Apt-get upgrade "the following packages have been kept back"

Sometimes you get this message when running apt-get upgrade. The solution is simple : just run apt-get install followed by the list of packages returned after the following packages have been kept back message. This works well enough to get rid of any errors.

Using OpenDNS as your default DNS in Debian

What's OpenDNS : http://en.wikipedia.org/wiki/OpenDNS . To use OpenDNS as your default DNS resolution in Debian type the following commands with root privileges:

cp /etc/dhcp/dhclient.conf /etc/dhcp/dhclient.conf.orig
echo -e "\n# Using OpenDNS as your default DNS - http://www.opendns.org" >> /etc/dhcp/dhclient.conf
echo "prepend domain-name-servers 208.67.222.222,208.67.220.220;" >> /etc/dhcp/dhclient.conf
ifdown eth0 && ifup eth0

Pay attention to "Privacy issues, conflicts and Google redirection" on the wikipediapage .

Flash Player "Square" Preview Release

Adobe® Flash® Player "Square" is a preview release that enables native 64-bit support on Linux, Mac OS, and Windows operating systems, as well as enhanced support for Microsoft Internet Explorer 9 beta. That's good news ! 
Download and install the Flash Player "Square" preview release .
First remove nspluginwrapper and flashplayer-mozilla, after that I move libflashplayer.so to ~/.mozilla/plugins ( I compile firefox myself ). Or move it to /usr/lib/firefox/plugins.
Can confirm that it works with less CPU usage !

A Rebuilt libcairo2_1.8.10-4_amd64.deb

To have better font rendering with iceweasel I decided to rebuild libcairo2 according to this page : ...davidturner... It was a great success !
No need to patch libxft2 and libfreetype6.

Installing Nvidia Driver

For a howto read from here on this page : ...NvidiaGraphicsDrivers... By default Debian comes with a stock kernel : uname -r gives me 2.6.32-5-amd64. You will need module-assistant and nvidia-kernel-common : apt-get install module-assistant nvidia-kernel-common . After that you run the following command m-a auto-install nvidia-kernel${VERSION}-source . And that will be all to build the nvidia kernel module !
After that you will need to install the X driver and user-space libraries package : apt-get install nvidia-glx${VERSION} .
I use the same xorg.conf as on my old computer !

Debian Squeeze 64 bit

With space enough on my harddisk after reinstalling Windows 7 I could easily make a new partition and install Debian Squeeze 64 bit.
Get a netinstall image from http://www.debian.org/devel/debian-installer/ and after the first installation of the bare essentials I did a apt-get install xorg kdm kdebase .
( instead of using kdebase you could also use kde-plasma-desktop).
Gnome users : apt-get install xorg gdm gnome-core.
Add the following lines to /etc/apt/apt.conf :

APT::Install-Recommends "0";
APT::Install-Suggests "0";

A New Computer

I recently bought a new computer from a local Aldi supermarket, it's a Medion Akoya E4360D.
For a review have a look at :http://www.pcworld.idg.com.au/review/desktop_pcs/medion/akoya_e4360_d/339292 

It came with Windows 7 Home Premium 32 bit Dutch version, and surprise, surprise, they divided the whole harddisk into four primary partitions, two of which were hidden ( no drive letter assigned ).

So here is what I did : I backupped my activation with ABR ( Activation Backup and Restore ) :http://directedge.us/content/abr-beta-with-windows-7-support  .
I also downloaded a ( legal ) copy of 64 bit Windows 7 English version : http://forum.notebookreview.com/windows-os-software/428068-legal-windows-7-download-links-just-like-vista-before.html ( go down to ISO method ).
After that I could wipe out the whole harddisk and start all over again, making my own partitions !
