http://bugzilla.novell.com/show_bug.cgi?id=584919 http://bugzilla.novell.com/show_bug.cgi?id=584919#c0 Summary: Xorg uses 99% cpu after short period of inactivity on T61 laptop with KDE 4.4 Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: x86 OS/Version: openSUSE 11.2 Status: NEW Severity: Major Priority: P5 - None Component: X.Org AssignedTo: bnc-team-xorg-bugs@forge.provo.novell.com ReportedBy: mtgibbs@yahoo.com QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/533.2 SUSE/5.0.342.0-2.1 (KHTML, like Gecko) Chrome/5.0.342.0 Safari/533.2 I moved to KDE 4.4 (have the latest packages from KKFD) and after I unplug and then plug in the laptop Xorg will start using 99% CPU after the system is idle for a couple of minutes. The CPU usage seems to be normal when the system is not idle. If I log out and log back the problem goes away until I switch to battery and back to AC power. This is a T61 with Intel graphics. Reproducible: Always Steps to Reproduce: 1. Log in to KDE 2. Unplug AC power 3. Plug in AC power 4. Start top and let the system sit for a couple of minutes. Actual Results: Xorg will use 99% CPU. Expected Results: Xorg uses minimal CPU.

Thinkpad Z60t with Intel mobile 915 GM. openSUSE 11.2 with KDE 4.2 from factory repositories.

100% cpu usage after some idle time has been solved by adding repository http://download.opensuse.org/repositories/X11:/XOrg:/11.2/openSUSE_11.2/ and installing xorg-x11-driver-input 7.4-41.1-i586 and xorg-x11-driver-video 7.4-87.93-1-i586

The cpu usage problem has come back again. I don't know why it didn't happen for several hours after updating the xorg drivers. There must have been some other factor that I had altered. I'm back to trying to figure this thing out again. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Holger, thanks for your test case. My factory test box is grossly outdated as i found out so i'm in the process of updating it. You are saying that you only get the alarm once - this reads to me you don't ever get any other alarm even after a reset. This is strange as how I read the code the trigger gets readded to a counter every time the alarm is re-set. I need to check this more deeply once my box is updated. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

...

Egbert, please clarify, I understood the header change === the api change, and you were saying it shouldn't be a problem to backport for 11.2.

X.Org as shipped with 11.2 has the structure SyncAlarm defined in syncstr.h which is part of the xextproto package which we ship with xorg-x11-proto-devel. However the part of the header where this structure is defined is protected by: #ifdef _SYNC_SERVER . #endif this used to be defined in the server, an X library or user space program should never define this. To overcome the necessity to touch a proto package when a server internal structure changes the parts wrapped by above #ifdef are now (xserver 1.8) moved to a header contained in the server. The proto package has been updated as well. Thus there isn't really any client api change. Only the fact that a client visible X header historically contained some server internal structures. Thus doing this for 11.2 will not introduce any change to any API outside the server. Still the requirement to modify this header will require the proto package to be updated and in turn *all* packages depending on X headers will start to rebuild. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Most likely KMS is not active. KMS wasn't active on 11.2 kernel by default. If KMS is not available X falls back to fbdev driver. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
