1. Launch a Terminal
2. Type in: sudo apt-get update
   (this will ping all the upgrade mirrors to determine if they are live and what upgrade packages are available)
3. Once completed – type in: sudo apt-get dist-upgrade (this will start pooling down the various packages to do a distribution upgrade. Keep in mind – apt-get update will just do an update within the same distribution).

Note: Ubuntu now has an Update Manager that is available by launching the Unity search function and typing in – Update Manager. This is a GUI method of upgrading. I have had failure with this method personally so recommend using the command line for distribution upgrades for more visibility.

This issue is commonly caused by the screen resolution settings in Ubuntu becoming too high for the actual monitor. This guide is written with the Ubuntu Live CD and version 12.10 in mind.

1. During start-up select your language when prompted.
2. Press F6 (Other Options)
3. At the end of the command line type: vga=791
4. Press Enter

Ubuntu should now boot with a resolution of 1024 by 768 (32bit). Click “here” for a Wikipedia link to other Video display choices.

Note: These instructions are for Ubuntu 12.10. Changing your host name in Ubuntu guide.

This commonly occurs right after an upgrade/update to the operating system.

1. First thing is first – your laptop will probably have a Wireless On & Off feature which is either on the side of the laptop chassis or front usually in the form of a button or switch. If it’s off, turn it on!
2. If the wireless is turned on and you are still getting an issue open a Terminal and type: sudo rfkill unblock wifi
3. Press Enter
4. You should now be able to access the wireless.

If neither of the above work – then the problem most likely is you’re wireless on & off switch and it might need to be rewired to be permanently on.

Note: Be best to be plugged into the Internet (through Ethernet) to make sure latest updates are installed and downloaded while running the install.

_Note: Early 2011/As of 11.04 Ubuntu “folded” the Netbook Edition into the normal installation instead of having it separate. _
