Further comment :
The black screen seen on logout is DIFFERENT to the black screen problem on lid close. Logout will allow a smooth power down on power switch press. Terminal reports normal activity. This could be the backlight issue reported elsewhere? On lid close the only recourse is forced power down. Often there is a frozen mouse cursor visible. -- 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
