** Description changed: Current release: Ubuntu 14.04.3 LTS Current version: v3.13.0.68.74 Expected behavior: System boots to GUI showing chromium-browser What happened: Booted to black screen After updating my linux kernel from v3.13.0.32.38 to v3.13.0.68.74, my system does not boot into the GUI properly anymore. X11 starts up and I have confirmed that I can interact with the screen that should be there via keyboard (using chromium logs, I can confirm that I can open new tabs with CTRL+T), but the screen is completely black. If I restart nodm, X11 restarts and comes up as it should. If I simply switch to the vivid kernel (v3.19.0.33.20) on the same system the problem goes away and the system boots properly every time, as well as the system working fine until I update just the linux-generic package. Other possibly useful information: - Every time the system boots to a black screen, plymouth does not appear while booting nor can I TTY switch to it after booting (instead the TTY it should be on is a black screen with a blinking cursor), which is opposite of the behavior observed when the system boots properly. - Attached Xorg.0.log (produced from a bad boot). + --- + AlsaDevices: + total 0 + crw-rw---- 1 root audio 116, 1 Jan 15 11:11 seq + crw-rw---- 1 root audio 116, 33 Jan 15 11:11 timer + AplayDevices: Error: [Errno 2] No such file or directory + ApportVersion: 2.14.1-0ubuntu3.19 + Architecture: i386 + ArecordDevices: Error: [Errno 2] No such file or directory + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + CRDA: Error: [Errno 2] No such file or directory + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=c64ce442-021a-4873-934f-770057560a1d + InstallationDate: Installed on 2015-05-21 (238 days ago) + InstallationMedia: Ubuntu-Server 14.04.1 LTS "Trusty Tahr" - Release i386 (20140722.3) + IwConfig: + p3p1 no wireless extensions. + + lo no wireless extensions. + MachineType: To be filled by O.E.M.
