The problem suddenly starts to appear. When I try to start "synaptiks", kde gives error: KDEInit could not launch '/usr/bin/synaptiks' When try to run from terminal, it gives following error: Segmentation fault (core dumped) PS: few days ago, after upgrade, the kde stopped loading with error "desktop shell could not load" and I fixed it by removing ~/.kde4/share/apps/plasma directory. Reproducible: Always Steps to Reproduce: 1. Run 'pacman -Syu' to upgrade system 2. Go to 'kickoff Launcher' 3. Run 'synaptiks' Actual Results: kde gives error: KDEInit could not launch '/usr/bin/synaptiks' Expected Results: Synaptiks should run and allow user to use/change touchpad settings When go to 'system settings' and run 'touchpad' it crashes, here is the backtrace: Application: KDE Control Module (kcmshell4), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

I have this problem using Arch Linux
(In reply to comment #2) > I have this problem using Arch Linux I just did a system update on arch linux. sudo pacman -Syu I also had a problem with kate not launching in the kickoff application launcher which I changed the line: X-DBUS-StartupType=Unique to X-DBUS-StartupType=none in the file /usr/share/applications/kde4/konsole.desktop I'm not sure if the second part is need but the problem is now fixed for me. On a side note when launching synaptiks from konsole I get the following warning message: QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
I'm also affected by this on Kubuntu 13.10. $ synaptiks Traceback (most recent call last): File "/usr/bin/synaptiks", line 5, in <module> from pkg_resources import load_entry_point File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2805, in <module> working_set.require(__requires__) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 696, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 594, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: pyudev>=0.6 $ synaptikscfg Traceback (most recent call last): File "/usr/bin/synaptikscfg", line 5, in <module> from pkg_resources import load_entry_point File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2805, in <module> working_set.require(__requires__) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 696, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 594, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: pyudev>=0.6 Let me know what else you need.
Synaptiks is unmaintained since years. Please try "kcm-touchpad", which ships with Kubuntu 14.04 by default, and should also be available for other distributions. Please ask in a forum of your distribution for packages.
