Daniel Lynn, as per https://www.asus.com/Motherboards/H81T/HelpDesk_Download/ an update to your computer's buggy and outdated BIOS is available (0803). 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, if the problem is still reproducible, and the information above is provided, then please mark this report Status New. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-0803 ** Changed in: xserver-xorg-video-intel (Ubuntu) Importance: High => Low ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1450581 Title: Hardware accel causes X segfault with SNA renderer Status in xserver-xorg-video-intel package in Ubuntu: Incomplete Bug description: Release: Ubuntu 15.04 (vivid) Package Version: 2:2.99.917-1~exp1ubuntu2build1 I'm experiencing a consistently reproducable segfault when attempting to use hardware acceleration.
