_ZN9KListView9selectAllEb is C++ symbol mangling of KListView::selectAll
which sounds like a common standard KDE function so I checked the common
standard KDE library package first.  I already knew its name from many
installs over the years.

Ah yes, that could leave things in a bad state.  I suggest you run the
following (all on one line) to look for other possible problems:

dpkg-query --show --showformat='${STATUS} ${PACKAGE} ${VERSION} 
${ARCHITECTURE}\n' | grep -v 'install ok installed'

Mouse pointer and sound card problems are outside my area of expertise.
Hopefully somebody else can help you with those.
