Public bug reported: After update from kernel 4.2.0-18 to 4.2.0-19, my wifi got broken and the video driver had some problems too, because my resolution was downgraded to 1024x768. Boot startup screen was changed from a graphics mode to a low resolution text mode (25x80 maybe).
I had to boot back to 4.2.0-18 to report this bug. Please let me know what extra information is needed. >From /var/log/apt/history.log: Start-Date: 2015-12-02 07:38:24 Commandline: /usr/bin/unattended-upgrade Install: linux-headers-4.2.0-19:amd64 (4.2.0-19.23, automatic), linux-headers-4.2.0-19-generic:amd64 (4.2.0-19.23, automatic), linux-image-extra-4.2.0-19-generic:amd64 (4.2.0-19.23, automatic), linux-image-4.2.0-19-generic:amd64 (4.2.0-19.23, automatic) Upgrade: linux-headers-generic:amd64 (4.2.0.18.20, 4.2.0.19.21), thunderbird-locale-en-us:amd64 (38.3.0+build1-0ubuntu2, 38.4.0+build3-0ubuntu0.15.10.1), thunderbird:amd64 (38.3.0+build1-0ubuntu2, 38.4.0+build3-0ubuntu0.15.10.1), thunderbird-locale-en:amd64 (38.3.0+build1-0ubuntu2, 38.4.0+build3-0ubuntu0.15.10.1), thunderbird-locale-fi:amd64 (38.3.0+build1-0ubuntu2, 38.4.0+build3-0ubuntu0.15.10.1), thunderbird-gnome-support:amd64 (38.3.0+build1-0ubuntu2, 38.4.0+build3-0ubuntu0.15.10.1), linux-libc-dev:amd64 (4.2.0-18.22, 4.2.0-19.23), linux-image-generic:amd64 (4.2.0.18.20, 4.2.0.19.21), linux-generic:amd64 (4.2.0.18.20, 4.2.0.19.21) ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-19-generic:amd64 4.2.0-19.23 ProcVersionSignature: Ubuntu 4.2.0-18.22-generic 4.2.3 Uname: Linux 4.2.0-18-generic x86_64 ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: nikke 4087 F.... pulseaudio CurrentDesktop: Unity Date: Fri Dec 4 21:20:27 2015 HibernationDevice: RESUME=UUID=46f62d42-a77b-4f1a-be16-b3b015057bd6 InstallationDate: Installed on 2014-06-25 (527 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: LENOVO 42912WG ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.2.0-18-generic root=/dev/mapper/ubuntu--vg-root ro vesafb.invalid=1 splash quiet nopat RelatedPackageVersions: linux-restricted-modules-4.2.0-18-generic N/A linux-backports-modules-4.2.0-18-generic N/A linux-firmware 1.149.2 SourcePackage: linux UpgradeStatus: Upgraded to wily on 2015-11-19 (15 days ago) dmi.bios.date: 07/18/2013 dmi.bios.vendor: LENOVO dmi.bios.version: 8DET69WW (1.39 ) dmi.board.asset.tag: Not Available dmi.board.name: 42912WG dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr8DET69WW(1.39):bd07/18/2013:svnLENOVO:pn42912WG:pvrThinkPadX220:rvnLENOVO:rn42912WG:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 42912WG dmi.product.version: ThinkPad X220 dmi.sys.vendor: LENOVO ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug wily ** Attachment added: "/var/log/apt/term.log" https://bugs.launchpad.net/bugs/1522944/+attachment/4529734/+files/apt-term.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1522944 Title: Wifi broken and strange screen resolution after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1522944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
