The problem happens even without acpi_osi= option. I'm now updating this bug from an XFCE session, with which the problem doesn't happen. It always happens when logging in on Unity. This behavior started to happen only recently (about last week), after an update. Before that day it worked even with nvidia drivers installed.
** Description changed: After a recent update, it's no more possible to log in to Ubuntu 16.04 trough lightdm with Unity. I'm attaching .xsession-errors hoping it can be useful. - I'm reporting this from another partition with Trusty, because I did'n - know how to report without any GUI. I'm willing to add details if anyone - helps me on how to send them from the CLI. + ******************************************* + Workaround: + remove all the nvidia drivers. + You won't have graphics accelerated but at + least you can log in on Unity. + + sudo apt purge nvidia* + + ******************************************* ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xorg 1:7.7+13ubuntu1 ProcVersionSignature: Ubuntu 4.3.0-7.18-generic 4.3.3 Uname: Linux 4.3.0-7-generic x86_64 .tmp.unity.support.test.0: - + ApportVersion: 2.19.4-0ubuntu2 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 CurrentDesktop: Unity Date: Tue Feb 9 20:11:26 2016 DistUpgraded: Fresh install DistroCodename: xenial DistroVariant: ubuntu DkmsStatus: - bbswitch, 0.8, 4.3.0-5-generic, x86_64: installed - bbswitch, 0.8, 4.3.0-7-generic, x86_64: installed - bbswitch, 0.8, 4.4.0-2-generic, x86_64: installed - psmouse-focaltech, 0.1, 3.19.0-18-generic, x86_64: installed - psmouse-focaltech, 0.1, 3.19.0-20-generic, x86_64: installed + bbswitch, 0.8, 4.3.0-5-generic, x86_64: installed + bbswitch, 0.8, 4.3.0-7-generic, x86_64: installed + bbswitch, 0.8, 4.4.0-2-generic, x86_64: installed + psmouse-focaltech, 0.1, 3.19.0-18-generic, x86_64: installed + psmouse-focaltech, 0.1, 3.19.0-20-generic, x86_64: installed ExtraDebuggingInterest: Yes GraphicsCard: - Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) - Subsystem: ASUSTeK Computer Inc. 4th Gen Core Processor Integrated Graphics Controller [1043:178d] + Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) + Subsystem: ASUSTeK Computer Inc. 4th Gen Core Processor Integrated Graphics Controller [1043:178d] InstallationDate: Installed on 2015-03-21 (325 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Alpha amd64 (20150321) Lsusb: - Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub - Bus 001 Device 003: ID 0bda:57b4 Realtek Semiconductor Corp. - Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub + Bus 001 Device 003: ID 0bda:57b4 Realtek Semiconductor Corp. + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub MachineType: ASUSTeK COMPUTER INC.
