espantaperros, thank you for reporting this and helping make Ubuntu better.
As per http://www.acer.com/ac/en/US/content/drivers an update to your computer's buggy and outdated BIOS is available (R01.A4L). 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 ** Tags added: bios-outdated-r01.a4l ** Changed in: xorg (Ubuntu) Importance: Undecided =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/1510926 Title: problem driver intel 4 seriesa chipset integrated graphics controller Status in xorg package in Ubuntu: Incomplete Bug description: hi ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: xorg 1:7.7+7ubuntu4 ProcVersionSignature: Ubuntu 4.2.0-16.19-generic 4.2.3 Uname: Linux 4.2.0-16-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.19.1-0ubuntu4 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: Wed Oct 28 13:38:24 2015 DistUpgraded: 2015-10-27 09:32:49,838 DEBUG enabling apt cron job DistroCodename: wily DistroVariant: ubuntu DkmsStatus: virtualbox, 5.0.4, 3.19.0-31-generic, x86_64: installed virtualbox, 5.0.4, 4.2.0-16-generic, x86_64: installed ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation 4 Series Chipset Integrated Graphics Controller [8086:2e12] (rev 03) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device [1025:0151] Subsystem: Acer Incorporated [ALI] Device [1025:0151] InstallationDate: Installed on 2015-05-07 (174 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) MachineType: Acer Veriton S670G ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.2.0-16-generic root=UUID=b0cd3f1a-045d-4b5e-87f4-bf104916c033 ro quiet splash vt.handoff=7 SourcePackage: xorg UpgradeStatus: Upgraded to wily on 2015-10-27 (1 days ago) dmi.bios.date: 11/20/2008 dmi.bios.vendor: Acer dmi.bios.version: R01-A2L dmi.board.name: EQ45M dmi.board.vendor: Acer dmi.chassis.type: 3 dmi.chassis.vendor: Acer dmi.modalias: dmi:bvnAcer:bvrR01-A2L:bd11/20/2008:svnAcer:pnVeritonS670G:pvr:rvnAcer:rnEQ45M:rvr:cvnAcer:ct3:cvr: dmi.product.name: Veriton S670G dmi.sys.vendor: Acer version.compiz: compiz 1:0.9.12.2+15.10.20151015-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.64-1 version.libgl1-mesa-dri: libgl1-mesa-dri 11.0.2-1ubuntu4 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 11.0.2-1ubuntu4 version.xserver-xorg-core: xserver-xorg-core 2:1.17.2-1ubuntu9 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.9.2-1ubuntu1 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.5.0+git20150819-0ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20150808-0ubuntu4 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.11-1ubuntu3 xserver.bootTime: Wed Oct 28 09:47:04 2015 xserver.configfile: default xserver.devices: input Power Button KEYBOARD, id 6 input Power Button KEYBOARD, id 7 input Cherry GmbH SmartBoard XX44 KEYBOARD, id 8 input Logitech USB Optical Mouse MOUSE, id 9 xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 1935 vendor MAX xserver.version: 2:1.17.2-1ubuntu9 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1510926/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
