fwiw . . . I noticed this behavior with X for quite a while on 11.2 over several versions of the nvidia driver. It seemed to occur when I had Firefox open for a long time, having used a lot of tabs (low cpu but >600MB ram) and especially alongside kmail, again after having it open for a long time (so also using a hefty amount of ram).
Yes, that describes what I was seeing. About 40 tabs, half a dozen other application/windows open.
X would jump up to as much as 40%, but usually came back down on its own. But occasionally it stayed at the high cpu level and I noticed a response hit (this machine is 3.8GHz dual-core w/8GB ram) until restarting KDE, which would drop X back to usual.
This was a laptop with just 2G ram which might explain the higher %-age I experienced.
A couple months ago I searched bugzilla, but found nothing reported that fit, and I cannot reproduce the condition at will.
It took some discussions before finding. The high level phenomena (being triggered by firefox) and the low level cause (XSYNC) never seem to occur together in the bug reports. But then complex path interactions get like that. -- What is written without effort is in general read without pleasure. -- Samuel Johnson -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
