** Description changed: On my Dell Vostro 3550, from 11.10 through 14.04 When connecting to an external monitor to extend my desktop the display settings are unstable. 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, a single display on the laptop panel, a single display on the external monitor, or some other undesired combination. In Saucy, I attempted to use the proprietary drivers, but this did not work: * fglrx-installer from the repository (Login screen fine, but logging in produces a black page with only white cursor showing). - * fglrx-installer-updates (Login screen fine, but logging in produces a black page with only white cursor showing). - * Manually installing Catalyst 13.4 - unusable display corruption. + * fglrx-installer-updates (Login screen fine, but logging in produces a black page with only white cursor showing). + * Manually installing Catalyst 13.4 - unusable display corruption. - WORKAROUND: xinput + WORKAROUND: xinput disable 8 + + xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Logitech USB Optical Mouse id=12 [slave pointer (2)] ⎜ ↳ DualPoint Stick id=15 [slave pointer (2)] ⎜ ↳ AlpsPS/2 ALPS DualPoint TouchPad id=16 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] - ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] - ↳ Power Button id=6 [slave keyboard (3)] - ↳ Power Button id=9 [slave keyboard (3)] - ↳ Sleep Button id=10 [slave keyboard (3)] - ↳ Laptop_Integrated_Webcam_FHD id=11 [slave keyboard (3)] - ↳ Dell Dell USB Entry Keyboard id=13 [slave keyboard (3)] - ↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)] - ↳ Video Bus id=8 [slave keyboard (3)] - ↳ Video Bus id=7 [slave keyboard (3)] - ↳ Dell WMI hotkeys id=17 [slave keyboard (3)] - - xinput disable 7 && xinput disable 8 && xinput disable 17 + ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] + ↳ Power Button id=6 [slave keyboard (3)] + ↳ Power Button id=9 [slave keyboard (3)] + ↳ Sleep Button id=10 [slave keyboard (3)] + ↳ Laptop_Integrated_Webcam_FHD id=11 [slave keyboard (3)] + ↳ Dell Dell USB Entry Keyboard id=13 [slave keyboard (3)] + ↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)] + ↳ Video Bus id=8 [slave keyboard (3)] + ↳ Video Bus id=7 [slave keyboard (3)] + ↳ Dell WMI hotkeys id=17 [slave keyboard (3)] --- .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.
