Daniel Drake, as per https://downloadcenter.intel.com/product/78953 an update to your computer's buggy, insecure, and outdated BIOS is available (0053). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
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. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-0053 ** Tags added: kernel-bug-exists-upstream-4.6-rc6 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed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/1574758 Title: i915 HDMI display turns off during boot after upgrade to 16.04 Status in linux package in Ubuntu: Incomplete Bug description: Ubuntu 15.10 was working fine, but on upgrading to 16.04, my HDMI display goes into low-power mode once the kernel starts booting.
