Colin Taylor, as per http://www.dell.com/support/home/us/en/19/product- support/product/latitude-e7440-ultrabook/drivers/advanced an update to your computer's buggy and outdated BIOS is available (A15). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags removed: latest-bios-a10 ** Tags added: bios-outdated-a10 ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- 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/1382702 Title: [Dell Latitude E7440] Touchpad out of sync Status in linux package in Ubuntu: Incomplete Bug description: The touchpad repetitively gets out of sync, causing the mouse to jump around and randomly click things: [ 399.788431] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 6 [ 399.798582] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - driver resynced. WORKAROUND: Loading the psmouse driver with proto=exps largely avoids the problem, but has the side effect of merging the trackpad and the nub together as one input device (so you can't disable the trackpad and just use the nub). Setting reset after on the driver does fix the random moving and clicking, but causes the CPU to thrash as it constantly disconnects and reconnects to try to "resync."
