[Bug 746084] Re: [i945gm] Stuttering mouse with Natty Narwhal
This is fixed for me with the current Natty updates. (Actually it's fixed since a while, otherwise Natty would not have been usable for me.

[Bug 746084] Re: [i945gm] Stuttering mouse with Natty Narwhal
Gunter Ohrner, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Please let us know your results. Thanks in advance. ** Description changed: Binary package hint: xserver-xorg-video-intel I just upgraded from Kubuntu 9.10 via 10.04 and 10.10 to 11.04-dev. Since 10.10 the mouse sometimes "stutters" while moving, freezing for a - few hundred milliseconds. Similar behaviour has been reported for - Maverick before (#595764, #599068, #662946, #658747), however in these - cases it seems to have been limited to i8xx GPUs while I use an i945... - Additionally, I could not find reports of this problem re-occuring (or - still occuring) in Natty, so I'm reporting it here. + few hundred milliseconds. The mouse stuttering / short freezes are much better than with Maverick, where even the sound was affected, but it's still pretty noticeable and annoying / distracting. Using "top", I noticed a kernel thread called "kworker" being listed among the top-5 processes in the process list refresh following such a "mouse stuttering". - - I'm not sure if any further information is neede, I'm happy to provide - whatever I can to help resolve this problem. - - Gunter ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: xserver-xorg-video-intel 2:2.14.0-4ubuntu4 ProcVersionSignature: Ubuntu 2.6.38-7.39-generic 2.6.38 Uname: Linux 2.6.38-7-generic x86_64 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: kwin DRM.card0.DVI.D.1: - status: connected - enabled: enabled - dpms: On - modes: 1920x1080 1680x1050 1280x1024 1280x1024 1440x900 1440x900 1280x960 1152x864 1024x768 1024x768 1024x768 832x624 800x600 800x600 800x600 800x600 640x480 640x480 640x480 640x480 720x400 - edid-base64: AP///wAmzQxWuwMAACwUAQOANB14KmBBplZKnCUSUFS/7wCBgIFAcU+VAJUPswABAQEBAjqAGHE4LUBYLEUACSUhAAAe/QA4TB5TEQAKICAgICAg/ABQTDI0MDlIRAogICAg/wAxMTAwNU0wQjAwOTU1AZsCAwgAQxITHowK0Iog4C0QED6WAAklIQAAGAEdAHJR0B4gbihVAAklIQAAHgEdALxS0B4guChVQAklIQAAHowK0JAgQDEgDEBVAAklIQAAGAAA4w== + status: connected + enabled: enabled + dpms: On + modes: 1920x1080 1680x1050 1280x1024 1280x1024 1440x900 1440x900 1280x960 1152x864 1024x768 1024x768 1024x768 832x624 800x600 800x600 800x600 800x600 640x480 640x480 640x480 640x480 720x400 + edid-base64: AP///wAmzQxWuwMAACwUAQOANB14KmBBplZKnCUSUFS/7wCBgIFAcU+VAJUPswABAQEBAjqAGHE4LUBYLEUACSUhAAAe/QA4TB5TEQAKICAgICAg/ABQTDI0MDlIRAogICAg/wAxMTAwNU0wQjAwOTU1AZsCAwgAQxITHowK0Iog4C0QED6WAAklIQAAGAEdAHJR0B4gbihVAAklIQAAHgEdALxS0B4guChVQAklIQAAHowK0JAgQDEgDEBVAAklIQAAGAAA4w== DRM.card0.LVDS.1: - status: connected - enabled: enabled - dpms: On - modes: 1280x800 - edid-base64: AP///wBEky4PAQOAGhB4CtLwllhOkSgjUFQBAQEBAQEBAQEBAQEBAQEB6hoAgFAgEDAVIEQABaMQAAAYDwAIGBJyAQoCMh6gBDIB/gBRVUFOVEFESVNQTEFZ/gBRRDEyVEwwMTEKICAgAGA= + status: connected + enabled: enabled + dpms: On + modes: 1280x800 + edid-base64: AP///wBEky4PAQOAGhB4CtLwllhOkSgjUFQBAQEBAQEBAQEBAQEBAQEB6hoAgFAgEDAVIEQABaMQAAAYDwAIGBJyAQoCMh6gBDIB/gBRVUFOVEFESVNQTEFZ/gBRRDEyVEwwMTEKICAgAGA= DRM.card0.VGA.1: - status: disconnected - enabled: disabled - dpms: Off - modes: - edid-base64: + status: disconnected + enabled: disabled + dpms: Off + modes: + edid-base64: Date: Thu Mar 31 00:04:12 2011 DistUpgraded: Log time: 2011-03-30 20:52:28.836629 DistroCodename: natty DistroVariant: kubuntu GraphicsCard: - Intel Corporation Mobile 94

[Bug 746084] Re: [i945gm] Stuttering mouse with Natty Narwhal
Hello everyone, I also have the issue on a Thinkpad T500. Rolling back to 2.6.35 did not solved it, but on 2.6.34 I don't have the issue. upgrading to 2.6.39-02063903 also did not solve the issue. however on my laptop it is quite better than the with the default kernel. The system is unusable with that... I would be also glad to provide any logs and information you need for resolving the issue. By the way I have a bug uploaded also about the same topic: it can be related to this I guess: Bug #772704 I may think that it may somehow related also to the wifi card/driver, as usually during these periods when kworker eats up my cpu (it uses more than 50% of the cputime) the system often dropped from the wifi access point as well. If anyone has a solution, it would be great to have, as this is a really annoying issue, and makes working impossible on the system.

upower bug above describes a freeze/hang approx. every 30 seconds Much more frequent interruptions in my case. Anyone else?
