[KDE] 4.6.2 - kded4 eats 100% of a CPU core

student975 · 2011-04-06 14:10:23

After upgrading to 4.6.2 I have noticed a kded4 process eating 100% of a CPU core (switching between cores). I have terminated the process, the DE is still live.

I start the DE with startx, having 'exec ck-launch-session startkde' in ~/.xinitrc.

Any thoughts wrt to this brave kded4?

P.S. Also sensors are not visible in ksysguard at all, but this is another story.

Same problem here.

I just use standard KDM to launch KDE.

I noticed something pretty interesting. When I kill the kded4 process, the icons in the tray lose their theme and revert back to the classic tray icons.

All KDE-specific daemonds stop when kded4 is terminated. You can find them in system settings (something like "startup"). I have tried to stop each of running daemons without any success.

confirm this, 64bit

student975 · 2011-04-06 15:01:48

Ctrl-Esc (system activity), tool tip of the kded4 process (in CPU column) shows last one has Read syscalls at ~800000 per second.

It also happens on a new user account.

Thanks! - it's very strong argument.

birdflesh · 2011-04-06 15:25:41

It is caused by the new ntrack version. Just downgrade to 013-1 and it is fixed.

ewaller · 2011-04-06 15:32:01

Anyone experiencing this problem care to take a crack at filing a bug? I'm not seeing the problem, so I really can't

Here it is: https://bugs.archlinux.org/task/23612

OdinEidolon · 2011-04-06 15:51:51

Had this problem for some weeks, but killing kded4 and restarting it solved it everytime. Doesn't happen anymore tho.

student975 · 2011-04-06 16:22:29

Yes, after ntrack downgrading kded4 stops eat a CPU core. But at some point knotify4 starts the same song (eating 100% of a CPU core).

I just updated all 4 of my Arch machines (1 laptop 3 desktops) all 32bit . And all of them are eating 50% power from the kded4 process . I am thinking about deleteing my .kde4 file to see if that makes a diff . For now I will use E17, my backup DE.

Stop deleting! See above - NEW kde user has the same problem.

This problem was also present in 4.6.1, maybe even in 4.6. At least for me. Killing it solves, but brings strange issues such as tray loosing icons, as mentioned earlier, and other minors.

Andrenas · 2011-04-06 17:22:48

I solved the same problem downgrading ntrack.

Hyugga · 2011-04-06 19:09:42

Downgrading ntrack solve the problem for me.

jlacroix · 2011-04-06 19:31:58

An update hit the repositories and now I don't have this problem anymore.

AurosGamma · 2011-04-06 20:05:57

Confirmed, the update(ntrack package) solved the issue
I think that now the topic is solved

Thanks for that. I was about to ask right now xD on me it just eaten 17% and i thought "why the hell is my cpu cooling like hell? Its just 17%"

But i always used single or dual-core and now have an Phenom II X6 which have 6-Cores.

Everyone with a bit of math knowledge knows, 100/6 = 16,66

thanks a lot for that information i had to use the PKGBUILD in case of my mirror and now its solved. I was that short about switching to GNOME as long this is not fixed xD you saved me a lot of time

it was there for me also. and even now is present in KDE 4.6.2 + ntrack 1:13-1.

after looking into logs, only kdm.log seems to have kdeinit in it.

klauncher(3404) kdemain: No DBUS session-bus found. Check if you have started the DBUS server. 
kdeinit4: Communication error with launcher. Exiting!
kdmgreet(3398)/kdecore (K*TimeZone*): KSystemTimeZones: ktimezoned initialize() D-Bus call failed:  "Not connected to D-Bus server"

and a shot

so, this is not quite solved.

@JokerBoy Maybe your problem is a config file, because is a little weird that the problem was not solved for you
Try to create a test user and see what happens

JokerBoy · 2011-04-07 03:22:18

it's a fresh install with new users.

$ head -1 /var/log/pacman.log

I'm still having this problem too. It can be easily reproduced on my machine just suspending and waking it up again. There are several bug reports on the kde site e.g https://bugs.kde.org/show_bug.cgi?id=257493
