Are you sure it's a duplicate? This one happened randomly, the other one is described as 100% systematic. This one results in the "Ubuntu..." screen being displayed forever, the other one results in a black screen. In my case the issue disappeared after I uninstalled/purged the nvidia drivers and (probably weeks later) reinstalled them. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1483388 Title: System randomly won't complete boot Status in nvidia-graphics-drivers-340 package in Ubuntu: Confirmed Status in xorg package in Ubuntu: New Bug description: Since the incomplete/broken "fix" for #1431753 was released, and hence NVidia drivers version 340 were installed AND enabled on my machine (where previously I had 331 installed and disabled) this has started happening: About 50-75% of the times (very rough estimation), when I boot, the boot gets stuck at the purple screen with the "Ubuntu" word with four red dots below. Systematically, when this happens, that screen is preceded by a black screen with a lot of errors, of which I attach a picture (yes, I know, it's unreadable, but it's all I can do). If anybody tells me in which log files those errors can be found, I will be happy to attach them. Normally, that is, when the issue does not happen and the boot is succesful, the black screen preceding the purple screen would only contain one line with an unrelated error that has to do with USB.
