I have two programs (mplayer and a custom java application) which both present GUI using framebuffers. They run in separate processes. I want to be able to switch from one program to the other without ending/killing the process of the other(the reason is that launching the java program takes a lot of time). I want to simulate sending one of the two programs to background and hiding its GUI and showing the other program's gui.
I am running this on a Raspberry Pi, Debian distribution.
