Testing the new release of Ubuntu I found some changes that don't like very much. First of them is that now the sortcut Ctrl+Alt+BackSpace is deactivated by default, the other one is that the update manager just appear when there are some new update instead of the old icon in the systray. I really hate windows that appear out of control in my desktop.
Fortunately, looking for Internet I could find a solution. In the first case it's enough to add this lines at the end of /etc/X11/xorg.cong file:
Option "DontZap" "False"
To avoid that update manager appears whenever it likes just type this in a terminal:
gconftool -s --type bool /apps/update-notifier/auto_launch false
I have also some problem with the 3D acceleration of my card, a Intel 945GM, that was fixed downgrading the driver to the intrepid version. For that, I added these lines to /etc/apt/sources.list:
deb http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
apt-get update and
sudo apt-get install xserver-xorg-video-intel.
The moral of the post is that Human Beings are prisoners of our habits.
