Description zetrotrack000 2013-08-30 16:10:50 UTC

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

Synaptiks is not developed nor tracked here.  Actually it is hardly maintained nowadays.

Anyway, the crash of systemsettings is probably related with bug 323899.

Comment 2 Eric Viveiros 2013-09-09 21:39:00 UTC

I have this problem using Arch Linux

Comment 3 Eric Viveiros 2013-09-10 17:36:05 UTC

(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.

Comment 4 Justin Phelps 2014-03-26 14:47:07 UTC

I'm also affected by this on Kubuntu 13.10.

Let me know what else you need.

Comment 5 Christoph Feck 2014-04-20 15:28:00 UTC

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.
