Comment 57 for bug 186713

Jerson,

Sika has posted a working fix for this issue. In the launch script, /usr/bin/keytouchd-launch, repacing the lines to kill keytouchd by pid with killall keytouchd-launch will reliably terminate both processes on logout without hanging.

Sika's corrected keytouchd-launch:

I can confirm both the bug and this solution.
