Comment 13 for bug 1297692

That's good news. Does multi-touch work too when you set touch input to 'multi-touch'? For example, hold Shift with one finger and tap any letter with another. Your screen says it can handle two touches.

Yes, I'd be great if you tried to run Onboard from source. I'd still like to figure out why it does nothing when wacom gestures are on and touch-input is 'none'.

The tedious part is getting the dependencies. base-devel and bzr for sure, but I don't have a full recipe for Arch, unfortunately. The debian packages are listed in the build-depends section in debian/control. If you get stuck let me know, I planned to install a fresh Arch partition anyway.

bzr branch lp:onboard
cd onboard
./setup.py build

It runs from the source directory, no need to install.
./onboard

When you got it running, make sure event source is 'XInput', touch-input is 'none' and the wacom gestures are on. Then
killall onboard; ./onboard -d event &>X220t_onboard_debug2.txt

The 'event' debug level is new and should print a lot more than before.
