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 <replace-with-bug-number> 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: -
