Then I wake up computer after suspend, it just reboots. This happens with X.org ATI driver only, but with fglrx I'm greeted with a black screen (even backlights are turned off) and I have to reboot anyway. (but whatever, fglrx works horrible, I would never install it back) ALSO, computer wakes up normally on latest upstream kernel (4.5.0-040500rc1-generic) ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-25-lowlatency 4.2.0-25.30 ProcVersionSignature: Ubuntu 4.2.0-25.30-lowlatency 4.2.6 Uname: Linux 4.2.0-25-lowlatency x86_64 ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: potato 2548 F.... pulseaudio /dev/snd/controlC1: potato 2548 F.... pulseaudio CurrentDesktop: Unity Date: Tue Jan 26 20:19:24 2016 HibernationDevice: RESUME=UUID=2277e00a-0411-4136-b180-2892752df2e0 InstallationDate: Installed on 2016-01-17 (9 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) MachineType: Acer Aspire 7540 ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.2.0-25-lowlatency root=UUID=ae6c8d51-38da-4c25-9281-6b9ceac5b2ca ro quiet splash acpi_sleep=nonvs quiet splash acpi_sleep=nonvs vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-4.2.0-25-lowlatency N/A linux-backports-modules-4.2.0-25-lowlatency N/A linux-firmware 1.149.3 SourcePackage: linux UdevLog: Error: [Errno 2] Нет такого файла или каталога: '/var/log/udev' UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 12/07/2009 dmi.bios.vendor: Phoenix Technologies LTD dmi.bios.version: V1.11 dmi.board.name: JV71TR dmi.board.vendor: Acer dmi.board.version: Rev dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: None dmi.modalias: dmi:bvnPhoenixTechnologiesLTD:bvrV1.11:bd12/07/2009:svnAcer:pnAspire7540:pvr0100:rvnAcer:rnJV71TR:rvrRev:cvnAcer:ct10:cvrNone: dmi.product.name: Aspire 7540 dmi.product.version: 0100 dmi.sys.vendor: Acer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1538202/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
