This is an addendum to the other reports listed at Tuxmobil - Toshiba(/toshiba.html).
Stylus
The "thumb" button of the stylus is the middle mouse button
per default which was changed to the right mouse button with the option
"Button2" set to "3" in the section
InputDevice of the "stylus" type of the
driver wacom.
xstroke(http://xstroke.org) was installed, but has some problems with the autostart feature of the GNOME session manager: sometimes it autostarts, sometimes it does not.
For Gimp2 to become pressure-sensitive on your strokes, you have to open
its settings and choose the input devices (the top level item; in the
german version are two items with the same name). There you can
configure the extended input devices and you can choose any of the three
stylus devices configured in xorg.conf. Set their mode to
"screen" and you can start painting with soft and hard touches
on the screen.
Screen Orientation
Opposed to the configuration of two X-servers running simultaneously
to provide two different orientations, the XRandR extension is
used here to switch. The driver nv from
x.org does not support rotation on-the-fly, so nvidia is
used which has the option "RandRRotation" set to
"true" in the Device section of
/etc/X11/xorg.conf. Another advantage is that you gain
excellent 3D performance, with the downside that Suspend-To-Disk is
broken, when it worked with the old driver. Perhaps it needs more than
two hours to properly configure that beast for suspension.
With that driver, you can use the gnome-randr-applet to change
the orientation. Alas, it was not found out how to change the orientation
of the mouse accordingly. So the touchpad is configured to work correctly
in landscape mode and the stylus to work correctly in portrait mode.
Screen Hotkeys
The screen hotkeys are to be handled differently than the Fn hotkeys.
They generate valid scancodes on the console and events when trying with
xev in X11. Perhaps, it is needed to add "Super is mapped
to the Win-keys (default)" in the layout settings of the
gnome-keyboard-properties. It used to be like that, but at
the moment it is not necessary anymore for some unknown reason.
The button with the "key" generates ctrl-alt-del and
can be configured with the gnome-keybinding-properties to
do a proper logout.
The button with the "switching screen" is more difficult to
configure, since a command for screen rotation is not included in the
aforementioned GNOME program. but with gconf-editor you can
set /apps/metacity/global_keybindings/run_command_1 to
"<Mod4>6" to get the key and
/apps/metacity/keybinding_commands/command_1 to
"/usr/local/bin/switch_orientation". You can use this
shell script
for switching. It calls xrandr for querying the current
rotation and sets the orientation accordingly.
The joystick is another story: It generates the same keycodes as the
keys from 1 to 5. So the shell script was extended to run
xmodmap to setup the joystick as keypad left, right, top,
down, enter when switching to portrait mode and to set it back to 1-5
(plus all the modifiers) when switching to landscape mode. The keypad
configuration enables the joystick to be used as normal arrowkeys or as
mousekeys when enabled by the accessX extension of X11, e.g. via the GNOME
accessibility keyboard settings.
