** Description changed: Running kernel on Ubuntu 14.04.2. At random times, (especially when touching the touchpad after not touching it for a period of time), the display goes black ! Using QHD display resolution : 3200x1800 More information about hardware can be found here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1434963 Otherwise 14.04.2 runs fine / perfectly on this brand-new machine. It also seems to happen after the system had been successfully recovered from suspending. Also, it one time, just wanted to switch on to resume, and the whole display went 'disco', meaning, it was flashing wildly, recovery impossible... Any help would be greatly appreciated, since HP claims they 'support' 14.04 on this Workstation. --- ApportVersion: 2.14.1-0ubuntu3.7 Architecture: amd64 CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2015-03-21 (2 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) Package: linux (not installed) Tags: trusty Uname: Linux 4.0.0-040000rc5-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True + --- + ApportVersion: 2.14.1-0ubuntu3.7 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: eric 1540 F.... pulseaudio + /dev/snd/controlC1: eric 1540 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=5565fff9-d47c-465c-9ef6-7bb37610caca + InstallationDate: Installed on 2015-03-21 (2 days ago) + InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) + MachineType: Hewlett-Packard HP ZBook 15 G2 + Package: linux (not installed) + ProcFB: 0 radeondrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-31-generic root=UUID=81792a20-09a6-47d9-be7f-0a6de44a41dd ro quiet splash vt.handoff=7 + ProcVersionSignature: Ubuntu 3.16.0-31.43~14.04.1-generic 3.16.7-ckt5 + RelatedPackageVersions: + linux-restricted-modules-3.16.0-31-generic N/A + linux-backports-modules-3.16.0-31-generic N/A + linux-firmware 1.127.11 + RfKill: + 0: phy0: Wireless LAN + Soft blocked: yes + Hard blocked: no + Tags: trusty + Uname: Linux 3.16.0-31-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 02/26/2015 + dmi.bios.vendor: Hewlett-Packard + dmi.bios.version: M70 Ver. 01.07 + dmi.board.name: 2253 + dmi.board.vendor: Hewlett-Packard + dmi.board.version: KBC Version 03.10 + dmi.chassis.type: 10 + dmi.chassis.vendor: Hewlett-Packard + dmi.modalias: dmi:bvnHewlett-Packard:bvrM70Ver.01.07:bd02/26/2015:svnHewlett-Packard:pnHPZBook15G2:pvrA3008CD10003:rvnHewlett-Packard:rn2253:rvrKBCVersion03.10:cvnHewlett-Packard:ct10:cvr: + dmi.product.name: HP ZBook 15 G2 + dmi.product.version: A3008CD10003 + dmi.sys.vendor: Hewlett-Packard -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1435584 Title: Randomly freezing display HP Zbook 15 G2 AMD FirePro M5100 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1435584/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
