[edit] Motion Computing M1400

The Motion Computing M1400 is a so called "Slate" TabletPC. It doesn't have a keyboard attached like normal laptops do.

[edit] Hardware Facts

  • 1024x768 LCD, "ViewAnywhere" (high contrast screen) upgraded.
  • Wacom digitizer built into the display, compatible with pressure sensitive digitizer pens. Very Responsive
  • 1.1GHz Intel(R) Pentium(R) M (ULV) 2MB cache
  • 512MB - 2GB RAM (While the Motherboard will technically support 2GB of RAM, it has only been tested by Motion Computing with a 1.5 GB configuration, therefore that is all they will support.)
  • 60GB Hard disk (20GB Factory default, but can be upgraded to anything 2.5")
  • Intel i855 Chipset
  • Intel i855GM Chipset Graphics Controller
  • Battery life: 4.5 - 6 hours (4hrs with laptop-mode-tools and dimming backlight)
  • Intel 2200 b/g WiFi
  • 2x speakers
  • 2x microphones
  • 1x Microphone connector
  • 1x Headphone connector
  • 2x USB 2.0 ports
  • 1x Firewire port

[edit] Sound

Works out of the box on any recent kernel with ALSA, but besides unmuting the channels and setting volume You have to set-up the 'LineIn Jack' to 'Mixer Output' and turn off the 'External Amplifier' to get an output from the speakers. The driver is i810 and You can put: 

ALSA_CARDS="intel8x0 intel8x0m"

in Your /etc/make.conf to compile only the i8x0 drivers.

[edit] Ethernet

Works out of the box. (8139too driver)

[edit] USB

Works out of the box.

[edit] Wifi

Wifi works fine with the ipw2200 driver.

[edit] PC Card

See this guide.

[edit] Modem

Untested..

[edit] Kernel

The hardware in the M1400 has a quirk and the current kernel versions (now 2.6.18) need a patch to reboot/halt properly (and the lavg is at least 1.0 always so I recommend patching). The patch can be found here

[edit] X11

X works normally with the i810 driver.

A working setup can be generated from the commandline either with (XFree86) 

# Xfree86 -configure

X.org autoconfigure fails with "Missing output drivers. Configuration failed." 

# Xorg -configure

Follow the instructions you see on the commandline to test your configuration. If X works you can copy the generated file to /etc/X11/XF86Config-4 (XFree86 and X.org) or /etc/X11/xorg.conf (X.org only, has priority over the previous file).

[edit] Digitizer Pen

The serial port of the digitizer is automatically detected on kernels after ~2.6.17, and it has /dev/ttyS0 assigned, so you can skip the following serial.conf details in newer kernels.

Simply put the following in your serial.conf and add serial to the default runlevel.

Code: /etc/serial.conf

/dev/ttyS0 port 0x238 irq 4 autoconfig

Now add the following to your X configuration file or use the example config files below:

File: /etc/X11/xorg.conf or /etc/X11/XF86Config-4

Now add the following to your X configuration file or use the example config files below: 

# Here we define the Tablet/Pen devices, you need to
# "emerge linuxwacom" to add the appropriate driver
# ("wacom") to your system.
# The tablet is connected via an internal serial port
# which needs to be initialized with setserial at
# boot time.
# Please "emerge setserial" and add the following line
# to /etc/serial.conf:
# /dev/ttyS0 port 0x0238 irq 4 autoconfig

   Option     "Type"          "cursor"

   Option     "SendCoreEvents"

Follow the instructions as described in the newly added config data.

And add this in your ServerLayout section: 

   InputDevice "stylus" "SendCoreEvents"
   InputDevice "cursor" "SendCoreEvents"

[edit] On the fly Rotation

The x11-drivers/linuxwacom in portage does not support it, but luckily there is a patch and I made a ebuild for handling it. 

emerge gentoolkit-dev
File: /etc/gensync/tabletpc.syncsource

TabletPC Gensync configuration 

 # This id must be unique among all the ids in /etc/gensync/*.syncsource
 id="tabletpc"
 
 # This is a human-readable description of the source
 description="TabletPC Overlay"
 
 # The rsync url
 rsync="rsync://rsync.burazin.net/tabletpc"

Now fetch the ebuilds: 

gensync tabletpc

and install the patched linuwacom 

emerge "=x11-drivers/linuxwacom-0.7.4_p3-r1"

restart X 

/etc/init.d/xdm restart


File: /usr/bin/rotate

and use the following script for rotating 

 #!/bin/bash
 
 STATUS_FILE=~/.rotate-status
 
 function rotate() {
    case "$1" in
        3|right) N=3; T=cw ;;
        1|left) N=1; T=ccw ;;
        2|inverted) N=2; T=half ;;
        0|normal) N=0; T=none ;;
        *)
           echo -e "Useage:\n  $(basename $0) [left|right|inverted|normal]\n\nIf no option is given, rotates the screen 90 degrees to the right.\n";
           exit 1
           ;;
    esac
    xrandr -o $N & \
    xsetwacom set stylus Rotate $T & \
    echo $N > $STATUS_FILE
 }

 if [ "$#" == "0" ]; then
    rotate $(((3+0$(cat $STATUS_FILE 2>/dev/null))%4))
 else
    rotate $1
 fi

[edit] Dimming the backlight

As root: 

echo N > /proc/acpi/video/GRFX/LCD/brightness

Where N is a number between 0 (very dark) and 15 (very bright)

[edit] ACPI

Standby and wakeup works from X: 

# echo -n "standby" > /sys/power/state

The pen stops working when the TabletPC wakes up from standby.

'mem' seems to cause a kernel hang. The 'disk' methode is not tested. There are some handy scripts standby/suspend related available: 

emerge -av hibernate-scripts
nano -w  /etc/hibernate/hibernate.conf

With suspend2-sources and supplied hibernate script everything works fine.

[edit] Battery monitoring

Needs the appropriate modules modprobed, these can be found in /lib/modules/<kernelname>/kernel/drivers/acpi/
