As Marc suggested if you turn off the visual effects the issue does go away. System -> Preferences -> Appearance -> Visual Effects -> set to none
I experienced the issue while compiz was on, turning compiz off fixed it, and restarting compiz reintroduced it. If you go to a terminal session (while visual effects are set to none) and type compiz (which turns the visual effects on) and then lock the machine and plug in a flash drive the issue still exist. -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/702048 Title: Screen locking issue -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
