I have already installed the latest kernel from Ubuntu mainline kernels (3.14 trusty). The problem still exists.
** Tags added: apport-collected compiz-0.9 trusty ubuntu ** Description changed: I have a Samsung Series 7 Chronos 700Z3A-S02DE. It uses an i5-2450m (Intel HD2000) and an AMD 6490m dedicated graphics card. Since Ubuntu 14.04 uses Linux kernel 3.13 it enables dpm by default. This causes the graphics card to be shut down to dynoff when not used and should make it use (almost) no power. However, the laptop fans are working all the time and the laptop produces quite a lot of heat (the CPU does not heat as sensors are at 60°C). The sensor for the graphcis card always shows -128°C. Using powertop it reveals that the laptop consumes around 34W on battery. Looking on the list where the usage is shown per device it shows the radeon graphics card with 0%. I think there is a bug and the graphics card is NOT shutdown correctly to not use any noticable power. - I would appreciate if I can help you to find the issue and if you need - any more information. + I would appreciate if I can help you to find the issue and if you need any more information. + --- + .tmp.unity.support.test.0: + + ApportVersion: 2.14.1-0ubuntu1 + 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 + DistUpgraded: Fresh install + DistroCodename: trusty + DistroRelease: Ubuntu 14.04 + DistroVariant: ubuntu + DkmsStatus: + bcmwl, 6.30.223.141+bdcom, 3.13.0-20-generic, x86_64: installed + bcmwl, 6.30.223.141+bdcom, 3.13.0-21-generic, x86_64: installed + bcmwl, 6.30.223.141+bdcom, 3.13.0-23-generic, x86_64: installed + ExtraDebuggingInterest: Yes, if not too technical + GraphicsCard: + Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) + Subsystem: Samsung Electronics Co Ltd Device [144d:c0b3] + Advanced Micro Devices, Inc.
