[Bug 1617471] Re: Can't login after lock screen (black screen)
What worked for me: install XScreenSaver (via `sudo apt install xscreensaver`), then reboot. Thanks for this workaround from https://askubuntu.com/questions/620709 /blank-screen-after-locking-screen (which has more possible workarounds).

Same issue here. Ubuntu 16.04.2 64-bit, Intel i7-4960X, Gallium 0.4 on NVE7 graphics driver. Although it is a little different. The mouse cursor shows on screen normally. If I use Ctrl+Alt+F(1-6) I can access the terminal windows, but Ctrl+Alt+F7 makes the screen blank again and only the cursor appears. Also this problem started a few days ago, but I have the same OS since 6 months ago. The issue started when I was accessing my computer using Teamviewer 12.0.76279. It started specifically when I had to repeatedly log on and off (the teamviewer connection) to switch between user accounts (I have 2 in my computer). I don't know if this is somehow created the problem or it was just coincidence. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1617471 Title: Can't login after lock screen (black screen) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1617471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
