BTW, some Dell Precision 7510 systems (possibly only Xeon systems?) have a hardware issue where the trackstick or the touchpad or both will periodically get "stuck" (stop responding briefly) when on A/C power, when switchable graphics is enabled, when there is significant 2D or 3D video activity being rendered on the Intel video card, and when the Alps device is being run by an Alps driver (either this Linux driver or the standard Windows driver) instead of being run in PS/2 compatibility mode.
However, Dell is not taking my complaints about this seriously, in part because they "have not received any other complaints about this issue". If anyone else is encountering this issue, please contact me directly. -- 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/1590590 Title: Touchpad not recognized on Dell Latitude E7470 Ultrabook Status in linux package in Ubuntu: Triaged Status in xserver-xorg-input-synaptics package in Ubuntu: Confirmed Bug description: Expected: Touchpad settings available in Mouse & Touchpad Settings dialog Actual result: Touchpad settings missing entirely Details: The touchpad on my Dell Ultrabook (Latitude E7470) functions mostly.
