xorg segfault on session being locked for extended periods

Asked by Ronno Das

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.

package: xserver-xorg-core 2:1.11.4-0ubuntu10.3
Title: Xorg crashed with SIGSEV in dl_iterate_phdr()

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.

I've also encountered a compiz crash a few times during normal usage, although I don't have the details for that. On restrating compiz in those occassions, the titlebar would still be missing on all the windows that are not maximized, which would more or less force a restart of the system. I don't know if the issues are related.

Hello Ronno,

thank you for bringing this up, but you have entered unfortunally the wrong section. This here is the question section for presenting questions from community to community people for answering. All on good will.

What you need is bugreporting.

For short:

1Press ALT and F2
2type in the software name(exactly)
3See apport starting
4Please describe your problem in a exact way, that makes it a developer which is not familiar with the softeware you use to reproduce the bug(thing of explanation to a beginner - step by step).

Please do this procedure for every software separated. One error one bugreport.

For the long story how to report a bug(recommend to read):

https://help.ubuntu.com/community/ReportingBugs

After this please close this here as solved or when you think it makes sense than link this here with the option on this side to the bugreport.

Thank you in advance
