When connecting the laptop to an external monitor to extend my desktop the display settings are unstable. I choose to enable both the laptop panel, and the external monitor setting appropriate resolutions and apply settings. Sometimes the chosen settings do not "take". If they do apply, and I confirm that I want to keep the settings, at random intervals the display settings are auto-changed by the system. This may include: - Resetting to "mirrored" displays at 1024x768 - Resetting to a single display on the laptop panel - Resetting to a single display on the external monitor - Some other weird combination. E.g. When using my computer in a time range of 10 minutes i could get through 5 different dispositions and resolutions. It could be both display working fine, then only one but with wrong resolution, then the two again but with mirror, then just the second, and so on. --- .tmp.unity.support.test.0: ApportVersion: 2.12.7-0ubuntu6 Architecture: i386 CasperVersion: 1.336ubuntu1 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 ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:04cd] Advanced Micro Devices, Inc.
