Removing and/or Cleaning Up Old Kernels

This post shows how to remove (clean up) old kernels. Old kernels (to me) are defined as kernels that are installed on your system but no longer needed/used.

You can use a package manager (such as synaptic) to remove old kernels, simply search for linux-image or linux-headers that are installed and remove them. Also of importance is to note that you should remove old kernels and headers together as one is not useful without the other in most circumstances.

Multiboot Disk Partition Layout

As stated on other pages (re: Fix Broken Bootloader), my primary computer (laptop) has a multiboot setup; a triple boot using Xubuntu, LMDE, and Crunchbang.

I have found two solutions for editing PDFs with open source software; the first (flpsed) allows quick and easy simple edit functionality, while the second (GIMP) allows you to do most anything with a PDF.

dmenu - the lightweight, efficient app launcher

dmenu is a dynamic menu for X, originally designed for dwm. It manages large numbers of user-defined menu items efficiently. - http://tools.suckless.org/dmenu/. Simply put, dmenu is an extremely lightweight, text based application launcher.

Using Boxee To Access Local (pictures, video, music, etc) Media

Boxee has the ability to pull your local media into the Boxee client so you can view Internet and Local media all through Boxee. As you will see from my setup, "local" refers to your files on your Boxee computer or your local network as Boxee can pull content in from network shares as well as the local file system.

Adding Local Media

  • Start Boxee and navigate to the media type (video, audio, picture) you wish to add to Boxee.
