system clock slowdown, but only in KDE

cbueche

Hi all,

hardware : Dell Inspirion 5000e, BIOS rev6
OS : gentoo, latest updates
desktop : KDE 3.0.1
hwclock : set to UTC
timezone : MET

my problem is the system clock slows down while in KDE.

I made the following tests :

I already tried to del /etc/adjtime and reboot, it doesn't help. NTP doesn't even synchronize, it thinks he is 2 hours ahead.

My guess : KDE tries to correct the system clock, but I can't figure why and how.

Hints welcomed,
Charles

But the KDE would bring a new fact to light.

Hi again,

I *do* run /dev/rtc, so the problem is probably KDE (or a subcomponent like X / mouse / whatewer app runs on top of this)

<sorry to cross-post, it seems both threads track the same problem>

The problem is caused by kmix. Kill it, the clock doesn't shift anymore.
It took me a lot of kills to find it.

method :

- run "ntpdate -d $timeserver" in a 60 second loop, notice how the offset grows.
- kill things you suspect to be wrong
- watch the offset (continue to grow means you need to assassin more stuff)

I don't even have kmix running! Yet I still get the problem.

What else did you kill?

I killed the following applets : ksysguard, system monitor, kmix
on my box, kmix was the problem

well, the time is still too slow, it shifts back 0.1 seconds every 2 minutes. However, this is OK, as ntp can now "hook" the time and keep it.
