I'm a bit uncomfortable with the kernel test, as my technical skills are somewhat limited. But I'll give it a try later next week if I can free up some time.

It's difficult to position it when this happens, as I'll move the mouse and the pointer will react a later, sometimes a long as a second, and with little precision. Virtually unusable when it gets this way. I've checked system monitor for runaway processes, and nothing is hogging the CPU. The mouse is a Microsoft wireless (optical). This also occurred with a Logitech wireless mouse. --- ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: dan 2851 F.... pulseaudio /dev/snd/controlC1: dan 2851 F.... pulseaudio /dev/snd/controlC0: dan 2851 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=ce662c44-024f-4a63-86e9-7d90e45f6c50 InstallationDate: Installed on 2014-07-08 (91 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: LENOVO 20AQCTO1WW Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-36-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.13.0-36.63-generic 3.13.11.6 RelatedPackageVersions: linux-restricted-modules-3.13.0-36-generic N/A linux-backports-modules-3.13.0-36-generic N/A linux-firmware 1.127.7 Tags: trusty Uname: Linux 3.13.0-36-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 09/03/2014 dmi.bios.vendor: LENOVO dmi.bios.version: GJET79WW (2.29 ) dmi.board.asset.tag: Not Available dmi.board.name: 20AQCTO1WW dmi.board.vendor: LENOVO dmi.board.version: SDK0E50510 PRO dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGJET79WW(2.29):bd09/03/2014:svnLENOVO:pn20AQCTO1WW:pvrThinkPadT440s:rvnLENOVO:rn20AQCTO1WW:rvrSDK0E50510PRO:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20AQCTO1WW dmi.product.version: ThinkPad T440s dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1378533/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
