I tried today from a live Ubuntu 16.04 environment for a shorter amount of time, this time with the right bitness and Chrome version 50. I still cannot reproduce the issue. I noticed that this issue is most easily reproduced when I try and launch Chrome as soon as possible after booting up. This is difficult to reproduce on a live environment as I have to first download and install the package. -- 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/1540553 Title: task Xorg:1042 blocked for more than 120 seconds in schedule+0x37/0x80 Status in xorg package in Ubuntu: Incomplete Bug description: Since system updates on or after Thursday 28th, I have been experiencing complete system freezes when attempting to do tasks such as opening a menu or a window.
