ABRT linked me here. https://retrace.fedoraproject.org/faf/reports/88460/ Here are additionnal info: - Thinkpad laptop with workstation and one external display connected (LVDS1+HDMI3 (primary)) - Halting or sleeping the laptop works nice when using the gnome-shell action (top right active corner menu) with both - I get a freeze (which is a kernel oops as I can read on the log) when closing the laptop: it tries to sleep (default feature when closing the laptop screen) but fails. When the primary screen is on the external display. I will check once more but I think it does not crash when the primary screen is on the laptop (lvds). Then it should be related to GNOME?
Created attachment 739301 [details] crash log
I've had this happen both with the external display mirroring the laptop screen and with no external display, and with a 32-bit kernel (3.8.4-102.fc17.i686.PAE). It happens sometimes when I close the lid (without suspending) and open it again.
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
