That machine was certified with Ubuntu 12.04. it's possible that there was some regression that happened in the Ubuntu 14.04 release, or possibly the hardware enablement kernel/X stack that you are currently using. Since it worked properly on Ubuntu 12.04, two options I would recommend: 1) Switch back to Ubuntu 12.04 OEM image 2) Try Ubuntu 16.04 from a live USB stick and see if this function works properly for you. If it does, then upgrade to the Ubuntu 16.04 HWE pack on Ubuntu 14.04 or reinstall Ubuntu 16.04. _______________________________________________ Linux-Desktops mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-desktops Please read the FAQ at http://lists.us.dell.com/faq
