Rebuilding the VirtualBox Kernel Modules (Ubuntu 9.04)

Any time there is a kernel update, you would do well to rebuild the VirtualBox kernel module to ensure compatibility with your new kernel version. This can be done by executing the following command from the terminal:

sudo /etc/init.d/vboxdrv setup

Installing Fonts in Linux (Ubuntu 9.04)

First, you can find some good free font downloads at http://www.sostars.com.  I downloaded a stencil font called "Ver Army." I unzipped the file, and found a .ttf font file.

I learned how it install it from this page. Here's a summary:

To install Microsoft Windows fonts: sudo apt-get install ttf-mscorefonts-installer
To install Red Hat Liberation fonts: sudo apt-get install ttf-liberation

To install any other kind of font (including the one I downloaded from sostars.com):

1. 
   mkdir ~/.fonts (make a font directory in your home directory if one doesn't exist already)



2. 
   mv ver-army.ttf ~/.fonts (move your ttf file into the .fonts folder)



3. Restart the computer
