With a default xubuntu 14.10 install on 2 different laptops (MacBook Air 4,1 and HP folio 9470m) I can reproduce this issue. For me the black screen occurs after login.
Adjusting power management settings has not yet helped. I did find that I can solve the problem by reclosing the lid, waiting for suspend and opening it again. The 2nd time seems to work as expected. -- 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/linux/+bug/1357090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
