Tested with the newer kernel - running "uname -a" gives me: Linux wyvern 3.13.0-031300rc3-generic #201312061335 SMP Fri Dec 6 18:37:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
And in the logs: Dec 10 01:01:59 wyvern kernel: [ 814.172751] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 10 01:01:59 wyvern kernel: [ 814.173731] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 10 01:01:59 wyvern kernel: [ 814.174728] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 10 01:01:59 wyvern kernel: [ 814.177790] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - driver resynced.

I didn't get much of the "jumping around" behaviour - in fact, I didn't realise that anything was wrong in that sense until I looked in the logs. Also, a later message talked about losing sync "at byte 6" (rather than "at byte 1", which is the usual message). It's difficult to recreate the bug on demand, so I normally just have to use the system normally for a while until something happens. ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1258837 Title: Dell Latitude E7440 ALPS touchpad keeps having state reset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258837/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
