Hi

Has anyone ported linux to this device .. if so .. have you got
xstroke working and what other issues did you encounter?

Thanks

Stephen

I have a C110. SuSE 9.1 installed without much effort though I'm not
yet entirely satisfied with its functionality. The most helpful
information I've come across is at
http://www.math.uiuc.edu/ ~hartke/computer/tablet/tablet.php


- Standby and suspend modes do not work properly with ACPI. Suspend
does not work with APM.

- The Wacom digitizer was not configured properly by Sax2 so manual
editing of XF86Config was required.

- I was able to configure X with a rotated (portrait mode) screen but
the Wacom digitizer has some problem understanding screen coordinates in
this mode - the cursor doesn't follow the pen - and is not usable.

- I haven't used xstroke yet but I think it will work as long as the
digitizer is set up right.

- I haven't tried any wireless stuff yet.

- The Synaptics touchpad has a problem where it loses sync and jumps
randomly. Turning-off "dynamic frequency scaling" in power management
may have solved that though there is a hit on battery life.

- I haven't yet tried configuring the buttons around the tablet frame
nor the button on the pen.

I'm running Redhat 9 linux on my Toshiba 3500 tablet. Besides the fact
that the IR , MM/SD, and the digitizer/pen aren't working, now the
laptop will drop the usb connection after a couple minutes of reading
files from it. Attempting to remount the partitition (after a umount)
results in an invalid device error.  The error is repeated whether I
use kernel 2.4.20-8, 2.4.20-27.9, 2.4.20-28.9, or a custom kernel. 
Any suggestions?
