Yasuhiko, All, I just had the relatively normal "Knotify Crash" and was going to look at ksysguard to see if there was anything funny going on. Starting ksysguard, the window opens and all looks fine -- but nothing is updating, it's just dead. Can somebody open ksysguard on Tumbleweed and see if it updates on your system. My normal "Knotify Crash" is the old random crash that disables system sounds for your sound theme: jack_client_new: deprecated Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock akode: Guessed format: xiph KNotify::playTimeout KNotify::playTimeout KCrash: Application 'knotify' crashing...

Just random. I don't know if the knotify crash effects ksysguard updating, but I thought I would include it for completeness. If you have other ideas what to check let me know. ps still shows knotify running, but the sound theme is dead, e.g. 13:38 wizard:~> ps axf | grep notify 89933 pts/2 S+ 0:00 | \_ grep --color=auto notify 83171 ? S 0:00 knotify [kdeinit] Also, does anybody know how to restart the sound theme or sound server from the command line? I'd rather do that than logging out/in if possible. Thanks! -- David C.
