I have the same problem, I believe. I am running Loki on a Toshiba Satelite L755-s5112.
When logging in after suspend or sleep it will freeze and or go to black screen. No matter how long I wait it doesn't come out of it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1621719 Title: Black screen when resuming laptop from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/elementaryos/+bug/1621719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
