** Description changed: Hello, I'm using Dell XPS15z laptop with kubuntu 12.10 beta 1 and kernel 3.5.0-13 amd64 (additional kernel flags: acpi=noirq). The problem is that ubuntu with this kernel boots up in a black screen: it looks like monitor gots powered off. + + After several reboots I'm able too start ubuntu normally. I mean that + bug happens frequently but not every time. Besides, the laptop has hibrid graphics: nVidia 525M GT and Intel HD: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev a1) (prog-if 00 [VGA controller]) Bumblebee is not installed. Maybe the new X.org 1.13 desides that display is connected to nVidia card and outputs graphics through discrete graphics ?(nvidia-current drivers are installed). For now I have no opportunty to check nVidia card iutput (e.g. via discrete HDMI), I'll check it tomorrow. But everyting's ok with mainline (3.5.3) kernel from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.3-quantal/ ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: linux-image-3.5.0-14-generic 3.5.0-14.15 ProcVersionSignature: Ubuntu 3.5.0-14.15-generic 3.5.3 Uname: Linux 3.5.0-14-generic x86_64 AcpiTables: Error: command ['pkexec', '/usr/share/apport/dump_acpi_tables.py'] failed with exit code 127: Error executing /usr/share/apport/dump_acpi_tables.py: Permission denied ApportVersion: 2.5.1-0ubuntu7 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: elvenfighter 1913 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: elvenfighter 1913 F.... pulseaudio CRDA: - country TW: - (2402 - 2472 @ 40), (3, 27) - (5270 - 5330 @ 40), (3, 17), DFS - (5735 - 5815 @ 40), (3, 30) + country TW: + (2402 - 2472 @ 40), (3, 27) + (5270 - 5330 @ 40), (3, 17), DFS + (5735 - 5815 @ 40), (3, 30) Date: Sun Sep 9 10:28:33 2012 HibernationDevice: RESUME=UUID=8fccd069-699f-41c0-9f34-7d61aa3a4530 InstallationMedia: Kubuntu 12.10 "Quantal Quetzal" - Alpha amd64 (20120905) MachineType: Dell Inc.
