Four finger tap does not open the Dash

Instrumenting the toggleDash function says that this call

bool dashActive = dashInterface.property("active").toBool();

Takes very long (several seconds) and always returns false.

Logging calls added to DashDBus::activateHome() (dashdbus.cpp) never get printed, so I am assuming the D-Bus calls are failing silently.

If you know how to apply patches can you apply this one and see if it fixes your problem?

It does fix it. Thanks.

As an addition, you might want to fix Geis includes at the same time. Currently gesturehandler.h has this:

extern "C" {
  #include <geis/geis.h>
}

The extern C is no longer necessary, as Geis's headers are fully C and C++ compatible.

Hello Jussi, or anyone else affected,

Accepted unity-2d into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

With proposed enabled, the dash comes up with a tap. Thanks.

This bug was fixed in the package unity-2d - 5.12.0-0ubuntu1
