XV for Ubuntu

I just finished installing XV for Ubuntu. At first, I thought it would just be another package to install--i.e. apt-get install xv--It wasn't. The XV version (xv-3.10a) was a little old but it worked for my purpose.

Installation instructions can be found here - http://www.alexx.net/2012/07/xv-on-ubuntu.html

Remove old Ubuntu kernel versions from /boot

I was starting to run out of room in /boot. Had about 10MB of space left. I have been dabbling with Ubuntu for a couple months and I am still learning a lot of its nuances. Seems to be a stable OS and a lot of utilities are available for it.

Determine current kernel version (do not delete this one)
uname -r

List all the installed kernels on your system
dpkg --list | grep linux-image

Find kernels below your current one and remove each one with the following command. Again, don't remove your current kernel.
sudo apt-get purge linux-image-X.X.X.X-generic

Update grub2
sudo update-grub2

Reboot system
sudo reboot

Remove Delta Search features from Mozilla Firefox

I usually use Chrome to surf the Internet but it does not work well (button issue) with one of the Internet radio stations I wanted to listen to. The station (181.fm) worked well with Firefox though. However, I noticed a pesky problem with my "New tab" option. The "Delta Search" homepage was still there when I selected the "New tab" option, and I could not find an option to delete it via the browser. But I did find this page and my resolution was at the bottom of the page. Here's the URL for Firefox users, http://info.delta-search.com/uninstall/firefox

The page also has instruction links for Chrome and MSIE.
