This issue still persists in Ubuntu Gnome 14.04.2 I could consistently reproduce by installing fresh and then installing steam (and its dependencies). I was not able to restart gdm and login as it just froze in tty7 (the other terminals worked). When doing a hard reset of my computer it would then hang at the grey screen with the gnome logo and the three loading dots .
Installing Ubuntu Gnome 15.04 to hopefully resolve this issue -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdm in Ubuntu. https://bugs.launchpad.net/bugs/1414707 Title: Login fails, returns to login and flickering prevents password typing Status in Ubuntu GNOME: Fix Released Status in gdm package in Ubuntu: Fix Released Bug description: I was testing Ubuntu Gnome 15.04 in VirtualBox. I was able to login into the machine a few times and run updates and install a few programs. I also installed the VirtualBox guest additions. Since today this happens: I log into the machine. The login is accepted and the machine does something for a few seconds. Then the machine jumps back to login, but with a random flickering. The flickering also resets the password field, which prevents it from being typed. So I can't login into the machine anymore. I am using a HP Probook 6570 b which I upgraded to 16 GB of RAM. The iso was from the 20th of January, but I did a daily sudo apt-get upgrade on it.
