Lenovo3000N100_FPG

Clear message

This is the LaptopTestingTeam page for the Lenovo 3000 N100 FPG. The Lenovo website lists [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-48NT8D laptops which are compatible] with various Linux distros (Suse, Novell, Red Hat, Turbolinux). The N100 has only been tested on the last two.

This laptop worked out of the box under feisty - except for fixing the screen resolution, updating the sound drivers and turning on the microphone capture.

Screen

If you're using Feisty you can use the xserver-xorg-video-intel (universe) package to make this work:

{{{sudo aptitude install xserver-xorg-video-intel }}}

Ohterwise, you must install the package 915resolution (universe) in order to get the native 1280x800 resolution. Nothing else to configure, just install it and restart the X server (logout/login or Ctrl-Alt-Backspace).

{{{sudo aptitude install 915resolution }}}

However, using both solutions I keep having a slow refresh rate which is sometimes visible in the background as wobbly lines (it especially shows on the orange standard background). Actually - Vista (which comes with this laptop) has the same problem out of the box, though their driver may autoupdate (not verified). --KlaasVanSchelven

Sound

Under Feisty, sound does not work out of the box, and still does not work including updates until the 3rd July 2007.

I used the ["LaptopTestingTeam/Lenovo3000C200_89224MG"] page to get sound working. This section is basically a rip-off from that page. As of the 4th of July this page is more recent, however.

Note: If you would rather not recompile ALSA yourself, however, none of the internet provided packages like provided on the ["LaptopTestingTeam/Lenovo3000C200_89224MG"] page worked on my machine.

So, you'll need to install a few necessary build tools. Summary: Download the latest alsa-rc driver,lib and utils source, compile and install the alsa packages, insert the new module et voila!

This is intended as a copy & paste howto. You have to use Shift+Insert to paste into the Terminal.

To start install some required build tools, open up a terminal (Accessories>Terminal) and: {{{sudo apt-get install build-essential ncurses-dev gettext }}} and then: {{{sudo apt-get install linux-headers-uname -r }}}

Now we need to download the alsa packages. Make a temporary directory in your home directory: {{{cd ~ mkdir alsa-src cd alsa-src wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.14.tar.bz2 wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.14.tar.bz2 wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.14.tar.bz2 }}}

Extract the tars: 

tar xvf alsa-driver-1.0.14.tar.bz2
tar xvf alsa-lib-1.0.14.tar.bz2
tar xvf alsa-utils-1.0.14.tar.bz2

It's best to stop alsa at this point.:

{{{sudo /etc/init.d/alsa-utils stop }}} Or {{{sudo /etc/init.d/alsasound stop }}}

Now we can compile the alsa packages: {{{cd alsa-driver-1.0.14 ./configure --with-cards=hda-intel make sudo make install

cd ../alsa-lib-1.0.14 ./configure sudo make install

cd ../alsa-utils-1.0.14 ./configure sudo make install}}}

Now we remove the old and insert the new alsa module: {{{sudo modprobe -r snd-hda-intel && sudo modprobe snd-hda-intel }}}

Note: If you get a message saying "FATAL: Module snd-hda-intel in use" be sure that the Alsa driver has been stopped (see above).

You should now have working speakers!

One final tweak I had to do to get recording working as expected was to open up the gnome volume control/mixer. Go to edit>preferences and tick the input source track to be visible. This gives a new tab called options on the mixer where it is possible to choose the record source. Frontmic is for the internal mic, Mic for the external input, Line isn't used (will be removed in next patch) and CD is for...thats right cd.

Microphone Capture

However, after fixing the sound, the microphone capture does not work. (neither front nor plugged in one). Both can be heard when turning on Unmute but cannot be used for recording.

Start alsamixer from prompt: alsamixer Use tab and arrow keys to end up at capture and then hit spacebar to turn capturing on.
