Hello Ryan, or anyone else affected, Accepted unity-settings-daemon into utopic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source /unity-settings-daemon/14.04.0+14.10.20141014-0ubuntu1.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

Sorry, I lied about utopic not being affected. The corresponding code in unity-settings-daemon does fail -- differently, but it does fail. Patch to follow shortly, after I check vivid... ** Also affects: unity-settings-daemon (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-desktop3 in Ubuntu. https://bugs.launchpad.net/bugs/1416081 Title: (FreeNX/X2Go) gnome-session crashed with SIGSEGV in gnome_idle_monitor_get_idletime() Status in gnome-desktop3 package in Ubuntu: New Status in unity-settings-daemon package in Ubuntu: New Bug description: The X server used by FreeNX and X2Go does not support the IDLETIME counter.
