TuxMobil: Linux on Laptops & Notebooks with Video Ports

The Linux status of the laptop models reported below, is changing and improving. Therefore, if a laptop is reported as "unsupported" you should give it a try. Why is this survey valuable though: To encourage people which want to buy a "working" stated machine (remember: no guarantees) and to collect technical information (what video ports are used) about different models. At ByteSex(http://bytesex.org) you may find neccessary drivers and tools.

Compatibility Check

There are different ways how to detect, which video port is used in your laptop:

from the official specs
from the output of lspci

Annotations

If your laptop doesn't support a video port by itself you may try an according PCMCIA card, for instance the IBM Smart Capture video capture card. A driver is contributed by <oka_at_nanotsu.kobe-u.ac.jp> Koji Okamura(http://www.mickey.ai.kyutech.ac.jp/~ohashi/scc/) . See also this README(ftp://csb.stanford.edu/pub/pcmcia/contrib/README) .

Abbrevations:

NTSC (North America Television Standard C.) - North America (and Japan at a different sub carrier) television standard. The oldest standard at 1954 (-525 line).
PAL (Phase Alternating Line) - European television standard. First used in the UK and Germany in 1967 (625 line).
SECAM (Système Électronique pour Couleur avec Mémoire) - Typical French politically-inspired system - a beast of a signal. Have also seen it referred to as: "Something Essentially Contrary to the American Method" "SEcond Colour Always Magenta!"
ZV (Zoomed Video) - A separate bus for high speed connection of video and audio data to the graphics and sound processor. Reduces CPU load by bypassing it.

Software

dvgrab

dvgrab(http://www.kinodv.org/index_english.html) saves the video data from a digital video (DV) camcorder into an AVI file. It detects NTSC or PAL without command line options.

w3cam

w3cam(http://www.hdk-berlin.de/~rasca/w3cam/) is a small and fast CGI program to retrieve images from a video4linux device. It supports PPM, PNG and JPEG as output format. You can select size, quality, input device (TV, S-Video, etc.) and more.

atitvout

atitvout(http://www.stud.uni-hamburg.de/users/lennart/projects/atitvout/) is a tool for enabling/disabling the TV out connector and switching of TV standards (PAL, NTSC, etc.) of ATI Rage graphics boards from within Linux on IA32. It is especially useful on ATI Rage Mobility boards, which boot up in NTSC mode by default and need to be switched to PAL for use with German TV sets. Radeon and Rage 128 are supported too, but your mileage may vary.

Linux Video Studio

Linux Video Studio(http://ronald.bitfreak.net/) is a GUI written in GTK to capture video from an external source through an MJPEG-compatible CODEC board: the Pinnacle DC10(+), the Iomega Buz, Matrox Marvel G200/G400/G-runner series, and Linux Media Labs 33. It can do simple frame-by-frame editing (add/delete/move/split scenes and scene trimming) on the recorded movies. The resulting movies can be played back to the output of the video-capture device or can be encoded into MPEG movies.
