Only two components listed above were updated in this cycle, so one of
them must be it, unless it's outside of X. Previous versions, working ok:


I'm going to experiment a bit, perhaps it's something in the application
mix (like, broken Firefox update). Although, no other applications eat
CPU together with X.

Also happens on x86.  Also happens with openchrome and vesa drivers.

Comment 2 Pete Zaitcev 2008-12-10 21:48:13 UTC
BTW, kernel would be the most natural culprit, but as it happened X fails
to start on the newest kernel 2.6.28-0.121.rc7.git5.fc11. So I am running
the old, unchanged kernel. The xorg-x11-server-* packages were not updated
since November 24 (xorg-x11-server-Xorg-1.5.3-5.fc10).

Another thing: my X stops using the CPU when screen blanking engages,
no matter what applications are doing. If an input unblanks the screen,
X starts eating CPU again on my system.

Comment 3 Yanko Kaneti 2008-12-11 00:15:53 UTC
Sounds very much like bug 474586

Comment 4 Pete Zaitcev 2008-12-11 00:45:57 UTC
Reverting to gnome-screensaver-2.24.1-2.fc11 on my system resolves the issue.
