Backporting

A good guide to backporting is at

  https://raphaelhertzog.com/2010/12/15/howto-to-rebuild-debian-packages/

A deb-src line in sources.list for unstable is needed to do:

 apt-get source libsane-common/unstable

Then:

 apt-get build-deps libsane-common/unstable

should get the dependencies from stable to build libsane-common and libsane.

firefox custom alternatives

update-alternatives --install /etc/alternatives/firefox x-www-browser /opt/custom/firefox/firefox 300
update-alternatives --set x-www-browser /opt/custom/firefox/firefox

Configurations

Some notes on kernel configuration options (linux 3.3.8) with some notes about intel splash on a intel chipset notebook. Most of the following is a server setup on AMD though.

CPU Frequency

Set min / max values

create file if not existing

/etc/default/cpufrequtils

define min/max value and governor

GOVERNOR="ondemand"
MAX_SPEED="3.6GHz"
MIN_SPEED="1.4GHz"
