I'm running multiple virtual screens in a 3x2 configuration using a combination of Xdmx, Xvnc and Xpra-- that is, I have six monitors in a block configuration single desktop spanning the the indivdual displays by Xdmx, using Xvnc to implement screens, and Xpra to manage apps.
A common problem is that an application window in the initial graphical session will steal the cursor/typing focus, preventing me from using the keyboard to type into the spanned Xdmx screen.
Solution for moving the focus of active typing back to the Xdmx screen session? TIA.
