Thread: Sometimes kickoff menu hangs long time while typing appname

  1. #1

    Default Sometimes kickoff menu hangs long time while typing appname

    Sometimes I get this weird thing where typing a name into the kickoff menu hangs after a few letters. It hangs the entire computer! Once it happens, I try to close it but have to wait about 20 seconds before I can do anything on the computer. Then everything else works fine (after it's closed). But if I go back to kickoff and try again, it does the same thing! I can't seem to find anything in "top" to indicate what's happening.

    openSUSE 11.2
    KDE 4.3.4
    Linux 2.6.31.8-0.1-default i686
    AMD Sempron(tm) Processor 3100+ 1.8 GHZ
    nVIDIA G98 GForce 8400 GS with nvidia driver

    Total memory (RAM): 1.4 GiB
    Free memory: 541.6 MiB (+ 506.1 MiB Caches)
    Free swap: 2.0 GiB

    Here's "top" during a recent issue where konqueror wasn't opening to show sysinfo and there was some hanging (although this was after it came back from kickoff hanging):
    Code:

    When I run top while it's hanging in kickoff, it doesn't show anything unusual. No high usage of the CPU, no app jumping to the top with 90% (in fact nothing above 7%)

    Any ideas?

    Default Re: Sometimes kickoff menu hangs long time while typing appname

    OK, I discovered a bit more. I went into kickoff's "Menu Editor" and everything was fine until I clicked to create a new item. Then it hung for 14 seconds! From there, anytime I actually changed something or interacted with the "system" itself, it would hang. It seems that all the hanging has to do with when I'm interacting with the system itself.




    PLEASE, Someone help me!

    Thanks for PM'ing me.

    IIRC you seem to have quite a number of issues generally. And I'm fairly sure you have already started a new .kde4

    I say this because this hanging, seems like a config issue. But I could be wrong.

    What I would do is this: Open a terminal and set 'top' running and set it so it is always on top.
    Now perform the action that brings everything to a standstill and you should be able to watch top as all this is going on.

    Then report back here

    OK, here's what I notice (only two things seem weird):

    1. Nothing in top jumps above 5% of the CPU during this hanging

    Here's the weird
    2. There's 138 sleeping tasks (is that a lot?)
    3. It says there's 4 total users, but when I type "users" at the command line I just get my login name (UserGuy) 4 times! What does that mean?

    Other than that I don't see anything out of the ordinary yet.

    This all sounds OK/Normal to me.

    And you are not getting any crashes, so it's going to be difficult to pin down.

    Should I try changing .kde4 (i.e. delete that folder, log out and log back in)?

    Also, what things should be in the .kde4 folder? For example, why do I have nsplugin.desktop share/kde4/services?

    If you logout and then login with console
    http://public.bay.livefilestore.com/...sole.login.png

    At the CLI enter your user name and password
    then at the prompt type the following

    Code:
    mv .kde4 .kde4-oldbak
    to start the desktop now type: startx
    =======================================
    The above will rename your current folder and when you starx the new .kde4 will be formed. We can always roll back to your oldbak if this doesn't help.

    Thanks, I'll give that a try and let you know how it goes. It'll probably take a full day before I can tell if it's working.

    Hmmm...now my USB headset no longer works and KMix no longer shows up in the system tray.
