Mattias H, thank you for reporting this and helping make Ubuntu better. As per http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5428311&swLangOid=8&swEnvOid=4192 an update to your computer's buggy and outdated BIOS is available (1.35). 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. As well, 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 New. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-1.35 ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1549979 Title: xorg freezes upon system boot with kernel 4.2.0-30 Status in xorg package in Ubuntu: Incomplete Bug description: Was working fine with kernel 4.2.0-27, now freezes on boot with kernel 4.2.0-30 $ lsb_release -rd Description: Ubuntu 15.10 Release: 15.10 $ apt-cache policy xorg xorg: Installed: 1:7.7+7ubuntu4 Candidate: 1:7.7+7ubuntu4 Version table: *** 1:7.7+7ubuntu4 0 500 http://se.archive.ubuntu.com/ubuntu/ wily/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: xorg 1:7.7+7ubuntu4 ProcVersionSignature: Ubuntu 4.2.0-27.32-generic 4.2.8-ckt1 Uname: Linux 4.2.0-27-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Thu Feb 25 21:24:38 2016 DistUpgraded: Fresh install DistroCodename: wily DistroVariant: ubuntu DkmsStatus: virtualbox, 5.0.14, 4.2.0-27-generic, x86_64: installed virtualbox, 5.0.14, 4.2.0-30-generic, x86_64: installed virtualbox-guest, 5.0.14, 4.2.0-27-generic, x86_64: installed virtualbox-guest, 5.0.14, 4.2.0-30-generic, x86_64: installed GraphicsCard: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16] (rev 0b) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device [103c:198f] Advanced Micro Devices, Inc.
