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.
