This morning I installed Ubuntu Gnome 15.04. I installed a few applications and restarted the computer a couple times without issue. I just ran updates though, and when I restarted the computer after updates were finished, the computer hangs at the splash screen with all three dots filled.

Ctrl+Shift+Num Keys does nothing, same with Ctrl+Alt+Del.

The only thing that works to make the computer do something is pressing the power button. The screen will flash the output text from startup. The last two things I see are:

Starting GNOME Display Manager

The text flashes, then it goes back to the splash screen, no longer frozen, then the computer shuts down. I am able to boot from the linux usb drive that I used to install Ubuntu, but am not sure which logs to look at or how to move forward.

UPDATE: Found the boot.log file these are the last few entries:

[[32m  OK  [0m] Started Restore Sound Card State.

If I start in recovery mode, it gives me options for recover, I select continue boot. I receive a message saying that some display manager won't work after recovery boot, that a restart might be necessary. I say continue, then it freezes at a blank screen. I push the power button once, it flashes to a terminal with login prompt and then restarts. I've also tried going into recovery mode and repairing packages with no luck.


Maybe related with this bug?


I've got that issue with Ubuntu Gnome 15.04 after upgrading to Gnome 3.16 (in 3.14 version my laptop works ok).

Hope it helps

  • I don't think I'm having the same issue as I do not have an nvidia graphics card. I was however able to get to a login prompt. I'm going to try to figure out how to revert back to GDM 3.14 – Shannon Phillips Jun 2 '15 at 12:20
  • One of the things that I was told to do was to install lightdm instead of GDM. You could try this too. -Install the Lightdm desktop display manager typing: sudo apt-get install lightdm -During installation you will be asked about what manager do you want (gdm or lightdm). Choose "lightdm". -Reboot If you need (or want) to change the lightdm for gdm, you only have to type: sudo dpkg-reconfigure gdm – Duncan Jun 2 '15 at 14:31
  • Thanks! I'll give that a shot, I did read that going back to 3.14 is no help as certain apps will no longer work properly. – Shannon Phillips Jun 2 '15 at 14:32
  • Switching to lightdm works for now. – Shannon Phillips Jun 2 '15 at 19:26
  • Great! I'm glad it helped you in anyway. – Duncan Jun 3 '15 at 6:14
