With the new release of Ubuntu, Karmic, it seemed that the audio on HP notebook DV6, equipped with Intel HDA sound card, had been settled .. In fact, the comments to my previous post ( "Karmic Koala HP DV6-1205sl: first impressions"), is not exactly so .. It seems that even manually resetting the volume of PC speaker, you are unable to use the headphones .. Personally I updated Alsa, that does not solve the problem permanently, but if no other limits. Besides, I think cmq useful to be able to perform a manual update, which explains this guide.

First step, prepare the system:

sudo apt-get -y install build-essential ncurses-dev gettext xmlto
sudo apt-get -y install linux-headers-`uname -r`

Step two, download the source into a directory created on purpose

mkdir -p /home/alsa-driver
cd /home/alsa-driver

wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.21.tar.bz2
wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.21.tar.bz2
wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.21.tar.bz2

NB There would also be downloaded alsa-firmware but on the official website of the project (Alsa-project) is still at version 1.0.20, which is already present in Karmic, so I preferred to skip this file ..

Now Unzip the three files downloaded:

tar xjf alsa-driver*
tar xjf alsa-lib*
tar xjf alsa-utils*

Third step, compile the source obtained:

cd alsa-driver*
./configure --with-cards=hda-intel --with-kernel=/usr/src/linux-headers-$(uname -r)
make
sudo make install

cd .. / alsa-lib *
. / configure
make
sudo make install

cd .. / alsa-utils *
. / configure
make
sudo make install

WARNING! During configure you get the error: configure: error: panelw library not found Do not worry, just create the directory where you find the following symlinks:

sudo ln -s libpanelw.so.5 /usr/lib/libpanelw.so
sudo ln -s libformw.so.5 /usr/lib/libformw.so
sudo ln -s libmenuw.so.5 /usr/lib/libmenuw.so
sudo ln -s libncursesw.so.5 /lib/libncursesw.so

At this point, you need to reboot the system (yes, every now serves in Linux! ), And restart to check that everything went well with the command:

cat /proc/asound/version

Which should return as output something like this:

Advanced Linux Sound Architecture Driver Version 1.0.21.
Compiled on Nov 3 2009 for kernel 2.6.31-14-generic (SMP).

Fourth and last step, run the automatic configuration of Alsa, typing in a terminal:

sudo alsaconf

I guess a little bit all those who "hang" open souce, and Debian (and also Ubuntu) knows what he's capable Gimp, well-known image-editing program useful both to create and / or edit images, and as a replacement for Photoshop. Let's see how to install Lenny on our last release, 2.6.6, from source ..

A tip, if you have a previous version already installed (very likely, given that almost always part of the default installation of Debian), remove, for example from Synaptic.

First, make sure you have the source repositories enabled, checking that the file /etc/apt/sources.list there is the line:

deb-src http://ftp.it.debian.org/debian/ lenny main contrib non-free

Then we employed (data are the following commands as root):

apt-get update
apt-get install build-essential
apt-get build-dep gimp
apt-get install libgegl-0.0-dev

At this point we download from here the sources and scompattiamoli:

tar -xjvf gimp-2.6.6.tar.bz2
cd gimp-2.6.6

Finally, we can install (the last command is given as root):

./configure
make
make install

Now you have the executable Gimp 2.6.6 in /usr/local/bin for convenience, you can create a launcher to be placed directly on the desktop ..

AcetoneISO is a software to create images of CD / DVD in Linux, we can read images in various formats, create them, mount them. On the official website are precompiled packages for various distributions, including the. Deb for Ubuntu. Obviously, this pack is good enough for Debian, but can be useful to compile from source, also because the Ubuntu package, as suggested by the authors themselves, not relative to the last released version (2.0.3 RC1 at this moment) . Let's see how to do ..

WARNING: The following is the simple procedure also indicated in the README file inside the source, as was done by myself, do not panic is extremely simple.

First download the source here.

Then ensure that we have the compilers installed:

apt-get install gcc g++ make libqt4-dev

Now install the dependencies:

apt-get install fuseiso fuse-utils libqt4-gui genisoimage cdrdao p7zip-full gnupg-agent gnupg2 pinentry-qt ffmpeg mencoder cdparanoia

Obviously other dependencies installed automatically reported.

Well, at this point we enter the directory where we saved the source and give:

tar zxvf acetoneiso_2.0.3RC1.tar.gz
cd acetoneiso_2.0.3RC1
qmake-qt4
make
make install

The last command is given as root. Done, you've installed AcetoneISO! Now let's change some permissions and add our user to the group fuse (everything must be done as root).

modprobe fuse
chmod 4755 /usr/bin/fusermount
chmod o+rw /dev/fuse
addgroup {nome-utente} fuse

Where instead of {nome-utente} you must enter your user (eg addgroup redblue fuse

Should you uninstall AcetoneISO, just enter the source directory and as root, give:

make uninstall

EDIT: to the undersigned at the end of the installation occurred an error concerning the file AcentoneISO.Desktop, if it happens to you do not worry, this is simply a shortcut on the desktop, the installation was successful, however, you simply create by hand the desktop shortcut (if you need it), for the link in the menu but there is no problem, I was set normally.

Often the "linuxiani" like myself have to deal with installing from source, which may be extremely complicated, but if done with the right methodology, it is extremely satisfying. Sometimes it can be very handy to create a package. Deb to install (or uninstall) then with automated tools like dpkg or Synaptic. For this purpose we use auto-apt and checkinstall: the first track we depend, with the second we create the package. How do I use? First of all install the necessary (as root):

apt-get install auto-apt checkinstall

You may also ask other dependencies, install them. At this point, when we unpacked the sources, instead of the classical. / Configure, make, make install, we give the following sequence:

auto-apt run ./configure
make
checkinstall

Where obviously the last command is given as root. And here we have our program and present the list of installed packages in the system. Little extra trick, you can also decide not to immediately install the program, but only to create the package, the command is as follows:

checkinstall --install=no

And you have yours. Deb ready to be installed.
