Operating system

Once I had Ubuntu 9.04 installed from a refactoring partition from another Latitude 2100, the following worked out of the box:

  • touchscreen
  • wireless
  • sound
  • bluetooth


  • ubuntu-netbook-remix
  • launchpad
  • dell team


My Latitude 2100 has Ubuntu as its operating system. It is Ubuntu 8.10 and upgrading to Ubuntu 9.04 makes the touchscreen not work as intended. With Ubuntu 8.10 you can calibrate the touchscreen using the command


This is counter-productive with Ubuntu 9.04.


My Latitude 2100 has an Intel WiFi 5100 and I have a LinkSys WAG160N DSL router with firmware V1.00.07. Instead of a version number as it should have according to http://www.linksysbycisco.com/DE/de/support/WAG160N/download, it has "annex B" written.

first attempt

I got wireless working once like this:

  1. update Ubuntu to 9.04
  2. read google, disabled WMM support because dmesg said "wireless event too big"
  3. disable wireless security on the router
  4. verify you can use wireless
  5. enable wireless security WPA-personal (not, as I had it before, wpa-personal2)
  6. verify you can use wireless
  7. re-enable WMM support

however, this stopped working, probably because of the kernel update I had to perform around 2009-07-31.

second attempt


Downloaded .15 firmware from http://www.linksysbycisco.com/DE/de/support/WAG160N/download and installed it.

  • disabled WMM support
  • worked


My Latitude 2100 has an Intel High-Definition Audio 82801G (ICH7 family). It can play sound and it can record sound as long as you plug a microphone in. In the BIOS the "microphone" is enabled. Regarding the internal microphone I am suffering the following issue: https://bugs.launchpad.net/gnome-media/+bug/290543

amixer -c 0 cset iface=MIXER,name="Capture Switch" on

With Ubuntu 9.04 the following stuff works without problems:

dd if=/dev/dsp of=audio.raw; dd if=audio.raw of=/dev/dsp


With the latest 8.10 kernel, the following commands work:

hwinfo --bluetooth
hcitool scan


  • Fight the memory effect of your battery: Press Fn_F2 and the system will not charge the battery if plugged in.
  • Quickly restore the factory delivery state of the system by choosing a special entry in grub
  • Some notebooks forget they should boot from USB once you disconnect the USB disk. This one does not.

My contribution

I contributed a bug report that led to SUSE being able to record sound on this netbook: https://bugzilla.novell.com/show_bug.cgi?id=529467
