Hello everybody,
I've got an interresting puzzle:
I've set up a Thinkpad X220 Tablet with OpenSUSE 13.2 and TDE 14.0.1;
Everything works wellincluding the Wacom digitizer, I've been able to
install
Open Sankore and MihPhoto from respectively a deb and an rpm package.
TDE 14.0.1 on OpenSUSE seems to have a problem with this machine as it
does
not see my USB key as removable, but a workaround was setting a mount
point
in fstab.
The puzzle is this: TDE proposes a system tray applet named "Resize and
Rotate". It works like a charm, wich is usefull because the X220t's
battery
is a little bulky and lifts the back of the computer This is good in
Notebook
mode, but in Tablet mode, with the screen _physicaly_ rotated 180°, it's
the
front that is higher that the back. So if I rotate the screen _per
software_
180° everything is fine... However, the digitizer does not get the
information, so the pointer appears on the wrong side of the screen - this
is
funny for 30 seconds but unusable after that.
So, does anyone have an idea how to also rotate the touchscreen digitizer
180°? This does work in Windows 10, but I'd prefer to use Linux :)
Have a nice evening,
Thierry
Interesting! I've never had the opportunity to use TDE on a tablet
computer, so I'm somewhat surprised it's working even that well.
I'm not sure if the issue described is TDE's fault or Xorg's fault. While
TDE is admittedly completely unaware of the digitizer (primarily due to a
lack of relevant hardware in the hands of the TDE developers), I would
have thought that Xorg would have matched the digitizer settings to the
screen after TDE made its xrandr calls.
A quick Google search show that this might be an Xorg bug:

There is also a potential workaround via the wacomrotate package:
https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/217182/comments…
Most likely we need to:
1.) Make TDE aware of the digitizer (you can help with this by sending in
the terminal spew generated when you execute "tdecmshell hwmanager")
2.) apply whatever workaround is in that wacomrotate package when screen
rotation is requested via tdehwlib.
