Evidently the bug I filed is a duplicate of this (1634242), also with T420s laptops. But I don't even have to put them machines to sleep or even wait. All I have to do is lock the laptop and it crashes.
FYI, I don't get this with Ubuntu, Ubuntu Gnome, or any other derivatives. I tried a newer kernel with the same effect. -- 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
