Eugene van der Merwe's questions

Some time ago I updated my system to the development release of Ubuntu using these instructions:

https://help.ubuntu.com/10.04/about-ubuntu/C/upgrade.html

"If you would like to install and test the latest development version of Ubuntu before it is released, press Alt+F2, type update-manager -c -d into the box and click Run. If a development release is available, an Update button will appear in the Update Manager. Click it to upgrade to the development version."

However, now my machine is always trying to update to the latest development packages causing randomness that I can't afford. Could someone please tell me how to have Ubuntu STOP updating to the development release?

On my dual screen display I have a Unity Launcher on the left hand screen and also on the right hand screen. Both work perfectly fine.

However, I don't want this second launcher present on my right hand screen. How could I remove this? If it matters, I'm using NVIDIA drivers with a TwinView setup.
