Debian GNU/Linux 5.0 ("lenny") on a Samsung P55-Pro T8100 Sevesh

I have recently bought a new laptop, a Samsung P55-Pro T8100 Sevesh. As I was not able to find an installation report for this model anywhere on the internet I thought writing one myself is a good idea. This way people interested in getting this laptop or installing GNU/Linux on it can get some information.

The article covers both the hardware configuration of the laptop itself, a list of which features of the laptop do work and which don't (do not be afraid, most things work perfectly well out of the box) and finally a short installation report.

First of all, let's have a look at the hardware configuration of this laptop:

  • Intel Core 2 Duo T8100 CPU (2.1 GHz)

  • 2GiB DDR2 RAM (PC2-5300 - 667MHz)

  • Intel GM965 chipset with integrated Intel GMA X3100 graphics adapter

  • 250GiB HDD

  • SXGA+ display with a resolution of 1400x1050

  • Intel PRO/Wireless 3945ABG WiFi adapter

  • Intel 82566MC NIC

  • HD Audio Codec, ALC262 sound adapter

  • AuthenTec AES1600 fingerprint reader

  • Infineon TPM module

  • Ricoh cardbus bridge (RL5c476 II) plus cardreaders and IEEE1394 controller

  • One cardbus (PCMCIA II) and one Express Card/54 slot

Now on to the list of what does and what doesn't work with GNU/Linux.

Intel GMA X3100 graphics adapter

Works out of the box. Full resolution is possible without a hack, VGA out works out of the box in both mirror and extended desktop mode.
NO xorg.conf modifications are needed in this setup, everything works perfectly well with a nearly empty xorg.conf!
The only thing I had to modify was making the virtual display a bit bigger so that extended desktop mode works with an external monitor having a resolution of 1680x1050 pixels.

Intel 82566MC NIC

Works out of the box, no further configuration needed.

Intel PRO/Wireless 3945ABG WiFi adapter

Works with the iwl3945 driver, however, it requires something Intel calls "ucode", a proprietary firmware. Without this piece of firmware the card does not work. If you want to WiFi without the need for proprietary software (the ucode) you will have to go for a USB, PCMCIA or Express Card/54 WiFi adapter.

HD Audio Codec, ALC262 sound adapter

Works out of the box.

AuthenTec AES1600 fingerprint reader

The fingerprint reader is said to be working with fprint, which I did not test yet though. Expect an update sometime soon.

Infineon TPM module

Not tested.


Basically the Debian GNU/Linux 5.0 installation went smoothly using the beta2 netinstaller image. The system booted from cdrom and the installation process worked fine.
After rebooting into the new system however the system froze. No response, nothing. The last message on the screen suggested that the ACPI video module is the problem.
After rebooting using init=/bin/sh as boot argument I modified /etc/modprobe.d/blacklist and added the following line:
blacklist video

This is only a workaround for the real problem. The bug is present in Linux 2.6.25 and Linux 2.6.26. A bug report has been filed (here). I will update this page as soon as the problem has been resolved.

There is another thing which doesn't seem to work. However, this could be (and likely is) related to the broken ACPI video kernel module: adjusting the display brightness.
On AC power the system boots with maximum brightness, which cannot be adjusted. Unplugging the AC adapter lowers the brightness.
When running on battery one can use the "brightness up" key combination to switch to maximum brightness, however, this cannot be undone.


The laptop is not only usable under GNU/Linux but most hardware works, even out of the box. The only real problem is the broken ACPI video module, which hopefully gets fixed soon.
I hope this article helps those who would like to get one of these laptops, but are not sure of its GNU/Linux compatibility, just like I was.


  1. Hi,

    thanks for your hints on how to get around the ACPI problem. I just bought a similar model (P55 pro Pasawa - same hardware but comes with Vista Business pre-installed) and was searching for a solution to that problem on openSuSE 11.0



  2. Hello,
    I am looking to buy this same notebook, because it seems to be the only model left that still has a 4:3 aspect ratio. Unfortunately I can't find any reviews of the laptop online. What I am wondering is, if they put the FN or the Ctrl key in the lower left corner. It annoyed me before on Samsung notebooks that it was the FN kex.


  3. @Sebastien

    The FN key is in the lower left corner, the left CTRL key is right to it.

    Personally I found this annoying with the first Samsung laptopt I bought (Samsung P35), but to be honest, I got used to that quickly.

  4. i guess i will use a key-remapping software to fix that issue.
    here's another thing i'd like to know before i buy a laptop:
    say you rest the machine on your lap or flat on your stomach while lounging on your couch, how much/would that obstruct the ventilation system of the fan on the bottom side?

  5. The ventilation system is on the left side of the laptop. There seems to be air intake on the bottom though. I fear I cannot answer that question as I am not using this laptop that way.

    The only thing I could add is that I am still more than happy with my P55-Pro.
