@Thaddäus same behaviour if upower is removed or not, Same behaviour is xfce- power-manager is removed or not, EXCEPT that the first time the laptop lid is closed after reboot OR logoff expressly invoked, all works well. After that, the same behaviour is seen.
@Sean The laptop only sees the login screen after a logoff. The system is set to auto-logon. A reminder that this all worked perfectly with 12.04 LTS from first install right up to the latest 12.04.4 LTS updates. The problem only started on a new install of 14.04.1 LTS as reported above. The installation is absolutely standard. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1357090 Title: Black screen on resume in Xubuntu 14.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1357090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
