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.
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.
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.
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.
