KDE freezes when changing focus

KDE has been randomly freezing/stalling when changing window focus, opening, or closing programs. It does not seem to be restricted to any particular programs. If I change focus by clicking in a new window, often, when the system comes out of it’s frozen state, the mouse is still in a button down state even though I’ve released the click.
No errors are generated in /var/log/messages or in ~/.xsession-errors.
I’m running 11.3 and here’s the output of uname -a:

Linux dan-desktop 2.6.34.8-0.2-desktop #1 SMP PREEMPT 2011-04-06 18:11:26 +0200 x86_64 x86_64 x86_64 GNU/Linux

Desktop Effects are disabled.
KDE version 4.4.4-1.5

Rebooting the system generally get’s things running smoothly for a bit, but it doesn’t take long for it to start this behavior again.

Other than a wipe and fresh install, I’m not sure what to do to diagnose or fix this.
Any thoughts? Thanks a bunch.

has it always been like this, or did it suddenly start? after how long
working ok?

is this the first version of Linux run on that machine? if not, what did
openSUSE 11.3 replace, and in what way did you upgrade or switch repos
(did you keep home, or what?)

  1. how much RAM and what kind/speed CPU?

  2. have you adjusted power management or BIOS to cause (for example)
    hard drives to spin down when not in use for xx seconds, or to throttle
    back the CPU during low loading?

  3. if you click on “My Desktop” and look at the speed your CPU is
    running at, is it what you expected?

  4. while in My Desktop, note and report what kind of graphics card and
    which driver is in use…


dd CAVEAT: http://is.gd/bpoMD
[NNTP via openSUSE 11.4 [2.6.37.6-0.5] + KDE 4.6.0 + Thunderbird 3.1.10]
Dual booting with Sluggish Loser7 on Acer Aspire One D255

The problem started suddenly a month or a few weeks ago. It’s been working OK since 11.3 came out, can’t remember exactly when that was. I installed 11.3 on a fresh drive, not upgraded, didn’t keep home.

  1. RAM - 16GB, CPU Xeon X5272 3.4GHZ
  2. No adjustments have been done to the machine’s BIOS or PM.
  3. Speed is showing at 3.391.94 MHz, which seems right
  4. Quadro FX3700, running drivers direct from NVIDIA (256.44)

Thanks for the help.

i have not helped…sorry, and i have no idea how to…except it sure
sound like either a graphics problem or a drive spin down…or
something really strange in the software, which is not usual…

perhaps you can look in /var/logs/messages and see if something jumps
out at you…

OR, that is a pretty fancy new CPU right, maybe there is a bug in the
11.3 kernel…i’m out and hope a real guru can drop in and help

I have a similiar problem I think (should I make a new thread, or put it here).

For me, the computer freezes very shortly after the OS has loaded.
I tried a live disk of Kubuntu, it also froze.
I tried nomodeset and it didn’t freeze, but the mouse movement was slow and jerky.
I don’t think it’s a hard drive spin down, as I have checked the BIOS.

My graphics card is an Asus EAH 4350 Silent. If I need a specific driver to get it working, how do I get that on to the computer if everytime the OS has started (i.e I’m looking at the KDE desktop, ready to start my work, and 3 mins later it’s frozen - no movement from mouse or keyboard).

Thanks for your help.

When did you last update your nvidia driver or x11 or kde (a month ago?),
the current nvidia driver for 11.3 is 270.41.06 (available from nvidia
repository), if I where you I would try the update.


PC: oS 11.3 64 bit | Intel Core2 Quad Q8300@2.50GHz | KDE 4.6.3 | GeForce
9600 GT | 4GB Ram
Eee PC 1201n: oS 11.4 64 bit | Intel Atom 330@1.60GHz | KDE 4.6.0 | nVidia
ION | 3GB Ram

I seem to have the same problem.

KDE SC 4.6.3 with Xorg and kernel from Tumbleweed, using the intel i915 graphics driver. It started some weeks ago and happens at least once a day which is driving me nuts.

I suppose it is related to the Xorg stack update which came through Tumbleweed some weeks ago but I cannot be sure.

Here it is suspected that oxygen-transparent may be the one to blame (which I actually do use myself, how about you?): http://old.nabble.com/-Bug-274478--New%3A-Oxygen-Transparent-freezes-my-desktop-when-maximising-windows-td31729455.html

Anyone found a cure?
