Public bug reported: I'm running Ubuntu 12.04 x64 on a reasonably high-end system. If the user session is kept locked for a significant length (say overnight), there is often a delay on resuming, the background for the enter your password screen is not what it should be (instead of having a black background, it's very often like a screenshot, which in theory is also a security risk), and after logging in I receive a your system has encountered a problem dialog.
After ignoring it the first few times, today I saw that it's a segfault in /usr/bin/Xorg. For background info, this is a fresh install, and the only things running in the foreground while the system was locked is firefox. I also have dropbox running in the background. Ubuntu version: 12.04 LTS Package version: xserver-xorg-core 2:1.11.4-0ubuntu10.4 What I expected to happen: the unlock screen appears almost instantly, and shows the ambience background What happened instead: the screen was blank for about a minute or so, and the background looked like a screenshot of the desktop just before it was locked. I don't know if the compiz tag is relevant or not, but since it was automatically included, I'm not removing it.
