    Slow KDE?
    Contributed by Anonymous on Thursday, February 07 @ 07:05:33 GMT

    I am running woody and i do a apt-get upgrade every day.
    Since the last few days i discovered a slowdown of all my kde applications.
    They take a long time to load and the gui's are reacting with a delay of up to 10 seconds.
    This behaviour doesn't appear when kde isn't started directly by kdm but called from a xterm.
    Every user on the system is affected.
    The problem deosn't seem to be in kdm because every other window-manager is working fine.
    Even the xterm from which kde works great is a failsafe session of kdm.

    DanielS: Are you sure you're starting it with "startkde"? If not, it can take some time for services normally started by startkde to start. I also recommend running sid, because KDE in woody is a bizzare hybrid of 2.1 and 2.2; this may also give you grief.

    Ok, i installed kde from sid but that doesn't make any

    difference. I also discovered no difference when

    useing startkde instead of kde2.

    Have a look for some error codes:

    Look in ~/.xsession-errors

    Also if the KDE sound server is not starting
    correctly then it can cause startup delays, while
    timeout occur.

    Maybe KDE 2.2.2 packages have debugging on, non-optimised
    Maybe KDE2.2.2 is just bigger?
    To test login to kde as norm:

    # su -
    # export DISPLAY=:1
    # X :1 & ( move back to :0 CTRL-ALT-F7 )
    # kde2 ( look at error messages)

    Hope this helps.🙂

    I've had this problem for a while trying to run konqueror (I don't use kde).

    DCOPClient::attachInternal. Attach failed Could not open network socket
    _KDE_IceTransmkdir: Owner of /tmp/.ICE-unix should be set to root
    iceauth: timeout in locking authority file /home/caoilte/.ICEauthority
    IO error opening ICE Connection!

    kdeinit: DCOPServer could not be started, aborting.

    haven't been able to test our site on konqueror much. :(.

    I'm running sid and as of last Saturday, when I apt-get upgraded my box, KDE has not only been slow, but leaking memory like a sieve. I did not change anything (I still start from kdm), yet all the KDE apps show significant slowdown on start-up. My box, btw, is a K7 1.2GHz machine with 512MB memory. It should not take a bloody twenty seconds for Kmail to start!!! I have to reboot every day, since my memory fills up within a couple of hours, even when I'm not doing anything. (To make sure that this is a KDE problem and not with X, I booted into fluxbox and left it running with no problems.)

    Isn't this post more suitable for debian help?

    Just to provide another viewpoint I am running the latest kde in sid without any slowdown problems. I start kde using kdm just like I have for a very long time now. I run arts as realtime and it runs in oss mode to my sblive driver that I built into the 2.4.17 kernel. I have not noticed any problems with it so far and I have been using it a lot. I have XF 4.1, a K6-2 500, 768M of ram, a 64MB Radeon DDR card, and a VIA chipset motherboard.

    I did notice I used to have speed problems when I had my geforce card but when I replace the card all the stability and speed problems went away. I don't seem to have any memory leaks with the kde in sid and I have about 20 kde apps open right now including kdevelop and lots of konqueror for working with zope.

    I'm happily running woody's KDE - which is becoming more 2.2.2 with each dist-upgrade.

    I can't say I've noticed any problems with slow performance other than the main startup sequence going through the various initialisation steps. Compared with GNOME 1.4 it's still faster though.

    The only thing I had to do was add my account to groups audio and floppy to keep arts and floppy formatter happy. Otherwise every KDE application I've tried (except broken ones like KOffice) appears to work fine.

    Recently I was talking to some of the other KDE developers and they were telling me of some LD_BIND_NOW problems we are having. IT turns out that when you start an app with LD_BIND_NOW=1 it triggers some bug in XRender. This bug has been reported and a patch awaits.

    I am not sure if this affects speed, but when you start an app from kicker (the panel) less symbol relocations need to be done as kdeinit starts it. Hopefully this should all be fixed soon enough.

    Most likely: Something's hogging the CPU.

    Run top and see.

    I did some investigating in this slow KDE. It seems that if you start KDE from kdm as a normal user, the DCOPserver will fail as suid and restart under the logged in user. This sets up /tmp/.ICE-unix to be set as the logged in user. Does anyone know how to prevent this from happening without logging in as root from kdm first after rebooting?
