[Solved] KDE4 Apps don't start and Pulseaudio broken after update

k3njiy · 2011-09-23 11:48:29

Hi,
I hope I'm posting in the correct forum.

So, I updated my arch and since then somehow the whole system seems broken.
Right-click on desktop crashes the desktop (everything, nothing works, have to change to tty1 to reboot), starting dolphin, systemstettings or konversation doesn't work (nothing happens, icon bounces around a bit and thats it. starting it via console doesn't result in any usefull output, matter of fact no output at all...)
And also pulseaudio stopped working. (Just saw that it seems to be working again after I deleted ~/.pulse*, can't test it though since I'm at university...)

My pacman log:

Can anyone please help me? I just can't seem to find a solution.

Thank you!

UPDATE: I suspect it has something to do with dbus or policykit, then again I hardly know anything about dbus nor policykit...
UPDATE2: Pulseaudio selected the dummy device, sound still doesn't work, also since I can't start KDE Systemsetting I can't change it and I don't want to go mess around in the config files of a broken KDE installation...

Dbus became the main suspect:

klauncher(1824) kdemain: No DBUS session-bus found. Check if you have started the DBUS server. 
kdeinit4: Communication error with launcher. Exiting!
kdmgreet(1804)/kdecore (K*TimeZone*): KSystemTimeZones: ktimezoned initialize() D-Bus call failed:  "Not connected to D-Bus server"

But dbus is installed and also in my daemons array...

And ps -e | grep dbus lists:

802 ?        00:00:18 dbus-daemon
1948 ?        00:00:00 dbus-launch
1949 ?        00:00:12 dbus-daemon

Is there no arch|linux|kde hacker online, that might have an idea what the puppies is going on? This is my productive computer and I need it for university and there's no change, I will install ubuntu just to have a functional system... i you guys|galls usually are always so brilliant

UPDATE
SOLVED: So, since nobody could help me, i turned to "The IT-Crowd" for help: "Have you tried turning it off and on again?"

Deleted my .kde4 Folder after I made a backup of it, deinstalled kde and dbus. Reinstalled it again and now it works. I didn't have to delete any configs in /etc/ . Since I didn't have anything important in my kde4 folder, I just manually configured my kde again the way I like it at thats it. Cannot say if restoring the original .kde4 folder would result in displaying the same symptoms again. So I also can't tell, if just deleting the .kde4 might be enough... See for yourself, if you ever have the problem. Just DON'T forget to make a backup!

Just documenting my workaround here in case anyone else has this problem.
