rather than use the CLI.  Don't ask me why, I just like doing things manually so I know what's going on under-the-hood I guess If you are like me and want to add a plugin manually, this is how to do it.  These instructions, though written for Android, will work for any any supported platform.  I will call out any differences between platforms that I know of Get the plugin source files You need the source code files for your platform (so .java for Android, .m .h for iPhone etc) as well as the plugin javascript files.  You might be able to get the source files from the inte
