Just based on the last test that I did, it would seem that the drivers in use in kernel 3.5.0-31 are different to the generic mouse ones in kernel 3.5.0-30 (looking at the output from xinput) - rather than that a bug was introduced into the same set of drivers.
If the generic mouse drivers work and the Alps-specific drivers cause problems - I'm not sure how it would help to bisect the commits; you would either have to revert to the generic drivers as a solution or try to debug the Alps driver without having a previous working version of those drivers as a starting point for investigation. -- 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
