Debian Linux on the Toshiba Portege M200
The Machine Hardware Quickstart
The Toshiba M200 is a convertable TabletPC (ie can be used as a normal laptop, but with a quick flip/turn of the screen it works as a Tablet).
It has a 12″ screen, Pentium M 1.4GHz (centrino) and the main part of it is that the screen has a digitizer builtin (using the included stylus).
My configuration has 512MB memory and a 60GB harddisk.
I am running Ubuntu (7.04) with Linux kernel 2.6.20-15.

but can be used to hold a boot floppy image
|Suspend to ram works||Intel 8×0 sound||Works|
Due the the machine not having any internal CD/DVD drive installation has to be done via USB-floppy or the network. I couldn’t find a working floppy disk (you hardly ever need one, but once you do you can never find one 🙂 so I had to do the install via the network.
If you have a SD card you can boot of the SD slot by copying a floppy-disk image to the sd card (via windows or a USB->SD adaptor) as long as you name it $tosfd00.vfd
I setup a network boot server on another box (a Sun Ultra30 running Debian in my case) by following the instructions at debian.org.
Sadly the standard install images didn’t include the driver for the onboard ethernet so instead I used the debian-installer images. Once I figured this out all went smooth.
Intel Pentium-M 1.4GHz (also known as Intel Centrino)
This works without issue, but to save battery you can enable speedstep so you can change the cpu speed from 600MHz to 1400MHz as needed.
I use a program called Powernowd which slows the CPU down when it is idle, but quickly puts the CPU back up (in 200MHz increments) when the CPU is being stressed.
IDE 60GB 5400rpm. Supports DMA. To get better performance make sure you use hdparm to turn on DMA and unmask the IRQ.
to do this use:
/sbin/hdparm -d1 -u1 -m16 -c3 /dev/hda
Change /dev/hda to /dev/discs/disc0/disc or /dev/sda if needed
768MB as 512MB + 256MB DIMMS
No issues here
The onboard LAN port is an Intel EtherExpress100 and so supported by the e100 or eepro100 modules. I use the e100 module.
The builtin wireless is an Intel PRO/Wireless 2100 (as in all centrino-based machines)
Support for this is now available natively and is provided by the ipw2100 kernel module available from http://ipw2100.sourceforge.net/
The Screen is a 12.1″ LCD supporting resolutions up to 1400×1050.
Mode 1400×1050 runs at a pixelclock of 162.0 MHz, HSync of 82.7 kHz and VRefresh of 75.1 Hz
The onboard GPU is a nVidia GeForce FX Go5200 which was not supported by the opensource ‘nv’ driver in XFree86 4.3 but is now with the ‘nv’ driver in xorg.
Full accelerated 2d/3d support can be provided by the closed-source nVidia driver and ACPI suspend now works with this.
If you can accept the loss of 3D acceleration (which I can put up with mostly) you can grab the driver from XFree86 4.3.99 (to be 4.4) which does work with the GPU.
I use the ‘nvidia’ driver and it now supports XRandR so the screen can be rotated by simply running ‘xrandr -o <orientation>’ where <orientation> is left, right, or normal. My xorg.conf file is here.
If you want the console to be at a higher res (rather than 80×25 chars) you can use the VESA framebuffer driver which is built into most kernels.
To get it running at the screens native res (1400×1050) use vga=840 in your lilo.conf or grubs menu.lst.
The modem is a software modem that works fine with either the intel8x0m driver which is part of ALSA or the sl-modem driver which supports a few more features.
The Digitizer built into the screen is a Serial Wacom tablet on IO port 338.
To get this working I used to have to run but with recent system updates it is no longer needed:
setserial /dev/tts/0 port 0x338 autoconfig
I used to have some problems with the wacom driver when in portrait mode but by using this file and putting it in /usr/X11R6/lib/modules/input replacing the standard one. This has been fixed in upstream now and is no longer needed
There are a bunch of 3 keys that are accessable when the M200 is in tablet mode.
The top one sends ‘Ctrl-Alt-Delete’ (labelled as ‘Lock’ key)
The second one sends ‘Escape’
The bottom one is actually a joystick style key that sends the arrow keys when moved or ‘Enter’ when pressed down.
Since they are all sent as normal keys nothing is needed to get them working.
The only issue here is that when the screen is rotated the arrows go the wrong directions. In order to get them working as rotated keys I run xmodmap as
using this .xmodmaprc sitting in my home directory
The SD-slot doesn’t work and from my web travels is appears that many other laptops have this same problem.
NEW:If you copy a floppy disk image (up to 2.88MB) to a SD card and name it $tosfd00.vfd you can boot off the slot. Can be used for initial installation or as a rescue device
Try my rescue image which boots with support for wireless and wired network, full X server and various recovery apps
You can download it from Here just save it as $tosfd00.vfd to your sd-card
ACPI S3 (suspend-to-ram) works with kernel 2.6.0+ with both the open and closed-source nVidia drivers
The onboard soundcard works as an Intel8x0 card (same as most other intel-based laptops)
My laptop doesn’t have bluetooth but I have been assured by Jens Gustedt that it works if you patch your kernel with the experimental Toshiba_acpi patch and use a recent version of Toshset
