This also occurs for me using 14.04, and WinXP vbox client. I resort to Right Ctrl then Ctr+Alt+<arrow> to switch workspace from vbox workspace (this all occurs in the background). Occasionally I also then need to put the machine into standby using the mouse to access the menu in the top right corner. The keyboard usually gets focus back when waking from standby. $ lsb_release -rd: Description: Ubuntu 14.04 LTS Release: 14.04 $ apt-cache policy virtualbox virtualbox: Installed: 4.3.10-dfsg-1 Candidate: 4.3.10-dfsg-1 Version table: *** 4.3.10-dfsg-1 0 500 http://au.archive.ubuntu.com/ubuntu/ trusty/multiverse i386 Packages 100 /var/lib/dpkg/status -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1317396 Title: VirtualBox fullscreen grabs keyboard, can't type password from locked screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1317396/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
