This has been driving me nuts for weeks. I would lose my entire X session every single day as soon as the screen blanked... quite troublesome when you're trying to make linux work as your daily drive, haha.
*Confirmed fix* w/ the patch suggested on xfce's bugzilla: https://bugzilla.xfce.org/show_bug.cgi?id=11107#c53 Download the xfce4-settings source, apply the patch, increment with a non-maintainer version number (for no future apt-get conflicts once this gets an official fix), and reinstall your patched xfce4-settings. I had to learn how to patch a .deb file properly in the process, but that was worth it too. -- Hardware/Software -- GPU: GTX 970 over DisplayPort 1.2 Monitor: Dell P2715 (4K@60Hz, hardware rev A03) OS: Xubuntu Xenial (16.04 LTS) Manually patched xfce4-settings version: 4.12.0-2ubuntu1 Useful links on patching .deb's: https://help.ubuntu.com/community/UpdatingADeb http://www.cyberciti.biz/faq/appy-patch-file-using-patch-command/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1379702 Title: xfsettingsd crashes after disconnecting external screen To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-settings/+bug/1379702/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
