For this First You need to install ndiswrapper, no need for net coz the packages are included in the CD / DVD of Ubuntu just go to System>>Administration>>software sources then uncheck all downloadable from internet, Third party and Update repo’s only select Installable from CD-ROM/DVD. Now open a Add/Remove from Applications>>Add/Remove.. there select all avaliable appliactions in show, now seach for ndis you will see Windows Wireless Drivers select it and click Apply changes it will ask you for the CD insert the CD and it will get installed, now you just have to install the drivers of your card for this open System>>Administration>>Windows Wireless Drivers and install the windows wireless drivers ( bcmwl5.inf for hp6515b bcm4312) now follow these steps, type
sudo -i now you must be as root then type
nano /etc/rc.local the file should read
rmmod ndiswrapper
rmmod ssb
modprobe ndiswrapper
exit 0

all done now just reboot and enjoy your Linux……..

Here i assume that you have not done any of this step before and are doing it for the first time but if that is not the case then this might not work for you.
Ok so first step installation of drivers, there are two steps for this as mentioned in the cchtml wiki one automatic and other manual, for automatic you need to enable the restricted repositories by going to System>>Administration>>Software Sources, and the typing
sudo apt-get update
sudo apt-get install linux-restricted-modules-generic restricted-manager
sudo apt-get install xorg-driver-fglrx
which will install the drivers by downloading them from net, if you dont have the bandwidth to download that much you can go for the manual install where we will build those file, here i assumed that you have copy of the ati drivers .run file which if your Ubuntu is installed by me could be found at “/”, to build we need to install certain packages
sudo apt-get install module-assistant build-essential fakeroot dh-make debhelper debconf libstdc++5 linux-headers-generic dkms
to build the packages type
sudo bash ati-driver-installer-8.443.1-x86.x86_64.run --buildpkg Ubuntu/gutsy
in the directory where you have the ati-driver-installer-8.443.1-x86.x86_64.run file, this is the latest file at the time of writing but you might have a different file this will work with any driver after 8.38, as they have AIGLX support anyway now we need to install the packages made type
sudo dpkg -i xorg-driver-fglrx_8.443.1-1*.deb fglrx-kernel-source_8.443.1-1*.deb fglrx-amdcccle_8.443.1-1*.deb
when you do that you might be asked
Configuration file `/etc/xdg/compiz/compiz-manager'
==> Deleted (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : background this process to examine the situation
The default action is to keep your current version.
*** compiz-manager (Y/I/N/O/D/Z) [default=N] ?
just answer Y to the question and proceed, once this is done you now need to edit the xorg.conf file type (here — is [minus][minus] unlike a big [minus] as it appears to be )
aticonfig --initial
sudo gedit /etc/X11/xorg.conf
and replace
Section "Device"
Identifier "Generic Video Card"
Driver "vesa"
BusID "PCI:1:5:0"
EndSection
WITH
Section "Device"
Identifier "Generic Video Card"
#Driver "vesa"
BusID "PCI:1:5:0"
Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
EndSection now just restart the X server but pressing Ctrl + ALT + Backspace, all done this will give you the Basic 3D effects but who is satisfied with that we need more so we will go for installing Compiz settings manager, for this type
sudo apt-get install compizconfig-settings-manager gcompizthemer subversion
svn ls https://svn.generation.no/emerald-themes
now accept the certificate and fetch the themes by going to System>>Preferances>>Emerald Themes Manager,
to enable 3D effects go to System>>Preferances>>Appearance then Visual Effects select Custom and edit your settings by Preferances
now you are all set to blow everyone up with your Linux box’s 3D effects enjoy

for apt-cacher to work you need to have a apache server installed and the source of apt-cacher which can be downloaded from here just and extract it and follow the following step as root
mv apt-cacher-1.5.3 /usr/share/apt-cacher
here 1.5.3 was the latest package during my writing, then rename apache.conf to /etc/httpd/conf.d/apt-cacher.conf and set the permisions
cd /usr/share/apt-cacher
mv apache.conf /etc/httpd/conf.d/apt-cacher.conf
chmod 644 /etc/httpd/conf.d/apt-cacher.conf
chown root:root /etc/httpd/conf.d/apt-cacher.conf
now just restart apache
/etc/init.d/httpd restart
now rename apt-cacher2 to apt-cacher and move all the .conf files to /etc/apt-cacher/
mv apt-cacher2 apt-cacher
mkdir /etc/apt-cacher
mv *.conf /etc/apt-cacher/
now edit /etc/httpd/conf.d/apt-cacher.conf and edit user and group to apache
gedit /etc/httpd/conf.d/apt-cacher.conf
after doing that run install.pl
./install.pl
now make /var/cache/apt-cacher and /var/log/apt-cacher owned by apache
chown -R apache /var/cache/apt-cacher
chown -R apache /var/log/apt-cacher
all done just goto http://yourip/apt-cacher and every thing should work fine, if it does not then check /var/log/http/error_log for what went wrong and dont forget to forward the port 3142 (default) so that everyone can access it
you can see how to configure it here and since you are on Fedora you will have to modify some steps a little
enjoy
