Here at SignalFive we deal with in-progress apps a lot. This usually constitutes sending out an Ad Hoc distribution, or a version of the in-progress app, to various people with varying degrees of technical sophistication. Like anyone else, we had to go through this process a number of times before getting it right. There are a number of tutorials out there, such as this one, that offer some pointers. But ours has pictures, and goes through even more of the process. Ready? Let’s begin. (Note: This deals with Macs only..a Windows version might be coming in the future).

Find your UDID

First things first….Your iPhone/iPod Touch has a Unique Device Identifier. There are ways to find it in one click, but let’s go one step further. Most likely, you have to get this UDID number out to a developer who will then send you the Ad Hoc Distribution. So, let’s make your life easier. Download an app called AdHoc (it’s free)

If you are looking to install the latest NVIDIA driver on your Acer Aspire 5739G running Ubuntu 9.10 Karmic Koala, you will need to do the following:

1. Download the driver

2. Reboot your machine into recovery mode and run

$ sudo sh DRIVER-PACKAGE-NAME.run

3. Reboot, again and run

$ sudo gedit /etc/X11/xorg.conf

add the line:

Option         “ModeValidation” “NoTotalSizeCheck”

to the “Screen” section

Here is what the Screen section of my xorg.conf now looks like:

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "ModeValidation" "NoTotalSizeCheck"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

You should now be able to take full advantage of your graphics card, run Compiz, set up TwinView, etc.
