Hi Anthony, I have verified with the drm-intel-nightly kernel (version 4.0.0-994) on 201403-14892, and it could get rid of the unknown display.

A workaround to get rid of this Unknown display is to change: GRUB_CMDLINE_LINUX= into: GRUB_CMDLINE_LINUX=video=VGA-1:d (Since the bogus unknown display is connected to VGA1) Run sudo update-grub and reboot Reference: http://askubuntu.com/questions/398903/unknown-display-besides-laptop-built-in-display-old-question-but-with-no-answer Also note that there is only a HDMI port on this system. ** Also affects: hwe-next Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1393651 Title: [Dell Inspiron 3531] Unknown display found in display utility [8086:0f31] To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1393651/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
