Hello all,

Reviving this thread because I think I found the "perfect" Linux/TDE 2 in 1.

I don't like touchpads and the Surface Pro 2's was driving me mad, so I 
searched for a 2 in 1 with a track point or similar, and found the Toshiba 
z20t (it does have a touchpad too, if you like).

The model I got (for �300 on ebay) is the Z20t-B-113. As far as I can say 
everything works out of the box: Touchscreen, stylus, keyboard (except the FN 
special keys), touchpad (which I deactivated), track point, suspend and 
hibernate (from tde powersave menu).

The machine uses an Atmel touchscreen (that can be controled with xrandr) and 
a Wacom pen digitizer (which can be controled with xsetwacom).

I have not tried again to set up palm rejection, I find better to switch off 
the touchscreen when I need to write, so I wrote a tcl/tk applet to do this 
with xinput.

To my surprise xinput-calibration works in portrait mode on this machine (it 
does not on my thinkpad). Pen precision is not always perfect but globaly I 
can live with it.

There remain two small problems I'm working on:
- I get error messages about loading the iwlwifi modules (although wifi is 
working)
- when I rotate the screen (xrandr on "Atmel, ID 10) and the pen digitizer 
(xsetwacom on Wacom ISDv4 12C Pen stylus, ID 11) the touchpad/point stick 
pointer does not rotate (would be AlpsPS/2 ALPS DualPoint Touchpad / STick 
with IDs 14 and 15).

xinput lets me disable/enable but not rotate
xrandr works only on the screens
xsetwacom only works on Wacom devices 

Any idea how I could rotate the pointing device? Not so important because the 
stylus works but...

The keyboard is OK, the Tablet is light and nice, the digitizer is good, TDE 
works great and the machine has a second battery in the keyboard, so after 
setting up everything since last evening I still have 47% (given as more than 
10 hours) of energy (under lInux).

Have a nice day,

Thierry
