I haven't seen this bug for very long, but I have a suspicion of what it is.
Now-a-days I use SSD-drives. They are much faster than HDDs. Although, if I run Virtualbox or dd it takes several seconds to unlock the screensaver. I suspect that the screensaver is trying to reach a library or data in the file system on the harddisk and is prevented to do this when other disk operations pending. Sometimes I wait until operation is finished. HDDs are slower and you need to wait a bit longer. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1285258 Title: sometimes GNOME screen lock fails to unlock after password entered To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1285258/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
