Make backlight adjustment work in Ubuntu on the Panasonic CF-R7

I was struggeling with the backlight quite for a while now. But finally I found something which finally works.

First you need git core installed

sudo aptitude install git-core

Next you checkout the module

git clone git://git.myrix.net/pana_acpi

The next step is compiling and loading the module

cd ./pana_acpi
make
make install
modprobe panasonic_acpi

At this point you can already check if the brightness buttons are working.
Next copy ./pana_acpi/acpi/* to /etc/acpi
and restart the acpid daemon.

/etc/init.d/acpid restart

This module should work on all the 7-Series from Panasonic. I only tried it out with my CF-R7.

Convert uif Images in Ubuntu Linux

In my windows ages I was used to make backups in uif format. Sofar I couldn’t find any way to transform these images back from .uif to .iso. For all the people out there who don’t know what uif is:

Universal Image Format(UIF) is a powerful compression image file format for backing up CD/DVD. It is fast, reliable, and has rich set of features which include password-protected, data encryption, MD5 checksum support and much more. UIF can not only contain the complete data of CD/DVD just like ISO image, But UIF also supports backing up multi-session CD/DVD, Audio-CD, VCD, SVCD and DVD-Video.

Before I was always using magicISO in wine or virtualbox. Today I found a great tool to do that right inside ubunt. Just get the tool here and compile it and have fun!
