Screenshots – Configure Keyboard Shortcuts For Backtrack Linux

Since I write a lot of articles about Backtrack Linux it is nice to have keyboard shortcuts for different screenshot commands. The two screenshot commands that I use most in Backtrack are “gnome-screenshot -w” and “gnome-screenshot”. The gnome-screenshot command will take a screenshot of the entire desktop while “gnome-screenshot -w” will take a screenshot of the active window only. Below I describe setting up  keyboard shortcuts for each of these commands on Backtrack Linux. The below information will work the same on Ubuntu 10.04 as it does on Backtrack Linux since that is what the current Backtrack Linux version (Backtrack 5 release 3) is built on.

To do this follow the steps below so each time your computer reboots you can have the splash screen of your choice. Do keep in mind that if the kernel is updated you may have to follow these instructions again.

dpkg: error processing likewise-open (–configure), Join Linux Server To Windows Domain Controller

In the past I have used likewise-open to join Linux servers to a Windows domain controller. There were always at least some issues using likewise-open and even though it was always possible to get it working it was always a pain. Today I started the process and of course ran into an error which is noted below in more detail so I did some research and came across centrify which ended up being much easier and worked without issue. Use the instructions below to install, configure, and use centrify to join a Linux server to a Windows DC.

Ubuntu 10.04: Disable popup description on mouse hover

Although Ubuntu is a fantastic Linux distribution they have done quite a few annoying things by default in a effort to create a more user friendly work environment. One of these things is the tool tips and descriptions which pop up whenever the mouse is hovered over anything.  This happens for links, applications, folders and pretty much everything else. Its seriously annoying for a seasoned Linux user so I embarked on a quest to disable it. Fortunately its very easy.

Ubuntu 10.4 eth0 – not available! – RTL-8139/8139C/8139C+ (rev 10)

I had a customer today who brought in a laptop and wanted to switch over to Ubuntu linux. I always try to go the extra mile for people who want to convert to Linux. After installing Ubuntu 10.04 LTS, I rebooted and to my dismay the wired (eth0) interface was not working. I always run into wireless problems with Linux but its pretty rare that a wired interface doesn’t work. Below I show the fairly simple fix.
