Managed to fix my issue by switching to the nVidia proprietary driver. I had a look at my Xorg.0.log and noticed that *none* of the drivers seemed to be activating successfully. It looks like Nouveau eventually kicked in, even after showing a failed to load message, but I'm not sure what the implications of that are.
Went to Additional Drivers and saw two proprietary nVidia drivers there, neither of which were activated. Selected the top driver, listed as recommended, and now am no longer locking up when I close/open the screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/966744 Title: resume from suspend leaves me with black screen and a cursor To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/966744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
