Jon Vaughan, thank you for updating your BIOS. Could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please just make a comment to this.
If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc7 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: bios-outdated-2.17 ** Tags added: latest-bios-2.17 ** Tags added: needs-upstream-testing -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1268365 Title: [Lenovo Thinkpad t440s] Touchpad periodically stops working Status in “linux” package in Ubuntu: Incomplete Bug description: Every 15 minutes or so, the cursor stops reacting to input from the touchpad or trackpoint. Unfortunately this machine has a "clickpad" instead of separate buttons and so it is impossible to use the machine without the touchpad, which means that Ubuntu is virtually unusable. In Windows on the same machine there is no problem.
