Add broadcom wireless support in Ubuntu

When you install, or upgrade to, Ubuntu 11.04 you may notice that you can not use your Broadcom Wireless adapter. Many people have left Ubuntu and/or Linux for this reason. Yes, you can look online for a way to install the driver, but I’m going to show you how to quickly install the driver. The way I’m going to show you works in all Ubuntu derivatives.

First, open a Terminal, and enter:
sudo apt-get firmware-b43-installer

It will ask you for your password which you should enter. When the program has been successfully installed go back to your terminal and type in:
sudo apt-get install b43-fwcutter

Again, typing in your password.If you don’t wont to use the terminal you can open your package manager and search for bcm. Make sure you uninstall the bcmw1-
kernal-source package. Search for firmware-b43-installer and install
it, then search for b43-fwcutter and install that. Your wireless should
now work.. Remember, you need to have a wired network connection to do the
steps above!

Open K-menu on Window key press event

Many KDE-users want to open their K-menu(default right side menu bar) when windows key(super key) is pressed.

Here is the best solution.

Steps:

1. Find the scancode for SuperKey. Open a terminal and type:
   xev
   
2. Press your SuperKey (Windows Key) and watch the scan code returned (mine is 133)
3. Map that scan code to a 'phantom key (F13)' With this test--type:
   
xmodmap -e "keycode 133=F13"

   You should get returned to a prompt with no message. Then, right-click on the KDE menu, choose Launcher Settings, Keyboard Shortcut, then click the wrench symbol. Press your SuperKey and F13 should appear. Click Apply.
   Test the menu by pressing the SuperKey--it should now appear.
   
4. Automatically create mapping on startup If the above worked, you now need to automate the key mapping on each startup. From the terminal window type:
   
cat << EOT >> ~/.kde/Autostart/xmod.sh
#!/bin/bash
xmodmap -e "keycode 133=F13"
EOT

sudo chmod 755 ~/.kde/Autostart/xmod.sh

   Thats it..Bingo...You are KDE-Power-User..
