Daniel Centore, thank you for reporting this and helping make Ubuntu better. Natty reached EOL on October 2012. Please see this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We were wondering if this is still an issue in a supported release? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux replace-with-bug-number Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag: needs-upstream-testing This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text: needs-upstream-testing If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. Please let us know your results. Thank you for your understanding.

Removing v86d also fixes the freeze for me on the nvidia machine so, for me at any rate, that seems to have been the root cause. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/767927 Title: Logout Freeze [kernel tried to execute NX-protected page - exploit attempt?

I have the same issue here after upgrading to 11.04. A workmate of mine installed a fresh copy on identical hardware and does experience the issue, issue could be upgrade related. It's diffidently related to VT switching. If I switch terminals, the issue occurs (ctrl-alt-f1).

Yes, the revert script fixes the logout/shutdown freeze for me on the fglrx machine. http://www.kyleabaker.com/downloads/ubuntu/scripts/plymouth-resolution-fix-revert-back.sh.zip I had forgotten that I had tinkered with the plymouth settings in 10.10 to get rid of an ugly bootsplash - self inflicted bug :) I'll try in tomorrow on the nvidia machine that is showing similar symptoms.

The key is to run sudo apt-get purge v86d - Daniel try this command If I install that package (v86d) and execute /sbin/v86d, the console will lock up immediately when switching VTs. v86d is not included by default on a fresh stock Ubuntu install. It's also a good idea to set the Plymouth theme back to default, if you changed it sudo update-alternatives --config default.plymouth -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/767927 Title: Logout Freeze [kernel tried to execute NX-protected page - exploit attempt?

[Bug 767927] Re: Logout Freeze [kernel tried to execute NX-protected page - exploit attempt? (uid: 0)]
mia I do not have v86d installed. Also, I disabled plymouth (as described above) and updated many packages. Around the same time, the freezes stopped for me. I do not want to re-enable plymouth because I need a production machine for the time being. Some of the others who still have this problem might like to try this though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/767927 Title: Logout Freeze [kernel tried to execute NX-protected page - exploit attempt?
