Given that your apport output is from the previous kernel, this line is very suggestive:
[ 18.073838] fglrx: module verification failed: signature and/or required key missing - tainting kernel The 3.13.0-92 kernel is the first one in this series which implements Ubuntu's updated SecureBoot policy, which requires specific action by the machine administrator in order to allow unsigned modules. You should have been prompted for this on upgrade. Do you remember seeing such a prompt? Can you please attach the output of the following command: $ debconf-show shim-signed To successfully upgrade to the new kernel, you will want to: - run 'sudo update-secureboot-policy', and choose to disable SecureBoot - run 'sudo apt-get install linux-signed-image-generic' - reboot to the UEFI prompts, in order to confirm the SecureBoot policy change. -- 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/1603655 Title: After update, xorg will not boot Status in linux package in Ubuntu: Confirmed Bug description: Last night, Ubuntu Software Updater installed a round of updates. I shut down my computer, and when I booted this morning, the GUI failed to load or run at all. I switched to a terminal with Ctrl+Alt+F1, which worked fine. I tried rebooting into 3.13.0-91 via GRUB, at which point the GUI worked fine. Examining Ubuntu Software Center History, the new linux-image stood out, so I tried uninstalling that first. The command I ran was: sudo apt-get remove linux-image-extra-3.13.0-92-generic:amd64 linux-image-3.13.0-92-generic:amd64 linux-signed-image-3.13.0-92-generic:amd64 && sudo apt-get install linux-image-extra-3.13.0-91-generic:amd64 linux-image-3.13.0-91-generic:amd64 linux-signed-image-3.13.0-91-generic:amd64 My machine works fine now (with the old linux-image), but I thought I should inform you of the problem with the new linux-image. P.S. Since xorg is involved I tried to use ubuntu-bug xorg as the instructions said, but there was no way to enter an explanation, and reporting system information with no explanation *now* when my system is *working* would be completely misleading. There seems to be no way to attach any text or message to an ubuntu-bug report. I have attached the output from apport-bug --save=bugfilename linux-image-3.13.0-92-generic:amd64. --- ApportVersion: 2.14.1-0ubuntu3.21 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: david 1900 F.... pulseaudio /dev/snd/controlC0: david 1900 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=907fdd35-197c-4341-9daa-c29636443fb6 InstallationDate: Installed on 2014-06-06 (773 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: Hewlett-Packard HP Pavilion 17 Notebook PC NonfreeKernelModules: fglrx Package: linux (not installed) ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-91-generic.efi.signed root=UUID=1fe70a4d-bce2-4bc1-921f-d793500b9af8 ro quiet splash crashkernel=384M-:128M vt.handoff=7 ProcVersionSignature: Ubuntu 3.13.0-91.138-generic 3.13.11-ckt39 RelatedPackageVersions: linux-restricted-modules-3.13.0-91-generic N/A linux-backports-modules-3.13.0-91-generic N/A linux-firmware 1.127.22 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Tags: trusty Uname: Linux 3.13.0-91-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 11/11/2014 dmi.bios.vendor: Insyde dmi.bios.version: F.35 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 1984 dmi.board.vendor: Hewlett-Packard dmi.board.version: 01.15 dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsyde:bvrF.35:bd11/11/2014:svnHewlett-Packard:pnHPPavilion17NotebookPC:pvr0880100021305B10000620100:rvnHewlett-Packard:rn1984:rvr01.15:cvnHewlett-Packard:ct10:cvrChassisVersion: dmi.product.name: HP Pavilion 17 Notebook PC dmi.product.version: 0880100021305B10000620100 dmi.sys.vendor: Hewlett-Packard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1603655/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
