Thread: Long Delay then *Bam!

  1. #1

    Default Long Delay then *Bam!

    Hi there,

    I have a 12.2 install running pretty much flawlessly on a Lenovo T430, flawlessly except one issue that keeps happening and used to happen on a 12.1 install on a T420 laptop.

    The issue is randomly when opening a new application everything just hangs. You can still interact with the desktop, so you can find apps and click them but nothing happens. Same with in a terminal you can type but as soon as you hit return it sits there. It will sit there for a few minutes and then all of a sudden "bam" everything opens all at once.

    Rebooted/Updated/Reinstalled OS and still this keeps happening.

    Its not like a full hang, just totally random. Happened in both KDE and GNOME. Currently running GNOME. Also, if I ditch X all together it still happens.

    Thanks in advance.

    if you open top in a konsole/x-term/etc and leave it open on your
    desktop so that you can see it at all times....do you see one or more
    processes jump to the top of top's list and hog lots of CPU or RAM??

    which processes might those be?

    Having had some experience on Intel HD4000 video chips, I suggest you try a 12.3 RC2 KDE LiveCD, boot from it and try to get it down on it's knees. It could very well be the NVIDIA Optimus technology with openSUSE 12.1 that's causing this. The newer kernel of 12.3 has lots of improvements, also in the Intel graphics field.

    Thanks for the responses. I just have the Intel HD4000 in this T430, no optimus. I tried the 12.3 RC2 install and things were pretty crippled on the laptop, so I went back to 12.2. Its pretty random though, although it seems to happen pretty quickly once I fire up a VPN connection using Sonicwall's NetExtender VPN Client.

    are you running the Linux client?

    maybe you need to touch base with the DELL folks..

    maybe they have a newer version ready to use with your newer
    kernel...or, maybe you have to run an old kernel!

    and, you didn't answer my earlier question!

    Well.. I did a clean install without the VPN client and it still is acting up.....

    I'll start up a terminal and keep top going to see if I can pinpoint it.

    I'd suggest you run the long test of the smartctl program on your disk(s).

    Also I did finally get a good sampling of watching top as it was happening. Nothing is going on. Its as if the system is idle and then all of a sudden large spike when program actually opens.

    Then use iotop or iostat.
    Also check the disk as I mentioned.

    Also if its a terminal window that was lagging coming up it will come up as a "I have no name@computername"
