Old Kernel Images
May 28th
After an update to a new kernel image you can remove old kernel images with synaptic package manager. Just give a search for “linux-image”, and uncheck your old kernel images. Then in a terminal type “sudo update-grub” to remove the old images from your grub boot menu.
Change of Kernel Requires Reinstall of Modules
May 27th
Any program that utilizes a Kernel Module will require re-installation after upgrading to a new kernel. For instance, my experience is with NDISWrapper and VirtualBox as both utilize Kernel Modules.
Beryl Window Manager Bypass
May 26th
For some reason compiz does not work on my system; I get the dreaded white screen of death. Beryl does work tho. One time I click the compiz window manager and got the white screen of death and had to do the following to rectify the situation: I had to boot in recovery mode, and since beryl-manager was set as a session to boot on startup I had to remove beryl-manager sudo apt-get remove beryl-manager Then I re-booted normally. Then open a terminal and type: sudo apt-get install beryl-manager beryl-manager –no-force-window-manager This will start beryl-manager, and put the diamond on your task bar, but not load the window manager. Then I simply selected metacity or beryl. Since beryl does was compiz does, but has more options, there is no reason for me to select compiz as the window manager.
Wireless Lan and NDISWrapper
May 25th
First you need the files to compile ndiswrapper: user@ubuntu:~$ sudo apt-get update user@ubuntu:~$ sudo apt-get install build-essential user@ubuntu:~$ sudo apt-get install linux-headers-`uname -r` user@ubuntu:~$ sudo ln -s /usr/src/linux-`uname -r` /lib/modules/`uname -r`/build Then download the latest and greatest NDISWrapper version. http://sourceforge.net/project/showfiles.php?group_id=93482 Unzip the download. Then type: make uninstall make make install Then you need your windows driver. The bcmwl5 driver is popular and applicable to many cards due to the popularity of the Broadcom chipset. Download your WIndows driver from the manufacturer of your computer. All computer manufacturers provide the drivers on their websites. Since the drivers are typically in .exe files, you will need cabextract; to install type this: sudo apt-get install cabextract Then use cabextract to unzip the .exe file with the drivers: cabextract drivers4830.exe The files will then be unzipped. Then install the driver: sudo ndiswrapper -i bcmwl5.inf Then load edit your iftab file to make sure NDISWrapper can use the card: sudo gedit /etc/iftab   ;   make sure that there is nothing that references wlan0 (use # to comment) Then simply load the NDISWrapper module: sudo modprobe ndiswrapper Make sure the switch for your wireless is on. Your network manager should automatically show available networks. If not go to System-Administration-Network and make sure the wireless card is configured to “roaming”. BAM, easy as pie.

Windows is not Needed as the Boot OS
May 18th
Linux is far superior to any version of Windows due to stability, 3d Desktop Effects, and other little tidbits. There is no substantial reason to retain a windows boot partition given the function of VirtualBox. A Virtual Windows intallation operates the exact same way as if it was on a boot partition, except you can minimize Windows just like any other window. VirtualBox provides incredible versatility to utilize certain Windows applications that are not available in Linux, all while having Linux as your primary OS!!!
